Three Phase Automatic Overhead 27KV Recloser

 

General

The ZW32 outdoor HV vacuum breaker/Recloser 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.


    Salient feature
1.  Epoxy resin solid insulation,no oil and SF6,harmless to environment
2.  Vacuum breaking and longitudinal magnetic-field arc extinction,steady and reliable
3.  Outdoor special epoxy resin,ultraviolet ray withstand,flashover proof and aging again
4.  CTB-S spring operating mechanism is widely used.The mechanical life is 10000~3000 times
5.  With compact structure,small size and light weight.It is easy install and transport it
6.  Dealt case body,no corrosion,outline remains good looking long(Choose stainless steel case body)
7.  Intelligent computer controller,provides miscellaneous functions
8.  It realizes supervisory control,monitoring and SCADA by matching FTU
