Switchgear Solutions for Solar PV Plants & Wind Farms
Zhejiang Gangheng Electric has engineered power distribution equipment since 2004. As a National High-Tech Enterprise and qualified supplier to the State Grid Corporation of China, we manufacture Medium Voltage (MV) and Low Voltage (LV) switchgear purpose-built for the electrical demands of utility-scale renewable energy projects - from desert solar farms in the Middle East to grid-connection substations across Africa.
HV/MV/LV Switchgear Products for Renewable Energy Generation
Switchgear is the backbone of any solar or wind farm's electrical system - controlling, protecting, and distributing power from generation to the grid.
Gangheng offers fully customizable models configured to your project's grid-connection voltage and local standards.
High & Medium Voltage Switchgear - 12kV & 40.5kV
KYN28-12 Indoor Metal-Clad Moveable Switchgear (12kV)
Widely used at step-up transformer feeders and collection circuits in solar PV plants. Supports vacuum circuit breakers and microprocessor-based protection relays for automatic fault isolation.
KYN61-40.5 Armored Removable Switchgear (40.5kV)
Designed for main incoming panels at large-scale wind farm substations requiring higher voltage ratings and arc-flash protection.
Installed on the LV side of solar inverters and wind turbine generators, our LV switchgear manages initial power distribution before voltage step-up. Custom bus configurations and protection relay coordination available.

Built for Harsh Field Conditions in Solar & Wind Environments
Renewable energy sites present some of the most demanding environmental conditions for electrical equipment. Gangheng switchgear is specifically configured for:
Desert & Arid Climates
IP54+ enclosure ratings, anti-sand filter systems, and internal thermostat-controlled heating/cooling units to handle extreme temperature swings common in Middle Eastern solar projects.
Coastal & High-Humidity Sites
Hot-dip galvanized enclosures and epoxy anti-corrosion coatings rated for salt-spray environments up to C4/C5 category.
Remote Off-Grid Locations
SCADA-compatible protection relays with RS485/IEC 61850 communication support for remote monitoring without on-site personnel.

Frequently Asked Questions
Q: What voltage levels does Gangheng cover for solar farm collection systems?
A: We cover the full voltage stack: 0.4kV LV for inverter output, 12kV MV for feeder collection, and 40.5kV MV for main step-up substation incoming panels. Custom configurations for 33kV or 66kV systems are available on request.
Q: Can your switchgear meet the requirements of Middle Eastern or African utility grid codes?
A: Yes. We work directly with your project's electrical engineer or the local grid operator's specification to ensure relay settings, busbar ratings, and labeling comply with national grid connection standards. We have supplied to projects in Iran, Tanzania, Zimbabwe, and Kyrgyzstan.
Q: How do you handle factory acceptance testing (FAT) for international renewable projects?
A: All units undergo routine testing per IEC 62271 at our factory prior to shipment. We can arrange third-party witnessed FAT for projects requiring SGS, BV, or TÜV inspection. Full type test reports for KYN28-12 and KYN61-40.5 are available on request.
Q: What warranty terms apply to switchgear used in solar or wind installations?
A: We offer 12 months warranty from project acceptance, plus a 5-year latent defect protection period. 24/7 remote technical support and spare parts supply at non-premium pricing are included as standard commitments.
