China Outdoor High Voltage Three Phase Disconnector Switch

Disconnector Switch

China Outdoor High Voltage Three Phase Disconnector Switch

    An electrical device for the reliable disconnection of certain sections of a high-voltage electrical network when there is no current in them. The use of isolating switches (either alone or in combination with high-speed short-circuiting devices) makes it possible to simplify the arrangement of switching points and transformer substations and to eliminate expensive high-voltage circuit breakers.
