High-Reliability Switchgear Products For Industrial Process Continuity
Continuous manufacturing demands electrical infrastructure that can withstand high short-circuit faults, frequent motor-starting inrush currents, and corrosive or dust-laden atmospheres. Gangheng provides a comprehensive range of MV/LV equipment engineered to international IEC standards, fully customizable with top-tier components and adaptable to the most restrictive factory floor layouts.

High & Medium Voltage Switchgear - 12kV & 40.5kV
KYN28A-12 Indoor Metal-Clad Moveable Switchgear (12kV)
The industry-standard choice for main factory substations, heavy machinery incoming bays, and large-scale plant distribution. Constructed with imported aluminum-zinc plates processed via high-precision CNC machinery, it supports vacuum circuit breakers (ZN63A-12/VD4) and advanced protection relays. Designed with a robust 5-prevention mechanical interlock system, it delivers foolproof personnel safety and high structural strength for demanding industrial grids.
KYN61-40.5 Armored Removable Switchgear (40.5kV)
Engineered for 35kV primary industrial receiving substations, steel mills, and heavy chemical complexes requiring massive short-circuit withstand capabilities (up to 31.5/40kA). It supports domestic ZN85-40.5 vacuum circuit breakers or premium Schneider SF6/Alstom FP series circuit breakers, offering exceptional insulation performance and internal arc fault protection.
HXGN17-12 Box-Type Fixed Ring Main Unit (12kV)
A highly compact, indoor metal-enclosed ring main unit utilizing vacuum/SF6 load break switches (FN12-12D/FN25-12D). Ideal for factory workshop branch networks and localized transformer loop connections where space constraints are severe and maintenance access is limited.



Intelligent Low Voltage Switchgear & MCC - 0.4kV / 380V
MNS & GCS Series Low Voltage Withdrawable Switchgear
Specifically optimized as Intelligent Motor Control Centers (MCC) for continuous chemical and manufacturing plants. These systems feature fully withdrawable functional drawer modules that support live, hot-swapping under power. If a drawer circuit faults, it can be replaced in minutes without isolating the main busbar, keeping the rest of the factory production line running seamlessly. Custom bus configurations and advanced protection coordination prevent catastrophic cascade tripping.

Heavy Industrial Application Scenarios
Industrial projects involve harsh operating environments that dictate strict technical compliance. Gangheng equipment is field-proven across the following specialized applications.
Chemical & Petrochemical Refining
Continuous processes cannot tolerate power dips. Our solutions deploy XGN66 or KYN28 high-voltage cabinets matched with GGD/MNS low-voltage systems and fire-safe dry-type transformers. We specialize in upgrading power systems inside space-constrained chemical switchrooms, emphasizing strict mechanical interlocking for chemical plant safety.
Mining, Minerals & Cement Processing
Extreme dust, moisture, and massive motor-starting loads define this sector. Gangheng customizes enclosures up to IP54/IP55 protection ratings, utilizing reinforced anti-corrosion finishes and heavy-duty dust filters to protect critical internal components from conductive airborne particulates.
Continuous Manufacturing & Motor Control Center (MCC)
Automotive assembly, pulp and paper, and automated packaging lines rely on huge motor arrays. We configure MNS/GCS drawout cabinets with dedicated ACB/MCB protection, harmonic suppression, and smart metering to manage heavy inductive loads while ensuring zero downtime during routine maintenance.
Factory Expansion & Substation Capacity Upgrades
Rapid industrial scaling requires agile power engineering. We specialize in rapid-delivery transformer and switchgear capacity upgrades, minimizing on-site downtime through prefabricated substations and pre-tested, plug-and-play internal switchroom layouts.
Proven Delivery on Heavy Industrial Projects
The client operated a continuous chemical production line driven by multiple high-power motor loads. Following a major capacity expansion, their existing power distribution system was severely overloaded. The facility needed an entire high-to-low voltage upgrade executed within the strict spatial footprints of an existing in-building switchroom.
Our Solution: The Gangheng engineering team conducted an immediate on-site site assessment, reviewing single-line diagrams (SLD) and load characteristics. We delivered an integrated package consisting of XGN66-12 fixed AC metal-enclosed high-voltage switchgear (selected for its tight footprint and robust 5-prevention safety interlocks), a 1000 kVA fire-safe dry-type transformer for indoor safety, and a series of GGD fixed low-voltage cabinets to handle heavy motor-starting duty cycles.
Result: The entire layout complied perfectly with clearance and ventilation standards, allowing a flawless integration that minimized factory shutdown during installation. The client confirmed long-term supply cooperation.

Frequently Asked Questions (Industrial Edition)
Q: Our industrial facility runs a 24/7 continuous line. Can we perform maintenance on your LV switchgear without shutting down the factory?
A: Yes. Our GCS and MNS low-voltage switchgear series are built with modular, fully withdrawable drawer compartments. These modules support live hot-swapping. In the event of a specific motor circuit loop fault or routine maintenance check, you can safely pull out the individual drawer module, service or replace it, and plug it back in within minutes. The remaining functional modules and main busbars stay fully energized, ensuring absolute zero downtime for your main manufacturing processes.
Q: Our existing plant switchroom has a non-standard shape and very limited clearance. Can you customize the physical sizes of KYN28 or MNS cabinets?
A: Absolutely. Industrial retrofits and capacity expansions often happen within tight, pre-existing civil spaces. Our engineering team specializes in non-standard physical modifications. We can adjust the cabinet array, structural dimensions (depth/width), cable entry positions (top or bottom entry), and busbar alignments based directly on your architectural layouts and single-line diagrams.
Q: How do your switchgear cabinets mitigate the harsh environments of chemical plants (corrosion) or mining (dust)?
A: For chemical plants, we offer specialized anti-corrosion surface treatments, including the use of premium SS304 or SS316 stainless steel enclosures and specialized polyurethane sealing gaskets. For mining and cement sectors, we upgrade the enclosure sealing up to IP54/IP55 and add specialized louvered ventilation panels lined with heavy-duty, cleanable dust filters to ensure internal electronics remain free from conductive or abrasive particles.
Q: Do you provide full type test reports and schematic support for EPC project bidding?
A: Yes. We provide full technical packages to support EPC contractors and plant engineers during the design and bidding phases. This includes full IEC type test reports, single-line diagrams (SLD), internal schematic layout blueprints, protection relay coordination calculations, and factory acceptance testing (FAT) logs.
