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-24 Series of Indoor high Voltage Vacuum circuit breaker with embedded poles is three phase A.C 50Hz indoor power distribution equipments with the rated voltage of 24kV. It’s used for protecting and controlling the electrical equipment in the fields of industry&ming enterprise , power plants and substation.
The main conductive circuit of this type vacuum circuit breaker uses embedded pole, matched with Modular organization and Integrated energy storage handle. The overall layout is reasonable, perfectly with brevity and really realize the free-maintenance and longer mechanical &electrical life.
