Mostly purpose
The zw32 outdoor HV vacuum breaker is a kind of outdoor power distribution equipments on rated voltage 12kv,15kv and three-phase ac50hz~60hz it is used for protecting and controlling distribution systems in transformer substations and industrial and mining enterprises it can also be used for frequently operation in country electric networks.and it can be used as a ring network power supply unit and terminal unit to distribute electric energy,control and protect electric equipments .combining with the disconnecting switch,it can be used as a section switch for seitching off/on load current ,over-load current and short circult current in power systems ,its vacuum explosion chamber uses patented sealing technique.ints external insulation uses asillcon rubber pipes with long life,high reliablity and weatherbility .it is convenient to transport and has a high cost performance ratio.using compact and high reliability spring operating mechanism ,the operating mechanism structure is ismple and has long life up to 20000 times. if using adcanced permanent magnetism mechanisms,it will have more reliable mechanical property,and it can install manual switch on/off mechanisms to switch on/off in the field in need of .matching with controllers,the breaker can be an automatic circult recloser to realize remote contralling,remote measurement,remote signaling and remote regulating .the product’s features:non buring and explosion hazard,non maintenance,smallsize,light weight(less than 100kg)long life(more than 10000times ),safe and reliable,simple operation and installation
