HXGN-12 Fixed Metal Closed Switch Equipment

Fixed Metal Closed Switchgear (ring net cabinet)

Introduction - Fixed Metal Closed Switchgear [High Voltage switchgear]
HXGN-12 Fixed Metal Closed Switchgear (ring net cabinet) is an indoor box-type AC metal closed Switchgear which has10KV three-phase AC rated voltage and 50Hz rated frequency. It is applied to the power distribution system, ring network power supply or double power radiation supply of factories, workshops residential districts and high-rise buildings, etc. It receives, distributes and protects the circuit. It also suits for the box substation.

Model Meaning of Fixed Metal Closed Switchgear Product Standards - High Voltage switchgear
1. GB3906 “3－35kv AC Metal Closed Switchgear ”
2. GB3804-90 “3－63kv AC High-voltage Load Switch”
3. IEC-298 “AC Metal Closed Switchgear and Control Equipment”
4. IEC-420 “High-voltage AC Load Switch—Fuse Combination Electric Appliance”
Structure of Fixed Metal Closed Switchgear [High Voltage switchgear]
1. HXGN-12 ring net cabinet is assembled and welded by mold materials. The overall structure is solid. On the top of the cabinet there is busbar room. The meter room is in front of it. The central upper part is where the load switch installed. Below the cabinet are cable wires and other parts (e.g.: CT, PT). Each room is reliably separated.
2. The main switch has adopted advanced Italian technology which has static contact insulation cover FN12A-10D/630 air-compressed load switch and FN12-10RD/100 load switch - Fuse Combination Electric Appliance or C3 pole load switch produced by ABB Company, domestic high quality load switch. High rated open and interrupt current frequency and reliable arc extinguishing performance.
3. Perfect misuse prevention equipment.
4. Small volume; safe and reliable.
