Description
The XGN15-12 metal-enclosed ring network switchgear uses the SF6 load switch as the main switch and the whole cabinet adopts air insulation. This product is compact in structure, easy to install, and flexible to operate. It is equipped with multiple interlocks. Coupled with motor drive unit, PT, CT, UPS, and FTU, it can be used in the automation system of the distribution network. With modern sensor technology, latest protection relay, flexible assembly solution, our ring network switchgear can fully meet the constantly changing market demands.
Our product is equipped with the FLN36~12D load switch, which is produced independently by our company, or the SFG load switch produced by ABB Company. We can also configure the most advanced imported ISM series vacuum circuit breaker with magnetic actuator or domestic VB series vacuum circuit breaker according to the needs of users.
There are two operation modes: manual operation and electric operation.
