Product Overview
This series of outdoor high - voltage isolating switches are three - phase AC 50Hz outdoor high - voltage electrical equipment. They are applicable to the three - phase AC 50Hz outdoor power systems of power plants, substations, and large - scale industrial and mining enterprises. They are used for the switching of high - voltage lines under no - load conditions, as well as for electrically isolating and connecting the busbars, circuit breakers and other electrical equipment under inspection from the live high - voltage lines. They have the characteristics of safety, reliability, easy operation, and flexibility. The electrical and mechanical performance of the products meets the requirements of the national standard GB1985 AC High - Voltage Isolating Switches and Earthing Switches. They are widely used as main switches in frame - type reactive power compensation device substations.
