description: 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.
Characteristics: 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. The parameter:
