KYRM6-12 gas plled ring main unit is a completely sealed system,and its live parts and switches are enclosed in a stainless steel body. The entire switchgear is not affected by external environmental conditions, thereby ensuring operational reliability and personal safety, so as to achieve maintenance-free. By choosing an expandable bus,any combination can be made to achieve full modularity. The safety insulation and shielding of the extended bus bar ensure reliability and safety. SRM6-12 gas Plled ring main unit can also provide TV-based automation solutions,forming the concept of intelligent switches,and minimizing the workload of on-site installation and commissioning.


Product main feature

KYRM6-12 series gas filled ring main unit features SF6 gas used as arc extinguishing and insulating medium. The Unit is a fully sealed and fully insulated structure; the bus bar, switchand point parts are completely enclosed in a stainless steel shell. The cavity is filled with 1.4bar SF6 gas, and the protection level reaches IP67; the entire switch device is completely unaffected by external environmental conditions, and the normal operation of the switch can be guaranteed even under extreme conditions such as short-term Booding, and the product is maintenance-free for life.

● The Unit has a reliable and safe pressure relief channel, which can guarantee the personal safety of the operator even in extreme situations.

● The Unit is available of two types: fixed unit combination and expandable unit combination.

● The Unit usually enters and exits from the front, and can also achieve side exit or side expansion according to different installation positions.

● The size of the Unit is easy to install, and it can be suitable for places with small space and poor environmental conditions.

● The Unit can be equipped with electric motoring, remote control and monitoring devices to meet the different needs of users.
