Outstanding Features Make You Stand Out
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.
VBI type vacuum circuit breaker conforms to national standard GB1984-2003 HV Vacuum Circuit Breaker, JB3855-1996<3.6-40.5kV indoor AC high voltage vacuum circuit breaker>, DL/T403-2000<12kv-40.5kv HV vacuum circuit breaker ordering technical conditions>, and IEC62271-100:2001 high voltage AC circuit breaker relevant regulations.
