Dry Type TransformersSection 10General InformationTypes QB, QMS, QL600 Volts and BelowGeneral InformationTemperature ClassThe complete family of transformers from GE provide quiet,reliable transformer operation.Industry standards classify insulation systems in accordance withthe rating system shown below.All of the dry-type transformers through 1,000 kVA are UL listedunder the requirements of Standard 5085 and 1561. In addition,each transformer meets the requirements of NEMA ST-20, 1992.Type IP, QB and QMS models are C-UL listed.General-purpose transformers are rated 600 Volts and below forsupplying appliance, lighting, and power loads from electricaldistribution systems. Standard distribution voltages are 600, 480,and 240 Volts; standard load voltages are 480, 240, 208, and 120Volts. The transformer is used to obtain the load voltage from thedistribution voltage. Since no vaults are required for installation,these transformers can be located right at the load to providethe correct voltage for the application. This eliminates the needfor long, costly, low-voltage feeders.AmbientInsulation System Classification Winding Rise Hot Spot40 C40 C40 C40 C55 C80 C115 C150 C Temp. Class10 C30 C25 C30 C105 C150 C180 C220 CAll standard, general-purpose, GE transformers meet all applicableNEMA, ANSI, UL, and IEEE standards.The design life of transformers having different insulation systemsis the same, since the allowable temperature rise of an insulationmaterial system is predicated on a specified life for all insulation.The lower temperature systems are designed for the same life ashigher temperature systems.Sound LevelsConstructionTypes QB and QMSCore and coils are contained within a NEMA 3R nonventilatedweatherproof enclosure. Type QB and QMS units featureencapsulated core and coils.Type QLUnits are enclosed in a NEMA 2 drip-proof painted metal enclosure with natural draft ventilation. The core-and-coil assembly ismounted on rubber isolation pads to reduce noise. Weathershieldkits are available for conversion to a NEMA 3R enclosure suitablefor outdoor service. NEMA 2 and NEMA 3R stainless steel (Type316) enclosures are available up to 150kVA. To specify a stainlesssteel enclosure for an aluminum-wound transformer, substitutethe letter “S” in the fifth character of the GE product number. Forexample, 9T10A1004 changes to 9T10S1004. For copper-woundtransformers, substitute the letter “Z” in the fifth character of theGE product number. For example, 9T10C1004 changes to9T10Z1004. All QL model product numbers begin with 9T7, 9T8,or 9T1.All general-purpose transformers are as quiet, or quieter thanrequired by NEMA ST-20. Average sound levels are warranted notto exceed the values listed for each load rating shown in theadjacent table. Sound characteristics vary between transformersof identical voltage and kVA rating. The range of variation may be4 to 8 decibels.These values apply only to specified test conditions because thecharacteristic of the installation can cause them to be higherunder operating conditions. Where acoustical noise is deemed tobe of unusual concern, proper steps should be taken duringinstallation to minimize audible noise transmission.Sound Levels (Decibels)1 for 150 C Rise ModelskVA0-910 - 5051 - 150151 - 300301 - 500Sound Levels40455055601Measured per NEMA ST-20.Transformer taps compensate for high or low line voltages. Moststandard QL units rated 15kVA through 300kVA and with a primary voltage of 240V or higher have six available voltage taps –four 2.5% taps below the nominal tap and two 2.5% taps abovethe nominal tap. This arrangement provides a 15% range of tapvoltage adjustment. Transformers rated 500kVA and higher havefour available voltage taps – two 2.5% taps above the nominaltap and two 2.5% taps below the nominal tap.10-2GE Products BuyLoggo.abb/industrialRev. 1/19Data subject to changewithout notice
