Industrial Box Type Fixed Metal Enclosed Switchgear Power Distribution Cabinet

The HXGN17-12 is a compact, metal-enclosed switchgear designed for 12kV three-phase AC 50Hz ring network power distribution systems. As a "Box-Type Fixed" unit, it is engineered for high-reliability performance in urban power grid transformations, industrial parks, and high-rise commercial buildings.

Commonly utilized as a Ring Main Unit (RMU), the HXGN17-12 excels in receiving and distributing electrical energy while providing robust protection against short circuits and overloads. Its primary advantage lies in its air-insulated, simplified structure which offers an exceptionally high performance-to-cost ratio compared to complex gas-insulated units.

• High-Performance Load Break Switch (LBS): Typically equipped with a vacuum load break switch or an SF6 switch, ensuring reliable breaking capacity and a long electrical service life under frequent operation.

• Compact "Space-Saving" Footprint: The box-type fixed design is optimized for environments with limited floor space, such as basement substations, modular containerized power houses, and compact industrial plant rooms.

• Enhanced "Five-Proof" Safety Interlock: Features a mandatory mechanical interlocking system to prevent accidental operation, ensuring the safety of maintenance personnel by preventing entry into live compartments.

• Corrosion-Resistant Fabrication: The enclosure is constructed from high-quality cold-rolled steel or aluminum-zinc plates, treated with an electrostatic powder coating to withstand humid and industrial indoor environments.

• Modular Versatility: The HXGN17-12 can be easily combined into various distribution schemes, acting as an incoming cabinet, outgoing cabinet, or metering unit depending on your grid architecture.

1. Urban Power Grid Construction: Essential for ring network distribution in residential quarters and municipal infrastructure.

2. Industrial & Mining Facilities: Reliable power control for factories requiring a stable 12kV medium-voltage feed.

3. High-Rise Buildings: Perfect for underground power distribution rooms where space is at a premium and safety is paramount.

4. Box-Type Substations: Often used as the high-voltage core component inside pre-fabricated outdoor substations.

• Turnkey Customization: We build each unit according to your Single Line Diagram (SLD), integrating your preferred brands for fuses, LBS, and protective relays.

• Factory-Direct Engineering: By sourcing directly, you benefit from rigorous factory acceptance testing (FAT) and significantly lower procurement costs than traditional middleman distributors.

• Maintenance-Friendly Design: The front-access layout allows for easy inspection of the switch mechanism and cable terminals, reducing downtime during routine servicing.

• Ready for Export: Our equipment is crated in reinforced plywood and includes full English documentation, including wiring schematics and installation manuals.

Q: What is the main difference between HXGN and KYN series?

A: The HXGN is a fixed-type ring main unit, typically using a load break switch (LBS) for ring network applications. The KYN is an armored-removable switchgear using a vacuum circuit breaker (VCB), generally used for more complex protection and higher current requirements.

Q: Can this unit be equipped with a fuse-switch combination?

A: Yes. For transformer protection, we frequently configure the HXGN17-12 with a load break switch and high-voltage current-limiting fuse combination for ultra-fast fault clearing.

Q: Is it suitable for smart grid integration?

A: Absolutely. We can equip the HXGN17-12 with digital sensors and communication modules (RS485/Modbus) for remote monitoring of switch status and fault alarms.
