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.
The operation mechanism of VBI-24 side mounted type vacuum circuit beaker is used spring to storage energy,which can be operated by two ways,manual or electrical.The characteristics are accordance with GB1984-89 <AC High Voltage Circuit Breaker>,JB3855-96<10kv Indoor High Voltage Vacuum Circuit Breaker General Technical Specifications>,Relevant Provisions of IEC56 standard.
