Product Description
LW34-12 10KV outdoor high voltage SF6 circuit breaker is a new outdoor high-voltage electrical arcing and SF6 gas as insulating medium. The operating mechanism points manual storage spring mechanism, motor energy storage spring mechanism, DC electromagnetic actuator three, all kinds of fish breaker actuator perfect combination of body as a whole. This product compared to other fish 10kV class outdoor circuit breakers, has a simple structure, high arcing and insulation performance, small operating power, high ratings, long life and no maintenance cycle and other significant advantages. Use of this product will not only reduce the area. Reduce project cost and eliminate the risk of fire, and can greatly improve the reliability of the power system.

The vacuum circuit breaker comprises a steel arc chamber in the center-symmetrically arranged ceramic insulators. The pressure inside the vacuum interrupter is maintained below 10^-4 torr. The material used for current carrying contacts plays an important role in the performance of the vacuum circuit breaker. The alloys like, Copper-bismuth or copper-chrome are the ideal material to make VCB contacts.
