Outdoor High Voltage Disconnecting Switch

Outdoor High Voltage Disconnecting Switch is suitable for AC power grid system with rated voltage 3.6 kV and above and operating frequency 50 Hz and below. It is a switching appliance with simple structure. In general, it may only be used to switch on and off when the power grid is disconnected, or switch on and off the small current circuit that meets the requirements.

The product can be divided into general type and stain resistant type in terms of using environment. It should be installed in a place with ambient temperature from -40¡ãC to +40¡ãC, and altitude not more than 1,000 m.

Execution standard of product: GB/T1985-2014 High Voltage AC Disconnectors and Earthing Switches.
