Application
ZW8-12 series adopts vacuum arc extinguishing chamber, air insulation and electric spring operating mechanism, which makes the product have strong arc extinguishing ability, high short-circuit breaking times, no fire and explosion hazard and convenient operation. It is a kind of product with excellent performance. Practical products.
The overall structure of this product adopts three-phase common box type, with casing inlet and outlet lines. The box body is dry coal air. The electric spring operating mechanism is arranged on the side of the box, which can be used reliably under severe environmental conditions.
The vacuum interrupter of this product adopts ceramic shell, cup-shaped longitudinal magnetic field contact structure and copper chromium contact material, which has excellent ability of breaking and closing short-circuit current.
The product has the advantages of small volume, light weight and beautiful appearance. The vacuum interrupter and insulating support sleeve are compact in design, and the outgoing conductive rod is injected with silicone rubber, which can adapt to harsh weather conditions and dirty environment.
