Disconnector GW9-12KV

Overview of isolating switch:

High pressure isolating switch is important in a power plant and substation electrical system switch electric appliances, with the high voltage circuit breaker, its main function is to: ensure high-voltage electrical appliances and equipment in the safety of repair work, ACTS as the isolation voltage, can't use and cut off,

Input load current and open circuit short circuit current, can be used to produce strong arc not only some of the switching operation.

The structure of the isolating switch:

Commonly used high pressure isolating switch mainly includes the following parts: the conductive parts, insulating parts, transmission parts, base.

The purpose of isolating switch:

High voltage isolation switch points outdoor and indoor, outdoor type including single switch and three pole isolator, commonly used for the open circuit isolating switch power supply circuit is separated from the user; Indoor type with high voltage circuit breaker in series connection, form a complete set to use, to ensure the reliability of the power outage. In addition, in the high pressure of complete sets of power distribution device, isolating switch commonly used as a voltage transformer, lightning arrester, the high pressure control of distribution transformer and measuring tank used electrical appliances.

Production technology of high pressure isolating switch:

GW9 type series isolating switch, is divided into: according to the current **0 a, **0 a, **0 a three,

Otherwise huacheng type, ordinary type for customers to choose. Plate galvanized, connecting bolts, etc. Standard parts are stainless steel
