35kV VCB

1.high precision, high capacity
2.simple, safe, reliable

 The outdoor products for high-voltage switching equipment, applicable to 40.5 kV transmission system, the role of a sub, a load current, overload and short circuit current use, especially in breaking an important and frequent load operation of establishments

Main Features:

      simple, safe, reliable, long-lived (10000). New insulation materials used in insulation. And the level of a home-and other structures. The overall structure of stainless steel products, hot dip galvanizing support, no corrosion phenomenon. I used CT19BW-allocation-type spring operation, current transformer with high precision, high capacity, variable ratio, multiple-class features.
