SCB13 Dry-type Transformer

Product features

Low loss: the product no-load loss is 20% lower than the SC (B) 11 type product with an excellent energy saving effect, economic-efficient operation and without maintenance.

Low noise: the product noise level is 10-15 db lower than the existing professional standard JB/T10088-1999 Sound Level of 6-220KV Transformer

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. The product has a low partial discharge which can be controlled at 5PC. Both high voltage and low voltage coils can be poured in vacuum pressure 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 anti-flaming, anti-explosion and environmental protection features.

Glass fiber and other raw materials of winding coil have self-extinguishing property and will not produce arc due to short circuit. Resin will not produce harmful gas under high temperature.

Great mechanical strength: resin with fillings can lower the differences of dilatation coefficient, cure shrinkage rate and internal stress as well 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 the electro-dynamic action caused by sudden short-circuit without damage.
