High voltage vacuum circuit breaker (HV VCB) is a critical component in modern electrical systems, designed to interrupt circuits in the event of faults, overloads, or short circuits.

Unlike traditional methods, Vacuum Circuit Breakers provide:

 Efficient arc extinguishing

-The vacuum environment can block ionization, rapidly extinguish arcs in microseconds, quickly restore insulation, and accurately cut off current.

-Low arc energy can reduce thermal damage and protect equipment life.

High reliability

-No need for complex mechanical components, low failure rate, and can withstand high-frequency switching operations.

-Resistant to extreme environments and stable performance.

Low maintenance cost and long service life

-No need to replenish gas/liquid, low transportation and maintenance costs.

-Durable design, with a lifespan of several decades.

Lightweight

-Small size, suitable for narrow spaces such as switchgear and substations; Lightweight, easy to install and transport.

 Inherent safety features

-No flammable media (suitable for high-risk scenarios such as petrochemicals and mines).

-Extremely low electromagnetic interference.
