Product Description

Hengfengyou High Quality ZW8-12G / 630-20 outdoor high voltage vacuum

circuit breaker with manual tape isolation


Model ZW8-12 outdoor high-voltage Column Vacuum Circuit Breaker is an outdoor high-voltage

switchgear with rated voltage of 12KV. It is mainly used in the distribution system of urban network

and rural network. The outer insulation is made of silicone rubber material with reliable insulation

and strong anti-pollution ability. Zw8-12 vacuum circuit breaker is equipped with Spring Energy

Storage Operation Mechanism, which can be operated manually, electrically and remotely.

The isolation switch can be installed on the side of the circuit breaker to form an outdoor high-voltage

vacuum circuit breaker combined with an outdoor high-voltage isolation switch. According to the

requirements of users, AC high-voltage vacuum auto-recloser, auto-sectionalizer, self-operated power

supply, external high-voltage transformer structure, built-in. Zw8a-12 is composed of ZW8-12 circuit

breaker and isolator. It is called combined circuit breaker and can be used as sectional switch.
