Vacuum Interrupter for Circuit Breakers Vacuum Contactor Recloser 12kv Silicone Insulation

Product Description

Product Description
A vacuum interrupter, also known as a vacuum switch tube, is a crucial component in high-voltage power switches. Its primary function is to quickly extinguish arcs and interrupt the current after the power supply is cut off, utilizing the excellent insulation properties of the vacuum within the tube. This prevents accidents and ensures safe operation. Vacuum interrupters are widely used in power transmission and distribution control systems and have applications in various industries such as metallurgy, mining, petroleum, chemicals, railways, broadcasting, communications, industrial high-frequency heating, and other power distribution systems.
