Product features:

The high voltage coils use Nomex-410 insulating material, the VPI vacuum pressure impregmating international advanced equipment solventless insulation paint, sealing with high strength grade H insulation materials, and high temperature curing, ensure no partial discharge under operation condition.

High voltage coils use high mechanical strength, good heat dissipation conditions (high and low voltage winding all use 200C and above, long-term use of Nomex insulating materials) continuous structure, avoid the multi-layered cylindrical coil layer of high voltage, thermal dissipation, easy thermal breakdown and the disadvantage of low mechanical strength, thereby improving the reliability of product.

Product performance according with GB1094.11-2007, GB/T10228-2008, IEC60076-2004.
