Outdoor vacuum circuit breaker product features
This product is an outdoor The high-voltage vacuum circuit breaker used is mainly used to switch the load current, overload current and short-circuit current of Henan, urban and small power systems.
This product uses insulating materials for phase-to-phase insulation and ground insulation, so the insulation performance is very good. It can be applied to various occasions in power distribution systems at and above, and has reliable performance and stable operation.
The product adopts a three-phase common box design structure. The three-phase vacuum arc extinguishing chamber is placed in a metal box, which effectively improves the insulation performance and service life of the product.
This product is combined with an isolating knife switch. It can be used as a segment switch or it can have its own power supply, either built-in or external. Xi'an Tianzheng Electric Power Technology Co., Ltd. supplies spot parameters
