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
