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.
Summary:
VS1-24 series of indoor high voltage vacuum circuit breaker with common insulated cylinder is three-phrase A.C. 50 Hz indoor power distribution equipment with the rated voltage of 24KV. It’ s used for protecting controlling the electrical equipment in the fields of industry and mining enterprise, power plants and substation.This type vacuum circuit breaker conforms to national standards and the stipulation of IEC standard, the capability reaches grade of M2-E2-C2.
The product adopts composite insulation way,spring charged operation and rod push mechanism,with the characteristics of small volume, compact design and reliable operation. It can easily match with the switchgear and meet the “Five Preventions” demands.
This kind of vacuum circuit breaker can be used for many kinds of switchgear like KYN28-24(GZS1). This series of products include: VCB truck isolation truck and Fuse truck, etc.
