Product Description

12/24kv high voltage SF6 gas insulated switchgear gis ring main unit switchgear

 

 

Main Application
The SF6 gas insulated switchgear (GIS) is used for receiving and distributing electric energy in power system. It is widely used in processing industry, civil  and power supply terminal,such as:

· Small secondary distribution station
· Switching station
· Urban residential area
· Airport
· Railway, tunnel


Product Features

· The switchgear is equipped with perfect "Five Prevention" interlock device, which can completely eliminate personnel injury and equipment operation failure caused by human error operation.

· The gas insulated switchgear uses SF6 gas as arc extinguishing and insulating medium

· The switchgear is fully sealed and insulated, and the protection level reaches IP67.

· The switchgear has reliable safe pressure relief channel, which can guarantee the safety of personnel even in extreme cases

· The whole switchgear is not affected by the external environment.

· Cabinet size is small, does not occupy space, and easy to install

· The switchgear can be equipped with electric, remote control and detection devices according to different needs of users
