ZW32-12 outdoor use high voltage vacuum circuit breaker for rated voltage 12K. v,three phase SOIIz system is mainly used to break and make loading current, overloading current and short circuit current of electric distri-bution system in substation, mineral enterprises and furthermore agricultural power networks in order to protect and control the connected equipment.
1.Fully hcrrmctical structure: Able to improve the character of anti moisture and dew, the VCB can be worked in high temperature and high humidity zone, and effectively avoid from corrosion due long term outer atmosphere, compact and rational structure, weight less than 80kgs.
2.Vacuum interrupter: High and secure breaking capacity, low abrasion of contacts, short circuit breaking capacity up t0 20KA.
No flammable and explosive events occur, safety and maintenance free.
3.Outdoor used epoxy resin of enclosure: reinforced the insulation performance caused from moist conditions and anti-corrosion from ultraviolet radiatipn, meet with the requirement of working high climatic proof and sever ambient conditions
4.Operating mechanism: New style, simple, secure action, mechanical life up t0 10000 0perations. Manual operation, electrical operation and remote control available.
5.Multi-function: Two phases of three phase outdoor CT may be equipped for control and measure. Operated with controller remote control and monitoring can be realized.
The operating environmental conditions:
1.Altitude: not more than 2000m, the plateau is not higher than 4000m.
2.Environment: -30 °C ~40 °C, -50 °C low temperature type circuit breaker limit.
3.Relative humidity: daily average value not more than 2.2kpa, on average less than 1.8 kpa.
4.Earthquake intensity: less than 8.
5.Can according to user requirements increase electric anti jump.
6.Wind: ≤ 700Pa (equivalent to the wind speed 34m/s)
7.Air pollution level: common grade III, special grade.
8.Available in more than GB/T11022-1999 specified above normal environmentalconditions, the user can be resolved in consultation with the manufacturer.
