Product overview:
SRM6-12 Gas Filled SF6 metal-enclosed fully insulated series ring main unit is widely used in 10kV/6kV power distribution systems, and is the preferred switch product for all types of substation and distribution systems for urban and rural users.The switchgear is a modular unit mode, which can be combined according to different purposes; there are two types of fixed unit combination and expandable unit to meet the exible use of compact switchgear in various substations.
SRM6-12 gas flled 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 filled 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:
◇SRM6-12 series gas flled 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, switch and point parts are completely enclosed in a stainless steel shell. The cavity is flled 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 ooding, 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.
