SF6 GAS LOAD DISCONNECTOR

Active sections of the load disconnector; Inside the body insulated with epoxy resin, there is SF6 gas preserved according to the sealed pressure system, it has 3 poles and 2 positions. Due to the fact that the separator body consists of one piece, the joint surfaces that will cause gas leakage are minimized, and the possibility of SF6 gas leakage is eliminated. The earthing switch, which ensures the safety of the operating personnel, is designed with the capacity to close on short circuit in accordance with the standards and air insulated outside the epoxy body. There is a mechanical interlock between the load disconnector and the earthing switch to eliminate the possibility of erroneous manoeuvring.
