product description

 It adopts vacuum interrupter, 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 easy operation. It is a product with excellent performance and strong practicability.

 The overall structure of this product adopts a three-phase common box type, the casing enters and exits the line, the dry air is in the box, and the electric spring operating mechanism is arranged on the side of the box, which can be used reliably under harsh environmental conditions.

 The vacuum interrupter of this product adopts ceramic shell, cup-shaped longitudinal magnetic field contact structure, copper-chromium contact material, and has excellent breaking and closing short-circuit current capabilities.

 The product is small in size, light in weight and beautiful in 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 environments.

use
