220KV 3Ph Live Tank SF6 Gas Circuit Breaker

LW Series self-energy SF6 Circuit Breaker is a three-pole/single-pole AC 50Hz/60Hz outdoor high voltage power transmission equipment for the division of the rated current, fault current or conversion lines, transmission and distribution system for protection, control and operation can be opening, closing and fast automatic reclosing operation. The circuit breaker using the latest design principles, has a simple structure, small size, low supplies, the energy needed to operate a small, high reliability, easy installation, low noise characteristics. Is my company developed a new generation of high voltage SF6 circuit breakers.
