12KV Outdoor Vacuum Circuit breaker (1)Suit for three-phase A.C50Hz (2)Rated voltage:12KV (3)Rated current:630A

General description:

ZW8-32 Outdoor Vacuum circuit breaker is three-phase A.C 50HZ outdoor high voltage distribution equipment with 12kv rated voltage and below, which can be used for opening and closing loading current, overloading current and short-circuit current. If it is connected with computer remote control system and data wireless transmission terminal etc., the remote opeing and closing function can be achieved. This is the optimum unoil equipment for remarking the town and country’s electric net.

 Application and feature:

It is equipped with CT23 type spring energy-stored operating mechanism. Energy-stored, opening and closing can be achieved by motor or by manual.

Applying ambient conditions:

Ambient temperature should be -40~+40.

The height above sea level should be no higher than 1000m.

Wind pressure should be on more than 700Pa.

It is equivalent to wind speed of 34m/s.

The air filthy should be with in III degree.

Frequently violent vibration should be forbidden.
