Arc Shield Nm8-250 Arc Extinguishing Chamber Red Steel Paper Arc Chute Extinguishing

The arc extinguishing chamber is the core component of medium and high voltage power switch. Its main function is to make the medium and high voltage circuit quickly extinguish the arc and suppress the current after cutting off the power supply through the excellent insulation of vacuum in the pipe, which is mainly used in the power transmission and distribution control system, and also used in metallurgy, mining, petroleum, chemical industry, railway, broadcasting, communication, industrial high-frequency heating Thermal distribution system. It has the characteristics of energy saving, material saving, fireproof, explosion-proof, small volume, long service life, low maintenance cost, reliable operation and no pollution. The vacuum interrupter can be divided into the interrupter for circuit breaker and the interrupter for load switch. The interrupter for circuit breaker is mainly used for substation and power grid facilities in the power sector, and the arc extinguishing chamber for load switch is mainly used for the end users of power grid.
