GIS 24kv 50HZ SF6 Ring Main Unit

SF6 high-pressure gas-filled ring main unit uses SF6 gas as the arc extinguishing and insulating media. The switchgear is a fully sealed and fully insulated structure: the bus bars and switches are all enclosed in stainless steel shells. The cavity is filled with 1.4 bar of SF6 gas, and the protection level reaches IP67: the entire switch device is completely immune to external environmental conditions, and can ensure the normal operation of the switch even under extreme conditions such as short-term flooding. The product is maintenance-free for life. The switchgear has a reliable and safe pressure relief channel, which can guarantee the personal safety of the operator even under extreme conditions. The switchgear is divided into two types: fixed unit combination and expandable unit combination. The switch cabinet usually enters and exits from the front, and can also realize side exit or side expansion according to different installation positions. The switchgear size is easy to install, and can be suitable for places with small space and poor environmental conditions. The switchgear can be equipped with electric, remote control and monitoring devices to simulate the different needs of users.
