Pole - Mounted Outdoor Column High - voltage Vacuum Circuit Breaker

General
The vacuum circuit breaker on the ZW32 column is an outdoor 11kV and 50Hz AC power distribution equipment, which is mainly used to shut down and turn over current and short circuit current in power system. Can be used as a power distribution line, branch, ring network, ring network, industrial and mining enterprises, residential quarters, construction sites, such as a sub switch.
Product Features

The product uses the latest intenational design concept and epoxy resin encapsulated silione rubber APG insuation technology as welll as precision processing technology. The technology is in the domestic

leading level.

The features are as follows:
1.The product adopts three phase pillar structure, compact design, stable and reliable breaking performance, no fire and explosion hazards, maintenance-free, small size, light weight and long service life.
2. The circuit breaker can be equipped with integrated disconnector, and has reliable mechanical interlock between disconnector and circuit breakers, to prevent misoperation.
3. The circuit breaker is fuily enclosed structure with good sealing performance, high anti-moisture, anti-condensation propertes specially suitable for cold or wet areas.
4. Three- phase column and CT are adopted imported outdoor epoxy resin solid insulation material casting. It has the features of high temperature resistance, UV resistance, anti-aging characteristics, and it can ensure long-term outdoor safety.
5 The circuit breaker uses the small size spring operation mechanism, low enery consumption during open-close. lts transmission adopts direct drive method, and less open-close parts,high relability. lts operation mechanism is sealed in the mechanical box ,which solves corrsion problem of switch parts so as to improve the reliability of circuit breaker.
6. The open-close operation of the circuit breaker can use manual operation, and motor operation.It can be equipped with controller to realize distribution automazation as well as combined with recloser controller as automatic recloser.
7. The circuit breaker can be equipped with two-phase, three- phase and zero-sequence CT to provide data analysis for overcurrent automatic release protection and smart controller.

Environmental Conditions

1. Altitude: ≤1000m; if applied in special conditions, it is designed to 2000m to 4000m to meet the requirements of different altitudes.

2. Ambient temperature: -15℃~+40℃;

3. Wind speed≤35m/s;

4. It is placed in the places without violent vibration
