SG (B) 13 type dry-type transformer
SG (B) 13 type dry-type transformer
Product features:
Low loss: the product no-load loss is 30% lower than the SC (B) 10 type product with an excellent energy saving effect, The load loss is more than 10% lower than that of SCB11 type.economic-efficient operation and without maintenance.
Low noise:the product noise level is 10-15 db lower than the existing professional standard JB/T10088-2016 Sound Level of 6-220KVTransformer
Low partial discharge: resin mixture adopts foreign leading-edge mixing method and film type vacuum deaerator to evenly mix the mixture and remove the bubble in the bottom part of mixture.Theproduct has a lowpartial discharge which can becontrolled at 5PC.Both high voltage and lowvoltage coils can be poured in vacuum Ipressure so as to enable a encapsulating of resin insulation and immersion among layers and inter-turns.The poured part has a compact solidity structure with
antiflaming, anti-explosion and environmental protectionfeatures.
Glass fiberandotherrawmaterials ofwinding coilhaveself-extinguishing property and wil not produce arcdueto shortcircuit. Resinwill notproduceharmfulgas under high temperature.
Great mechanical strength: resin with filings can lower the differences of dilatation coefficient, cure shrinkage rate and internal stress as wll as increase the hardness of condensate within the poured area. Precast and fashioned reinforcing materials are placed in the seal coat of epoxy resin which is painted on the inside
and outside surface of high and low-voltage coil, making the structure as compact as the reinforced concrete so that the mechanical strength is greater than epoxy resin which can bear theelectro-dynamic action caused by sudden short-circuit without damage.
