The Structural features of ZW32-12 Outdoor Vacuum Circuit Breaker（ZW32-12F、ZW32-12、ZW32-12G ）
1. The circuit breaker adopts a three-phase strut structure, which has the characteristics
of stable and reliable breaking performance, no danger of combustion and explosion, maintenance-free, small size, light weight and long service life.
2. The circuit breaker adopts a fully enclosed structure with good sealing performance,
which helps to improve the performance of moisture-proof and anti-condensation, and is especially suitable for use in cold or humid areas.
3. The three-phase pillars and current transformers use imported outdoor epoxy resin
solid insulation, or use indoor epoxy resin outsourcing silicone rubber solid insulation; it has the characteristics of high and low temperature resistance, ultraviolet resistance, and aging resistance.
4. The circuit breaker can be equipped with two-phase or three-phase current transformers
for overcurrent or short-circuit protection, and can also provide current acquisition signals to the intelligent controller; current transformers for metering can be added according to user requirements.
5. The circuit breaker can be equipped with a three-phase linkage isolating switch.
When the isolating switch is open, there are obvious visible fractures, and it has an anti-mistake interlocking device with the circuit breaker body. Only when the isolating knife is completely closed or completely The circuit
breaker can only be operated when it is open. Arrester pillar insulators can be connected together for easy maintenance.
