Introduction:
1. This type of vacuum switch tube adopts one-time sealing and draining process, ceramic shell, and the contact is made of CuWC material. It has the characteristics of high insulation level, low interception value, strong arc extinguishing ability, long life, small size, simple maintenance, and no explosion hazard. , No pollution, low noise and other advantages.
2. The contactor assembled with it is used for the control and protection of the power transmission and distribution system of the electric power, machinery, chemical industry, metallurgy, mining and railway departments, especially suitable for places with frequent operations.
