LW36-40.5 Outdoor AC 50HZ sulfur hexafluoride circuit breakers for three-phase power system of outdoor equipment, forindustrial and mining enterprises, power plants and substations for control and protection. The product can be frequentoperation can be used as contact breakers and meet the capacitor, circuit breaker with reactor group. Containing a cuπent transformer for measurement and protection, can directly replace SW2-35-type breaker, with various models of transition support alternative multi-oil circuit breakers, 35kV power system is the ideal non-oil circuit device.
Note: The circuit breaker in the hot standby state, the fracture City Road side of the arrester must be installed.
LW36-40.5 cirrcuit breaker equipped with the CTl4-A type of AC-D C dual-spring mechanism. 1.3 LW36-40.5-type circuit breakers meet the GB1984 "high voltage circuit breakers" standard.
