Consult NowProduct introduction
HXGN15-12 unit modular sulfur hexafluoride ring netcabinet is a new generation with sulfur hexafluoride switch as the main switch. The whole cabinet is air insulated. It is suitable for distribution automatic, and it is both compacted and extensible metal-enclosed switchgear equipment.
Its features are as follows: simple structure, flexible operation, reliable interlocking, and convenient installation. It can provide satisfactory technical solutions to meet different requirements of users according to different occasions. It adopts sensor technology and uses the latest protection relays. It is coupled with advanced technical performance and light and flexible assembly solutions.
Main application and scope of application
The ring network cabinet is a three-phase ac indoor distribution device with rated voltage of 12kV. It is widely used in industrial parks, residential areas, commercial centers, cable network opening and closing and industrial and mining enterprises. The power supply system is used for receiving and distributing electricity, which can greatly improve the reliability of power supply.
