ZW8-12 adopt vacuum interrupter, air insulation, equipped electric spring mechanism to operate, all this made the product has high arc extinction ability, high short-time breaking times, no fire explosion danger, easy operate. It is a good performance and practicable product.
ZW8-12 breaker main structure adopt three-phase together box type, casing pipe inlet and outlet line, and in the box it is dry air. Electric spring mechanism located in the side of the box, it can be used under most serious circumstance.
ZW8-12 breaker's vacuum interrupter use ceramic package, cup shape and longitudinal magnetic field contactor structure. So it has high ability to cut-off and short-circuit making capacity.
ZW8-12 has small volume, light weight, beautiful outlook. Vacuum interrupter and insulation supporting casing pipe's compact design, outlet line conducting rod outside-feeding silicone rubber, it can be used under serious weather conditions and pollution environment.
