Outstanding Features Make You Stand Out
We play extreme caution to quality and utmost attention to detail, which makes our products so perfect.
We play extreme caution to quality and utmost attention to detail, which makes our products so perfect.
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-12 indoor high-voltage vacuum circuit breaker is an indoor and outdoor switching device used in 12KV power systems. It is used as a protection and control unit for power grid equipment and power design of industrial and mining enterprises. It is suitable for switching loads of different natures and frequent operations. The occasion of breaking short-circuit current for the first time. The product adopts VSG module integrated spring operating mechanism. The primary part of VSG-12 can use a sealed pole to seal the vacuum arc extinguisher and the main conductive circuit parts into a whole, protecting the arc extinguisher from collision, dust and condensation. It has strong environmental adaptability and greatly reduces the cost of the arc extinguisher. operation and maintenance costs
