The switchgear adopts a modular unit mode, which can be combined according to different purposes: it is divided into two categories: fixed unit combination and expandable unit, meeting the flexible use needs of various substations for compact switchgear.


The JEXGN □ -12 inflatable switchgear is a completely sealed system, with all live parts and switches enclosed in a stainless steel casing. The entire switch device is not affected by external environmental conditions, ensuring operational reliability and personal safety, and achieving maintenance free operation. By selecting expandable busbars, any combination can achieve full modularity. The expansion of busbar safety insulation and shielding ensures high reliability and safety. The JEXGN □ -12 inflatable switchgear can also provide a TV based automation solution: forming the concept of intelligent switches and minimizing on-site installation and debugging workload.


JEXGN □ -12 inflatable switchgear is divided into non expandable standard configuration and expandable standard configuration. Due to its combination of full modules and half modules, as well as its own scalability, it has extremely special flexibility.


JEXGN □ -12 inflatable switch complies with GB standards.

The design lifespan for operation under indoor conditions (20 ℃) exceeds 30 years.
