High Quality Best Hv System Manufacturer – Solid-sealed pole for Vacuum interrupter – Shone

Brief description of the product:

Solid-sealed Pole For Vacuum Interrupter is an integral part of the circuit breaker Pole by embedding the conductive parts of the Vacuum Interrupter and the circuit breaker into a Solid insulating material such as epoxy resin or thermoplastic material that is easy to cure.

Solid-sealed Pole For Vacuum Interrupter has the following advantages:

One is modular design, simple structure, less removable parts, high reliability;

The second is the extremely high insulation bar capacity. It will surface insulation into volume insulation, compared with air insulation, reduce the impact of the environment, greatly improve the insulation strength.
It can make the size of the circuit breaker smaller, which is beneficial to the miniaturization of the switch cabinet.

In the past, the insulating shell of the vacuum arc extinguishing chamber was exposed to the air and polluted by dust and humidity. In order to reduce this effect, it is required that the shell of the vacuum arc extinguishing chamber has enough length, which not only affects the miniaturization of the vacuum arc extinguishing chamber, but also affects the performance and reliability of the vacuum arc extinguishing chamber. The solid seal pole has the following advantages: compared with the traditional assembly pole, the number of parts of the solid seal pole is greatly reduced, the lap surface of the conductor is reduced from 6 groups to 3 groups, the connecting bolt is reduced from 8 to 1~3, the simple structure greatly improves the reliability of the circuit breaker; Because the vacuum arc chamber is embedded in the solid material, no further treatment is required and the solid seal pole achieves high insulation strength; After the vacuum arc extinguishing chamber is embedded in solid material, the influence of the external environment of the pole on the vacuum arc extinguishing chamber is minimized.
