The main circuit unit and running product are coherent in interchangeability.
The operating mechanism can be separated from the whole circuit breaker for convenient and easy maintenance and fix.
No need of adjustment of driving unit; long-acting lubricating, reliable corrosion resistance, and high mechanical stability make low maintenance possible.
We apply German lubricating grease boasting lower starting torsion, stronger anti-aging and oxidation resistance.
Utilizing zinc-nickel alloy plating line with a German process to make sure our corrosion resistance is 5 to 7 times stronger than ordinary zinc-plating process.
This product can easily realize diverse arrangements and combinations to meet functions like expandability and control.
VSG-40.5 series vacuum circuit breaker is a new type of three-phase 50Hz according to the unique design concept and combined with the market demand and development, the rated voltage of indoor switchgear40.5kV, it can be provided to industrial and mining enterprises, powerplant and substation as the control and protection of electrical equipment,and is suitable for frequent operation.
