2.0 BICC CABLES QUALIFICATIONS2.1 PerformanceBICC Cables can provide optimum cables performance, and has access to the latest development inconductor, insulation and protective materials technology. Our experienced technical staff can provideguidance on cable selection and installation.Where necessary, special features can be incorporated into the cable enabling it to have: Improved fire performance. Low smoke and fume ( Halogen free ). Termite resistance, Resistance to attack from oils, solvents or corrosive chemicals.BICC Cables Technical Engineers will be glad to provide assistance to ensure you get the rightcable that fully complies with your applications.Specifying the right cable for a particular application is the first step. However, the key to reliability is in themanufacturing process. The cable must be from high quality material and manufactured ensuring that nodefects or weaknesses will be revealed in service.BICC Cables constantly monitors all manufacturing processes and operates the most stringent qualityassurance procedures to give you excellent reliability. It is a factor which assumes vital significance whencables are to be installed in locations where future access would be difficult. That is when BICC cables andresources will give peace of mind.2.2 SafetyBICC Cables is able to maintain a close watch on development in cable technology and regulations, andtherefore ensure that our products are designed and constructed to be hazard free under the prescribedconditions of use.BICC Cables uses only tried and tested materials and processes in full compliance with all the relevantBritish and International standards. therfore, our cables are manufactured for safe use, without the riskto health, on the understanding that users will exercise the same degree of care in their selection andapplication.Industrial safety is also an important issue with BICC Cables and is strictly applied to the company’s ownoperations.8
2.3 ISO 9001: 2015BICC Cables Quality Management system, from thestart of manufacture is in conformance to:ISO 9001 : 2015 BICC Cables is certified to ISO 9001 by the BritishStandards Institute (BSI-UK) which is an international recognizedaccreditation body with uncompromising standards.ISO 9001: 2015 is an international standard which defines, forsuppliers and manufacturers, what is required of quality oriented management system. Essentially, itrequires the certified company to draw up written procedures to ensure full compliance with all requirementsof the standard. The procedures are strictly followed by every department in the company, thus ensuringthat the goods leaving the factory are of the highest quality and meet each customer’s requirements inevery respect.9
3.0 PRODUCT CONSTRUCTIONThe PVC & XLPE insulated power cables details in this publication are rated at 0.6/1 kV. Details of BICCCables 1.8/3.3 kV rated cables are available on request. Both steel tape and steel wire armoured andunarmoured designs are included. These conform specifically to IEC60502, Cables can also be supplied tothe National Standards of other countries.3.1 ConductorsIt is the current carrying component of the cable.The conductors in BICC Cables fixed power cables are of high conductivity copper or high purity aluminiumand all meet the requirements of IEC60228 “Conductors in insulated cables and cords”.The flexibility degree is described as: Conductor to class 1 ( solid conductor, where no strand wires). Conductor to class 2 ( stranded wires like 7 wires, 19 wires, 37 wires, and 61 wires). Conductor to class 5 ( more number of wires inside the conductor to make the conductor flexible ). Conductor to class 6 ( like class 5, but with more number of wires and more flexible to be used in cords).Dependent upon the actual cable type, conductors may be stranded copper or aluminium. Smaller sizes arecircular in profile; larger conductors are shaped or tightly compacted to reduce their physical size.This compacting sometimes entails a change in the number and size of wires and therefore conductorsare generally categorized by their nominal cross sectional area rather than by their stranding configuration.3.2 InsulationIn accordance with this technical guide, cables are insulated with PVC (Polyvinyl Chloride) or XLPE( Cross Linked Polyethylene ) or Low Smoke Zero Halogen (LSOH).PVC InsulationPVC as per IEC 60502 is a clean, easy to handle material with good electrical characteristics and resistanceto water, oils and chemicals, together with inherent toughness and flexibility over a wide temperature range.PVC cables are easy to handle joints, terminates and have an outstanding record of trouble free service.PVC is inherently flame retardant and is suitable for a maximum operating temperature of 70 OC.All of the cables in this publication meet the requirements of IEC 60332, “Test on electrical cables under firecondition”, part 1 “Method of test on a single vertical insulated wire or cables”.Under some unfavorable circumstances PVC can burn and fire may even propagate along the cables.However, types of oversheath incorporating special developed compounds to overcome fire hazards areavailable, as described later ‘over sheath’. Additional information and quotations for these oversheath willbe supplied upon request.10
XLPE InsulationCross linked polyethylene ( XLPE ) type GP 8 as per BS 7655 and IEC 60502 requirements.XLPE matches many of the attributes of PVC, although it is not flame retardant, but goes a stage or twofurther. The good qualities of polyethylene are retained but at high temperatures the toughness and physicalproperties are improved. In particular, there is greatly enhanced resistance to deformation.Having superior thermal and mechanical properties compared with PVC, the XLPE also has higher insulationresistance, enabling its thickness to be reduced, leading to corresponding reduction in the overall diameterand weight of a finished cable.The main comparative consideration however, is that XLPE permits the operating temperature of cables tobe raised substantially without suffering thermal deformation or degradation.The continuous current rating of XLPE insulated cables are based upon a maximum conductor temperature of90 OC as opposite to 70 OC for PVC insulated types.Short circuit rating are also higher, XLPE accepted 250 OC as a final conductor temperature at the end ofshort circuit compared with 140/160 OC for PVC insulated cables. As a result, in situations where conductorsize is governed by current rating rather than voltage drop, it may be possible to use a smaller conductorsize.3.3 Core IdentificationN . CoresCore Colors1Black or Red2Red, Black3Red, Yellow, Blue3.5Red, Yellow, Blue, Black4Red, Yellow, Blue, BlackBlack identifies the neutral conductor and the other colors identify the phase conductors in two, three, three& half, and four cores cables.All core colors are available as per customer request.3.4 FillersNon-hygroscopic polypropylene fillers are included between laid up cores as standard.It is optional according to cable size and where necessary.3.5 Binding TapeA separator tape of polypropylene ( PP tape ) or polyester mylar tape is applied over the laid up coreswhere necessary.11
INTRODUCTION3.0 PRODUCTCONSTRUCTION3.6 BeddingA layer of extruded PVC is applied around the laid up cores separating the heart of the cable from themetallic armour and providing a secure bending.Reduced propagation flame retardant (FR PVC) compound may be used for reduced propagationcharacteristic.Halogen Free Flame-Retardant (HFFR) or LSOH ,LSZH and LSHF compounds may be used for installationwhere fire hazard exists. It is a low smoke, low toxic compound when fired.3.7 ArmourArmour is necessary to protect the conductors from mechanical damage.Armour may be provided for using:Steel tape (STA) Double steel tape of thickness 0.2 or 0.5 is applied helically over bedding.Steel wire (SWA) one layer of round wires is applied helically over the bedding.Steel wire with hard drawn tinned copper wire to increase conductivity.For single core cables used for AC. purposes, it is not recommended to use magnetic armoured cables,since the eddy current will affect the cable, so if armouring is essential, Aluminum wire (AWA) can be usedas a cable armour .Note!Under short circuit conditions, steel tape armour has high earth fault loop impedance, so the steel wirearmour can carry more short circuit current.12
3.8 OversheathPVCThe standard sheath of all cables is an extruded layer of black PVC, the external surface of which isembossed with voltage, rating and cable size. Normally the over sheath PVC grade meets the requirementsof BS 7655. Other grades can be used dependent upon customer requirements e.g. PVC sheath withanti-termite properties can be provided when specified.Ordinary PVC is intrinsically flame retardant and all cables described in this publication meet therequirements of IEC 60332 part 1 “Tests on electric cables under fire conditions on a single vertical insulatedwire or cable”.For enhanced fire performance, special PVC sheath compounds are available, e.g.Reduced Propagation (FR-PVC) and Reduced Propagation &low Hydrochlochloric acid gas emissions(FRLHCL) PVC compounds can be offered as a sheathing material.PVC and XLPE insulated armoured cables with FR, FRLHCL bedding and sheath will pass the testrequirements under category C of IEC 60332 Part 3 specification for “test on electrical cables under firecondition on bunched wires or cables”. For IEC 60332 Part 3 categories A and B, meeting the specificationdepends primarily on the type, size and number of cables in the bunched cable installation that make upthe total volume of non metallic components.Please seek advice from our Technical Department for specific installations.Halogen Free Flame Retardant (HFFR), Low Smoke & Fume (LSF)and Low Smoke Zero Halogen (LSOH, LSZH or LSHF).BICC Cables is manufacturing a dedicated cable called HFFR, which is Low Smoke, Low toxic emissionand low Fume.This cable is specially installed where fire and its associated problems-the emission of smoke and toxicfumes- offer a serious potential threat. HFFR compound is free from halogen (fluorine, chlorine and bromine).BICC Cables can provide the customer with this type of cables that: Are manufactured to BS 6724. Have minimum limited oxygen index (LOI) is 32 % for bedding and over sheath (measured as perBS 2782 / ISO 4589 - A-IV). Have low HCL emission. Have acidic gas evolution of less than 0.5 % ( to BS 2782 ). Comply to IEC 60332 -3 (Cable construction and design should be agreed by BICC Cables).Please refer to BICC Cables technical department for advice about the subject.13

INTRODUCTION4.0 INSTALLATIONAll the cables described in this publication can be used outdoors, but some reservations are necessaryconcerning cables without a metal sheath for direct burial e.g. Unarmoured cables are not recommended for laying direct in the ground. Cables for laying directly in the ground particularly in sustained wet conditions should have extrudedbedding. For installation where there is water logging, or where it is likely to occur, advice should be obtainedfrom our technical department.Other important factors to be taken into account are:4.1 Sheath DamageCare should be taken to ensure that the oversheath is not damaged during installation. This is especiallyimportant where aluminium armour is used since ingress of moisture could lead to corrosion and loss ofearth continuity.4.2 Minimum Bending RadiusCables should not be bent during installation to a radius smaller than that recommended below. Whereverpossible larger radii as should be used.Type of CableOverall Diameter (D)Circular copper conductors, unarmouredCircular copper conductors, armouredShaped copper or aluminium conductors,armoured or unarmoured(mm)Minimum Internal Radius of Bend10-25 mmAbove 25 mm4D6DAny6DAny8D4.3 ConnectorsFor PVC compression or soldered connectors may be used.For XLPE insulated cables, it is recommended to use compression type connectors since the use of solderedconnectors would limit the maximum short circuit temperature of the cable to 160 OC, and consequentlyreduce the final short circuit current by approximately 30 %.4.4 Overhead TerminationsUltra Violet resistant sleeving or taping should be provided on PVC insulated cores to avoid degradationdue to exposure to sunlight.16

INTRODUCTION5.0 CURRENTRATINGS5.1 Source of DataThe maximum sustained current rating (AC) for copper and aluminium conductor cables given for PVCinsulated cables, in this publication are based, where applicable, on ERA report 69-30 Part Ill(Sustained Current Ratings for PVC Insulated cables).For XLPE insulated cables, the current rating in this publication are derived from the latest issue of ERAreport no. 69-30 part 5, which is based upon IEC 287.All other current ratings have to be calculated by agreed formula and methods in IEC 287 and/or the IEEwiring regulations 18th Edition (BS 7671).Current rating or unrmoured cables are based on IEC Publication 364-5-523 (1983) and IEE WiringRegulations 18th Edition.In the case of single core cables, ratings for various installation conditions have been given. Where thecables are armoured, these are based on the assumption that the non-magnetic armour will be solidlybonded at both ends of the cable run. It should be noted that Regulation 521-02 of the 18th Edition o the IEEWiring Regulation prohibits the use of single core cables with steel wire on AC systems.All the current ratings given in data tables are or single circuits, thermally independent of other circuits orany other heat source and on the basis of the standard conditions of installation given.For other ambient or ground temperatures, depth of laying and soil factors given in data tables.5.2 Installation EnvironmentThere are three main installation conditions that affect the current rating of a cable and these are:1. Cables laid directly in the ground.2. Cables laid in ducts.3. Cables laid in free air.Current ratings for PVC and XLPE insulated cables are listed in the relevant tables in data tables and referto standard conditions of installation, for single circuits, as detailed in ERA report 96.30 part 3 and part 5,for ground and duct installation. For installation in air, values are relevant to IEE wiring regulations(18th Edition).For other ambient or ground temperatures, change in depth of laying, soil thermal resistivity or number ofgrouping cables, the current rating must be multiplied by relevant rating factors Listed in data tables.18
5.3 IEE Wiring Regulation 18th edition - Requirement for CablesThe IEE wiring regulations for installation and selection of cables cannot be approached in isolation fromthe other equipment in the installation. In particular the devices providing protection against overload, shortcircuit and shock by indirect contact and overheating of protective conductors during an earth fault affectthe selection of cables.For guidance and assistance, some of the IEE Wiring regulations requirements for cables are giving below:5.3.1 Protection against Overload Current, lEE Wiring Regulation 433The two requirements which determine the sustained current rating required are:(i) The current rating of the cable should not be less than the nominal current or current setting of thedevice providing protection against overload current which in turn should not be less than the circuit current.(ii) The overload protection should operate at not more than 1.45 times the current rating of the cable.The second requirement (ii) is met if the first (i) is satisfied when the protective device is any of the standardfuses or main circuit breakers (MCB) mentioned in the regulation, except rewirable types of fuse toBS 3036.With fuses to BS 3036 the current ratings of the cable should not be less than 1.38 times the fuse rating tosatisfy (ii).5.3.2 Protection against short circuit, IEE wiring Regulation 434The cable has to have adequate short circuit capacity for the current let through by the device providingshort circuit protection for the time it will flow.The formula in section 434-03-03 is that used cable makers to give the short circuit ratings in their publication.If the device providing protection against short circuit is the same as that providing protection againstoverload and, therefore, has a rating not higher than the rating of the cables, the short circuit capacity of thecable will automatically be adequate, there is no need to check.5.3.3 Protection against indirect contact by interruption of supply,IEE Wiring Regulation 413Protection against shock due to contact with exposed conductive parts of equipment during a fault to earthis deemed to be provided if disconnection due to flow of the fault current through the protective device willoccur, either:Within 0.4 seconds for final circuits supplying socket outlets or within 5 seconds for final circuits supplyingfixed equipment.Regulation 413 gives values of earth fault loop impedance which satisfy these conditions when the standardtypes of protective device are used.Cables make the major contribution to earth fault loop impedance, but the impedance of the supply externalto the installation has to be taken into account.19
INTRODUCTION5.0 CURRENTRATINGSIt is not possible to say what maximum length of standard cables may be used in the installation withoutexceeding the requirements for earth fault loop impedance in the absence of information on the externalimpedance for the particular installation.5.3.4 Cross section areas of protective conductors IEE WiringRegulation 543Regulation 543 explains how the cross sectional area of the circuit protective conductor should be calculatedto avoid it overheating during a fault to earth. Again the required depends on the characteristics of thedevice providing protection against short circuit.The steel wire armour standard cables to IEC 60502 (PVC) or BS 5467 (XLPE) provides the required area,or more, when the protective device is one of the standard fuses or MCB’s with a rating not higher than thecurrent rating of the cable (assuming disconnection within 5 seconds).For most of the cables the armour is still adequate when the fuse rating is one or two steps, or even more,above the current rating of the cable, the range being greater or the small sizes and 4 core cables than forthe larger sizes and two cores cable.20
6.0 VOLTAGE DROPVoltage drop is normally only of importance for cables of voltage rating 0.6/1 KV or below. If the insulationis to be in compliance with regulation 525 of the 18th Edition of the IEE wiring regulations, it is stipulatedthat the voltage drop within the installation should not exceed a value appropriate to the safe functioningof the associated equipment in normal service. The requirement is deemed to be satisfied if the voltagebetween the origin of the installation (usually supply terminals) and the fixed current using equipment doesnot exceed 4% of the nominal voltage on the supply, disregarding starting conditions.(Note Diversity can be taken into account when calculating the voltage drop).Since the actual power factor of the load is often not known, the most practical approach to the question ofvoltage drop is to assume the worst conditions, i.e. where the phase angle of the load is equal to that of thecable. The voltage drop values in the tables have been based on this assumption. For conductor sizes upto and including 120 mm2 the figures provided apply this with sufficient accuracy where the power factorlies between 0.6 lagging and 1.0 and for large cables where the power factor of the load does not exceed0.8 lagging. Where the phase angles of the loads fall outside this range, the voltage drop deduced from thetables may be unduly conservative and more exact methods of calculation should be employed.The value of voltage drop for 0.6/1 KV rated cables are given in the current rating tables in datatables.In those cases where the actual current differs greatly from the tabulated current rating, the results obtainedfrom the table are only approximate; for a more accurate assessment allowance should be made for thechange in conductor resistance with operating temperature.(Further information can be gained from the Technical Department of BICC Cables).When current flows in a cable conductor there is a voltage drop between the ends of the conductor whichis the product of the current and the impedance.The following equations should be used to calculate the voltage drop:A. Single phase circuit.Vd 2ll ( R cos Ø X sin Ø )Vs. Three phase circuit.Vd 3 ll ( R cos Ø X sin Ø )VWhereVd : Voltage drop VI: Load current AR: AC ResistanceΩ/KmX: ReactanceΩ/Kmcos Ø : Power factorl: Length kmX w L 10-3Ω/KmL from tables21

7.0 Short Circuit RatingsWhen cables are subjected to temperatures higher than those permissible for continuous operation theymay suffer damage. Therefore, in installation, where there is a possibility of the cables being overloadedby mistake or accident, cables should be selected having regard to the characteristics of the device usedor protection against excess current, so that the effects of overloading are limited to a degree tolerable or arelatively short period of operation. Design criteria and requirement for such conditions are detailed in the18th Edition of the IEE Wiring Regulation.PVC Insulated CablesXLPE Insulated CablesThe values of fault current given in the table beloware based on the cable being fully loaded at thestart of the short circuit (conductor temperature70 C) and at a final temperature of 160 C forconductors up to 300 mm2 and 140 C for sizesabove 300 mm2.The values of fault current given in the table beloware based on the cable being fully loaded at thestart of the short circuit (conductor temperature90 C) and at a final temperature of 250 C. It shouldbe insured that the accessories associated withthe cables are also capable of operation at thesevalues of fault current and temperature.7.1 Short Circuit Ratings for XLPE & PVC InsulatedCables Copper ConductorPVC Insulated CablesCopper ConductorXLPE Insulated CablesCopper ConductorShort Circuit CurrentRating 1000 AShort Circuit CurrentRating 1000 ADuration of Short circuit (Sec.)Duration of Short circuit (Sec.)Conductor Area(mm2)0.20.51.02.03.0Conductor 37.563021518090625123
