Metal Closed High Voltage Switchgear Corrosion Resistant AIS Air Insulated Switchgear

The HXGN15-12 is a new generation of air-insulated, metal-enclosed switchgear designed for 12kV three-phase AC 50/60Hz power systems. Serving as a core component in Ring Main Units (RMU), it utilizes the SF6 Load Break Switch (LBS) as the primary switching element.

Engineered for reliability and compact efficiency, this switch cabinet is the ideal solution for urban grid renovation, industrial power distribution, and commercial high-rise infrastructure. Its modular design allows for arbitrary combinations, facilitating flexible system expansion and distribution automation.

• Advanced SF6 Interruption Technology: Utilizes sulfur hexafluoride (SF6) gas for superior arc extinguishing and insulation, ensuring high breaking capacity and maintenance-free operation for the switch chamber.
• Modular & Extensible Design: Each unit is an independent module. Cabinets can be combined or expanded according to project requirements (Incoming, Outgoing, Metering, or PT units).
• Superior Safety "Five-Proof" Interlock: Features a robust mechanical interlocking system that prevents misoperation, ensures the grounding switch is correctly positioned, and protects personnel from accidental entry into live compartments.
• Compact & Space-Saving Footprint: Its narrow-width design is specifically optimized for tight urban substations, box-type transformer stations, and underground electrical rooms.
• Corrosion-Resistant Enclosure: Constructed from 2mm aluminum-zinc plated steel plates with multi-bending processes, offering exceptional structural strength and resistance to harsh environmental conditions.

1. Urban Residential Grids: Reliable ring network power supply for densely populated residential areas.
2. Industrial & Mining Enterprises: High-voltage control and protection for heavy industrial production lines.
3. Infrastructure Hubs: Essential for airports, subways, railways, and hospital power distribution.
4. Commercial Real Estate: Centralized power management for high-rise office towers, shopping malls, and hotels.
5. New Energy Integration: Compact solution for wind farm collection points and solar PV substations.

• Global Brand Integration: Can be equipped with high-end vacuum circuit breakers from ABB (VD4) or Schneider, or cost-effective domestic alternatives based on your budget.
• Smart Grid Ready: Compatible with modern distribution automation systems (DTU/FTU) and remote monitoring sensors for real-time status tracking.
• Rigorous Testing: Every unit undergoes factory acceptance testing (FAT) for partial discharge, insulation resistance, and mechanical operation before shipment.
• Expert Support: We provide full CAD single-line diagrams (SLD) and technical consultation to ensure the equipment meets your local utility requirements.

Q: Is the HXGN15-12 suitable for outdoor use?

A: It is an indoor rated cabinet (IP3X). For outdoor applications, it must be installed within a secondary protective enclosure, such as a Box-Type Transformer Substation.

Q: Does it support remote control?

A: Yes. We can configure the switchgear with motorized operating mechanisms and communication modules for SCADA integration and remote switching.

Q: What is the lead time for customized configurations?

A: Depending on the complexity of the internal scheme and component availability (e.g., specific breaker brands), the typical production time is 2–4 weeks.
