Product Description
ZW32-12 Outdoor HV vacuum breaker (Recloser, Sectionalizer)
Mostly purpose
The ZW32 outdoor HV vacuum breaker is a kind of outdoor power distribution equipments on rated voltage12kV, 15kV and three-phase AC 50Hz~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 net-works. 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 switching off/on load current, over-load current and short circuit current in power systems. Its vacuum explosion chamber uses patented technique. Its external insulation uses silicon rubber pipes with long life, high reliability and weatherability. 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 simple and has long life up to 2000 times.
