40.5KV Vacuum interrupter for indoor circuit breaker VTD546GF

Vacuum Interrupter (V.I) is a core part that composes the breaking part of high-voltage VCB.

Generally, it is a satisfactory conductor to supply power and it promptly interrupts the current in case of an overload and short circuit faults to ensure the insulation.

It is the most ideal, arc-extinguishing device.

 

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’s annual production capability is 500,000 number of MV vacuum interrupter. It is a leading vacuum interrutper manufacturer in China.

 

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.
