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.
