HXGN-12 indoor metal-enclosed ring network switchgear

Product Description

　　Indoor AC metal-enclosed ring main unit switchgear is suitable for indoor three-phase 50/60Hz, rated voltage 7.2～12kV power systems. It is used to receive and distribute three-phase AC power and to automatically control the switching of operating circuits, protect against faults (including overload, short circuit, overvoltage, etc.), monitor, and record events. This product is characterized by its small size, light weight, simple operation, safe use, and easy maintenance; it is widely used in urban power grid construction and renovation projects, industrial and mining enterprises, high-rise buildings, and public facilities, as a ring main power supply unit and terminal equipment, and can also be installed in prefabricated substations.

　　The design and manufacture of HXGN-12 ring main units fully comply with GB/T 3096 "3.6kV-40.5kV AC metal-enclosed switchgear and control equipment", GB/T 3804 "3.6kV-40.5kV high-voltage AC load switches", GB/T 1985 "High-voltage AC isolating switches and earthing switches", GB16926 "High-voltage AC load switch-fuse combination electrical appliance", GB/T1984 "High-voltage AC circuit breaker", DL/T 404 "3.6kV-40.5kV AC metal-enclosed switchgear and control equipment".
