SRM 16-12 inflatable SF6 metal-enclosed fully insulated ring network switch cabinet is widely used in 10kV/6K power distribution system. It is the preferred switch product for all kinds of power distribution systems in urban and rural areas. 

The switch cabinet is a modular unit model, which can be combined according to different USES. The combination of fixed units and expandable units meet the needs of flexible use of compact switchgear in various substations. 

The SRM 16-12 inflatable switchgear is a fully sealed system with all live parts and switches enclosed in a stainless steel housing. The entire switch device is not affected by external environmental conditions, so as to ensure the reliability of operation and personal safety, and to achieve maintenance-free. By selecting an extensible bus, any combination can be achieved to achieve full modularity. Extended bus safety insulation and shielding ensure high reliability and safety. SRM 16-12 inflatable switchgear can also provide Iv-style automation solution, forming the concept of intelligent switch, and reduce the field installation and debugging workload to a minimum. 

The SRM 16-12 inflatable switchgear cabinet is divided into non-extended standard configuration and expandable standard configuration. Because of the combination of full module and half module and its own extensibility, it has very special flexibility. 

The SRM 16-12 inflatable switch performs GB standard. The design life of operation under indoor conditions (40℃) and outdoor conditions (-50℃) exceeds 30 years.
