ZW43-12G 12KV 630A Outdoor High Voltage Vacuum Circuit Breaker Switchgear

Three-phase pillar type fully enclosed structure with high sealing performance:
1. The breaking performance is stable and reliable, there is no danger of burning and explosion, maintenance-free, small size, light weight and long service life.
2. It has strong moisture-proof and anti-condensation properties, especially suitable for use in cold or humid areas.
3. Imported materials have good insulation performance, high temperature resistance, UV resistance and aging resistance.
Efficient and reliable miniaturized spring operating mechanism:
1. The power of the energy storage motor is small, the energy consumption of opening and closing is low, the mechanism transmission adopts the direct transmission mode, the number of parts is small, and the reliability is high.
2. The operating mechanism is placed in a sealed box, which can effectively prevent corrosion and improve the reliability of the mechanism.
Convenient and flexible control and free combination performance:
1. Manual opening or electric opening and closing and remote control operation can be used.
2. It can be matched with intelligent controller to realize power distribution automation, or combined with recloser controller to form automatic recloser and sectionalizer.
3. Two-phase or three-phase current transformers can be installed for over-current or short-circuit protection.
4. It can provide the current acquisition signal for the intelligent controller, and can install the current transformer for metering according to the user's requirements.
5. The three-phase linkage isolating switch can be taken out, with the anti-mistake interlocking device, and the arrester pillar insulator can be connected, which is convenient for maintenance.
