ZHW1-252

1.General DescriptionZHW1-252 type integrated switchgear with the core parts of dead tank circuit breaker is the newest production of our scientific research, without enclosed bus bar. With the excellences of GIS-252 and H-GIS, the production has not only perfect function, steady performance, compact size, but also simple structure, strong adaptiveness, Also has its own components and integrated, unique modular design .ZHW1-252 composite gas insulated switchgear takes SF6 gas as medium of arc extinguishing and insuletion. It is composed of circuit breaker, current transfomer, 5-position modular isolator / earthing switch, three-position modular isolator /earthing switch, gas insulated pipe, local control panel and so on. It is used for transmission line controling, measurement, protection, isolation and switching of 252kV, 50Hz transmission line.ZHW1-252 composite gas insulated switchgear is totally pursuant to《Gas insulated-enclosed switchgear of 72.5kV and above》GB76742.Tec
