1NOTICEAs this catalogue is not intended to cover all of LIBAN CABLES SAL possibilities inHigh Voltage cables manufacturing, the hereafter listing of the types of cables is notrestrictive but only indicative of the main and most current types we manufacture.On the other hand, our specification sheets are inspired mainly from :- Iternational Commision Specification ( IEC 840 ).- Association of Edison Illuminating Companies (AEIC CS7-93).- Electricité de France Standards (HN 33-S-52) and (HN 33-S-53).- Electricité du Liban current specification.Whereas, in fact, some High Voltage cables may require special conception, fully withinthe capabilities of LIBAN CABLES SAL, ISO 9001 certified, precisely because inposition to conceive / tailor your special needs.That is why, while consulting this catalogue, it is important to take into account that anycombination or change of the constructional details mentioned in this catalogue remainfeasible, on base of special conception / development, matching any special or differentspecifications.Finally, and within our policy of constant improvement, we reserve the right to alter anypart of the information contained in this publication without incurring any obligation.In all cases this brochure being only indicative, and unless expressly agreed upon, itcannot be considered by any mean as contractual document.7
2INTRODUCTIONDevoted to the manufacturing of electric and telecomcables, Liban Cables is the first and largest supplier inLebanon and a leader in the Middle-East region.Liban Cables was founded in 1968 by a group ofLebanese industrialists backed up by the technicalassistance of two international leading firms :- Les Cables de Lyon - France (became ALCATELafterwards)- Phelps Dodge - U.S.A.Staffed with qualified engineers and highly skilledtechnicians, our plant is located in Nahr-Ibrahim at 30Km from Beirut, where cables are designed andmanufactured according to all internationalspecifications : IEC, AIEC, VDE, UTE, BS and otherson customer request.Early after its foundation, Liban Cables has become themajor supplier of the Lebanese market in both the publicand private sectors. The product range of Liban Cablescovers all electric cables up to 245 KV, communicationcables (copper and optical fiber) in addition to a widevariety of special cables manufactured on customerrequest.High quality cables, continuous developments of theproduction range, direct and fast shipments havecontributed in rendering Liban Cables an importantexporter for many countries on the three limitrophecontinents (Asia, Europe & Africa). Liban Cablesproducts are particularly appreciated by administrationsand international contractors operating in the region andseeking reliable and direct supplies of power andcommunication cables.8
3 QUALITYStep by step, from raw material to final product, quality constitutes a major concern toLiban Cables.Raw material are continuously and repetitively tested from trial orders till the last batchreceived afterwards.In addition to the final tests carried out on finished products, work in process is alreadytested within two simultaneous procedures :- A built in quality control system carried out by the production itself at any step of workin process.- A parallel and contradictory procedure is also carried out on the same stages andproducts by independent inspectors reporting to the quality control service.End users and/or third part inspection authorities are also constantly commissioning thefinished products and assessing the strict conformity to ordered specifications.In fact, our ISO 9001 certification stated in Feb 1997 by the International CertificationNetwork (EQNET) is certified by the French Association for Quality Assurance (AFAQ),the well known rigourous and independant accredited European assessor. Thiscertification, under reference AFAQ Nº QUAL / 1997 / 7034, confirms the soundness andthe performance of the Quality System we apply for the Design, the Development, theManufacturing and the Marketing & Sales of all our products.4 RECOMMENDED ORDERING PARAMETERSBased on your specific context of usage, we remain ready to design the exactly suitablesystem (Cable & Accessories), on base of worldwide proven standards, as well as on baseof special conception / development, carried out in cooperation with our TechnicalAssistance pourveyor, Alcatel Cable France.9
5GENERALITIES5.1 - TABLES OFCONSTRUCTIONAL DATA, ELECTRICALCHARACTERISTICS AND CURRENT RATINGSGeneral presentationThe following tables are given as a guide to engineers involved in the study of networklinks, admissible current ratings as well as defining and selection of cable types.The tables are not the definitive list of Liban Cables range but a simple solution guide tothe most common cables used. Should a problem be unresolved by the tables then a casestudy could be carried out by Liban Cables, on base of specific request to reach the mostappropriate tailored conception. In this event, please contact: Liban CablesTwo screen options for cables in the High Voltage 66 KV to 225 KV range are given, forcopper or aluminium conductors:1 - Lead sheath screen2 - Copper or aluminium wire screenLaying and Earthing conditionsWe have retained only these most common configurations (see chapter 5.2 for otherlaying conditions):Trefoil formation Laying Laying depth Thermal conditions- Case N 1*- Case N 2* Axial distance Earthing method- S 630 mm2- S 630 mm2Buried cablesd 1.3 mFlat formationBuried cables Cables in aird 1.3 mCables in airρT 1.0 C.m/WT 30 CT 20 CρT 1.2 C.m/WT 30 CT 50 CρT 1.0 C.m/WT 20 CρT 1.2 C.m/WT 30 CClose formationcontinuous earthing(with circulating currents in the metallic screen)T 30 CT 50 C2 x outer diameter}at one point only or perfect cross-bonding(without circulating current in the metallic screen)at one point only or perfect cross-bonding(without circulating current in the metallic screen)*ρT: Soil thermal resistivity - T: Soil or air temperature.Admissible current ratingsAdmissible current ratings given in the following pages are against the conditions givenin the above table, for one circuit in operation with a load factor of 100%, in accordancewith IEC Publication 60287.10
