NSRM-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.
