Product intruductionLW36-40.5 outdoor self energy HV AC SF6 circuit breaker is an outdoor three phase HV AC equipment used in electricity grids with altitudes of no greater then 3000m, environment termperature of no less then -30ºC, local pollution classes of no higher than Class IV, and AC 50Hz with maximum voltage of 40.5kV. It is suitable for the control and protection of HV supply and tranformation lines in power plants, transformer, stations, and industrial and mining enterprise. It can also be used as a connection circuit breaker.
LW36-40.5 self energy HV SF6 circuit breaker is equipped with advanced hot-expansion plus auxiliary pressure gas self-energy arc extinguishing technology and matched with new type spring actuating mechanism. It has features such as long electrical endurance, small operating power, high electrical and mechanical reliability, high technical parameters, and moderate price. It is the first choice product for current 40.5kV electircity grids.
FeatureIts main performance features are as follows:
1. High rated parameters
2.High electrical reliability
3.High reliability of operating mechanism
