Low loss:the product no-load loss is 20% lower than the Sc (B) 11 type product with an

excellent energysaving 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- 2004Sound Level of 6- -220KV Transformer

Low partial discharge:resin mixture adopts foreign leading-edge mixing method and film type

vacuumdeaerator to evenly mix the mixture and remove the bubble in the bottom part of mixture.

The product hasa low partial discharge which can be controlled at 5PC. Both high voltage and low

voltage coils can bepoured in vacuum pressure so as to enable a encapsulating of resin insulation

and immersion amonglayers and inter-tums. The poured part has a compact solidity staicture with

anti-flaming, anti explosionand environmental protection features.
Glass fiber and other raw materials of winding coil have self- extinguishing property and will not

producearc due to short circuit. Resin will not produce harmful gas under high temperature.
