Product Description

General

 

Outdoor high voltage AC isolation switch (hereinafter referred to as "isolation switch"), suitable for installation on outdoor high voltage distribution equipment lines, for 10 kV lines in the case of voltage and no load, as well as the maintenance of high voltage bus, circuit breakers and other electrical equipment and live high voltage lines for electrical isolation. It can also be used to split small capacitive and inductive currents.

Service environment

 

• The altitude does not exceed 1000M;

• The upper limit of the ambient temperature is 40ºC, the lower limit is -25ºC;

• No conductive or chemically acting gas and steam place;

• No fire, explosion danger, seriously polluted places;

• Not subject to serious vibration or impact (such as in the pickaxe, dredger) place

Key Feature

 

• The isolation switch consists of three single-pole switches.

• Each single-pole isolation switch has the same components, including base, strut and operating insulator, front and rear static contacts, knife and arc Angle

• CS operating mechanism is used for those with grounding knife, CS8-5 operating mechanism is used for those without grounding
