Detailed Product Description

    ZW-40.5/2000-31.5 Outdoor HV Vacuum circuit Beaker is available in power T&D system with rate voltage of 35KV, rated current of 1600A, Ac three phase and 50HZ. It could be used in industrial enterprises and mines, power plant and substation for protection and controlling, as well as interconnection circuit breaker. This also available in places for frequent operations.

      This product is a kind of outdoor HV vacuum circuit breaker. Its overall structure is a kind of knob and tube type. The vacuum

 arc extinguishing room is equipped in upper porcelain tube and a kind of sliding contactor, which results in a lower circuit

 resistance and good conductivity.

    1. The dimension of a new designed arc extinguishing room is smaller, with a higher current breaking capacity, a higher insulation level and a higher arc extinguishing ability, etc.

    2. A spring operation mechanism, model CT17-1VB, is equipped in the operation mechanism, with advantage of a smaller operation power, easy operation and a longer service life, etc.

    3. SF6  was filled in the porcelain knob and tube, so condensation could be avoided because of a higher temperature changing and the insulation level of the circuit breaker shall be greatly increased.

    4. One to 6 pieces of individual current transformers could be equipped in this product. So this kind of product can satisfy an accuracy requirement at varied current level. And there is not any interference between primary single wiring and secondary wiring.

    5. Typical technical characters are as follows, rated current:2000A, rated voltage 40.5KV, rated short circuit breaking current:31.5KV.

    6. Application range is wide (below 3000m of sea level).

    7. Service life shall be higher than 10000 times.
