Vacuum Interrupter for Outdoor Circuit Breaker

Vacuum arc extinguishing chamber, also known as vacuum switch tube, is the core component of the high voltage power switch, its main role is to cut off the arc and inhibit the electric current by its high inside insulation performance to avoid accidents.

Wuhan Feite Electric brand vacuum arc extinguishing chamber adopts a corrugated ceramic insulation shell, copper tungsten tungsten carbide alloy materials contact, using advanced one exhuast technology process makes the vacuum interrupter has the advantages of small volume, high insulating level, low closure value, long service lifetime, easy-maintenance, explosion-free, low noise,low maintenance costs, reliable operation and non-pollution etc.. The vacuum arc extinguishing chamber mainly been used in power transmission and distribution control system. It is also can be used in metallurgy, mine, petroleum, chemical industry, railway, broadcasting, communications, industrial high frequency heating power distribution system.

Wuhan Feite Electric vacuum arc extinguishing chamber for outdoor circuit breaker rated voltage is 7.2KV~40.5kV, rated current is 630A~4000A, rated short circuit open fault current is 12.5KA~40kA.
