"JECSANY" is a professional China various medium and high voltage product provider which supplies vacuum circuit breakers, auto reclosers, switchgear, surge arresters, dropout fuses, polymer/porcelain insulators, power tools, power accessories, OPGW/ADSS, distribution transformers, etc. And be able to provide one-stop service for new and old customers, including product development, design, manufacturing, transportation, installation, and after-sales service.
High voltage vacuum circuit breakers can be classified in the following ways
a) According to the arc extinguishing device, the arc extinguishing medium can be divided into:
(1) Oil circuit breaker (less oil circuit breaker and more oil circuit breaker);
(2) Air circuit breaker;
(3) Magnetic blowing circuit breaker;
(4) Vacuum circuit breaker;
(5) Sulphur hexafluoride circuit breaker;
b) According to the nature of the operating mechanism, it can be divided into:
(1) Electrically operated structural circuit breaker;
(2) Hydraulically operated structural circuit breaker;
(3) Pneumatically operated structural circuit breaker;
(4) Spring energy storage operation structure circuit breaker;
(5) Manually operate the structural circuit breaker;
c) According to the installation location, it can be divided into:
(1) Indoor circuit breaker;
(2) Outdoor circuit breaker;
(3) Explosion-proof circuit breaker;
The vacuum circuit breaker has the characteristics of small contact opening distance, short arcing time, and slight burn of the contact when breaking the fault current. Therefore, the operation energy required by the vacuum circuit breaker is small and the action is fast. It also has the advantages of small size, light weight, low maintenance workload, fireproof, explosion-proof and low operating noise.
Vacuum circuit breaker is suitable for power distribution and control equipment, especially for frequent operation, controlling high-voltage motors, matching capacitor banks, and protecting large-scale silicon rectifiers and other high-voltage electrical equipment.
"JECSANY" Vacuum circuit breakers have stable quality and have third-party IEC test reports, and the products are exported to North America, Southeast Asia, South Africa, South America, the Middle East and other global markets. OEM customization can also be made according to the drawings or samples provided by customers.
