Product Description
1. Product Introduction
Vacuum interrupter for outdoor load switch is the core component of medium and high voltage power switch. The main function of vacuum interrupter is to cut off the power supply of ceramic shell vacuum interrupter through the excellent insulation of vacuum in the pipe. Moreover, it can quickly extinguish the arc, restrain the current and avoid accidents.
