The NSRM6-12 fully insulated inflatable ring main switch cabinet has passed the type test of the National High Voltage Electrical Testing Center. This product is widely used in 10kV/6kV distribution systems and is the preferred switch product for various urban and rural users' power transformation and distribution systems.
Modular Design: The switchgear is a modular unit model that can be combined according to different purposes. It is divided into two categories: fixed unit combinations and expandable units to meet the flexible use of compact switchgear in various substations.
The NSRM6-12 fully insulated inflatable ring main switch cabinet is a completely sealed system, with its live parts and switches enclosed in stainless steel bodies. The entire switchgear is not affected by external environmental conditions, ensuring operational reliability and personal safety. It is virtually maintenance-free.
By selecting an expandable bus, any combination can be achieved to achieve complete modularity. Extend the safety insulation and shielding of the busbar to ensure reliability and safety. The solution can also provide a TV based automation solution, forming the concept of intelligent switches and minimizing the workload of on-site installation and commissioning.
Due to the combination of full module and half module, as well as self scalability, it has a very special flexibility. The NSRM6-12 complies with GB standards, and the design lifespan for operation under indoor conditions (20 ºC) exceeds 30 years.
