ZW8-12 series outdoor high-voltage column vacuum circuit breaker is a new type of outdoor high-voltage switchgear with rated voltage of 12KV. It is mainly used for distributing and combining load current, overload current and short-circuit current in urban and rural power distribution systems.
It is an ideal product to replace oil - immersed circuit breaker to realize oil - free. The outer insulation is made of silicone rubber material, which has reliable insulation and strong anti-pollution ability. ZW8-12 vacuum circuit breaker equipped with spring energy storage operating mechanism, manual operation, electric operation and remote control switching and closing operation. An isolation switch can be installed on the side of the circuit breaker to form an outdoor high-voltage vacuum circuit breaker and an outdoor high-voltage isolation switch combination, which increases the visible isolation break and has reliable interlocking operation. According to user requirements, it can cooperate with the corresponding controller to form AC high-voltage vacuum automatic recloser, automatic sectioner, self-provided operating power supply, which is the ideal equipment to realize the automation of distribution network. Adopt high voltage transformer structure external, internal can be. ZW8A-12 is a combination of ZW8-12 circuit breaker and isolation knife, called combination circuit breaker, can be used as a segment switch.
