The HXGW-12 box-type fixed metal-enclosed switchgear (ring main unit) is designed for AC 50Hz, 10KV networks, serving as a solution for breaking load, short-circuit protection, and closing short-circuit current. It is equipped with manual and electric spring mechanisms for operating load switches, with grounding and isolation switches utilizing manual operation mechanisms.

• Operational altitude: Up to 10,000m.
• Daily average humidity ≤ 95%, monthly average ≤ 90%.
• Environment free from corrosive/flammable gases or severe vibrations.

1. Specify model, specification, quantity, color, and delivery period at the time of order.
2. Provide wiring schemes, component models, and specific requirements.
3. Detail high voltage incoming/outgoing cable cross-sections, lightning arrester installations, and transformer capacity (KVA).
4. Clarify transformer room type (terminal or ring network), low voltage circuits, and metering requirements.
5. Select preference for domestic or imported primary components (load switches, fuses, terminals).
