Power Distribution Equipment for Industrial and Infrastructure Projects
Yihong supplies custom-engineered medium- and high-voltage switchgear, low-voltage switchgear, compact substations, cable branch boxes, and power transformers. All equipment is designed and manufactured in strict compliance with international standards, including IEC 62271, IEC 60076, and IEEE.
Deployed globally across utility substations, power plants, automated factories, and renewable energy farms, our equipment is built to withstand diverse operating environments-from high-altitude and coastal zones to extreme temperature variations. We initiate every project directly from your site-specific electrical parameters and application conditions, ensuring a precise engineering fit rather than relying on rigid, off-the-shelf limitations.
Substation Projects: Primary and secondary distribution equipment, including IEC-compliant medium-voltage switchgear and custom-capacity transformers, featuring coordinated protection schemes and specific IP enclosure ratings.
Industrial Power Projects: Heavy-duty MV/LV switchgear, power distribution centers (PDCs), and motor control centers (MCCs) designed for continuous industrial loads and severe manufacturing environments.
Solar Power Projects
Prefabricated substations, PV grid-connected inverter cabinets, and step-up transformers with outdoor-rated enclosures engineered for high ambient temperatures and rapid cycling.
Wind Power Projects
Compact wind-turbine tower substations and specialized transformers built to withstand vibration, moisture, and highly variable electrical loads.
Commercial & Residential Grids
Space-saving compact substations and low-voltage distribution boards optimized for urban environments with strict safety and noise regulations.
Core Product Configurations
Our engineering team adapts rated voltage, short-circuit current ratings, transformer capacity, and enclosure dimensions to your exact specifications.
Medium & High Voltage Switchgear
Standard models including XGN15-12-630, XGN17-12-630, and KYN28-12-630 for primary distribution, fully customizable to project parameters.
Low Voltage Switchgear
Robust distribution panels, LV switchgear assemblies, and intelligent MCCs for automated production and power plants.
Compact Substations
Factory-integrated units including secondary compact substations, package substations, and specialized PV prefabricated cabins.
Power Transformers
High-performance distribution units, including high-voltage, underground, solid-state, step-down, and single-phase pad-mounted transformers.
Cable Branch Boxes
Indoor and outdoor medium/high-voltage cable tap-off enclosures configured for specific insulation types and environmental exposure.
Quality Assurance & Global Standards
Operating from a 10,000 square meter manufacturing facility with a dedicated 5,000 square meter production and wiring floor, Yihong is certified under strict ISO 9001 quality management systems.
100% Factory Acceptance Testing (FAT)
Every assembly undergoes rigorous electrical, functional, and dielectric verification before packing.
Advanced In-House Diagnostics
Equipped with high-voltage testing systems and partial discharge testing equipment to guarantee operational reliability.
Third-Party Inspection
We fully accommodate independent verification by globally recognized agencies such as SGS, Bureau Veritas (BV), or TÜV upon request.
Comprehensive Project Documentation
To facilitate smooth local grid authority approvals, customs clearance, and site commissioning, we provide a complete, export-ready documentation package:
Certified Product Datasheets & Technical Specifications
Detailed Primary and Secondary Electrical Schematics
Product Configuration & Bill of Materials (BOM)
Factory Acceptance Test (FAT) Records
Quality Compliance & Material Certificates
Comprehensive Operation and Maintenance (O&M) Manuals
