HY5WZ（Picture：HY5WZ-17/45TL ）-- Serial Power Station Type Arresters with Thermo-Explosive Disconnectors are mainly used in the voltage system with corresponding voltage class to prevent AC electric equipment of power plants and transformer stations from damages of switching overvoltage and atmospheric overvoltage. When there is larger fault current with arresters, disconnector operates to make fault phase arrester to disconnect with ground wire and there is also obvious breaker point so that fault point can be found quickly for examination and repair.
