Overview
ZW32-12 Outdoor vacuum circuit breakers is the outdoor distribution equipment of 12kV rated voltage, three-phase AC 50Hz,mainly applied to breaking and closing the loading current, overload current and short circuit current of electric power system. Available for protecting and controlling transformer substation, industrial and mining enterprises, frequently operations in countryside of electric distribution, also to be the subsection switch of power system, after installing controller, can make distribution network automatic.
The normal conditions:
1. Ambient temperature: max +40掳C min -15鈩?Storage and transportation under -30鈩?is allowed);
2. Altitude: 鈮?000m锛?/span>
3. Relative humidity: daily average relative humidity: 鈮?5%; monthly average relative humidity:鈮?0%;
4. Daily average saturated vapor pressure: 鈮?.2kPa; monthly average value :鈮?.8kPa;
5. Earthquake intensity: 鈮? degree;
6. The installation site should be no fire, explosion, serious pollution, chemical corrosion and violent vibration.
Customers should contact with supplier if the products is used over GB/T11022 normal environment.
