Real Project Case

Project Name

Vietnam 80MW Industrial Solar Power Plant Grounding Connection Project

Project Background

The 80MW industrial solar power plant in Vietnam is located in a tropical climate area with high humidity, frequent rainfall, and long-term outdoor exposure. The project included more than 120 inverter units, multiple transformer stations, and a large-scale grounding network. According to IEC 60364 electrical installation requirements, the grounding system needed to maintain stable electrical connection performance and ensure reliable fault current discharge.

Due to the large number of electrical connection points and complex cable layouts, the EPC contractor required a grounding connection solution with high conductivity, accurate installation dimensions, and long-term corrosion resistance. After technical evaluation, the project selected Saint Ni Lightning Protection customized copper busbars for the grounding system connection.

Project Solution

Saint Ni Lightning Protection supplied customized copper busbars with a thickness of 8mm, width of 80mm, and customized drilling positions according to the electrical layout drawings. The busbars were connected with grounding conductors, inverter cabinets, and transformer grounding points to create a stable and low-resistance electrical connection network.

All copper busbars were manufactured from high-purity copper and processed through CNC cutting, drilling, and surface treatment. The connection points were accurately matched with equipment terminals, reducing installation errors and improving construction efficiency. The complete grounding system was tested using a four-wire resistance measurement method after installation, with the grounding resistance maintained below 1Ω.

Application Results

After commissioning, the grounding connection system operated stably under continuous outdoor conditions. The copper busbars maintained excellent electrical conductivity without obvious oxidation or connection loosening after 24 months of operation. Compared with traditional cable connection methods, the project reduced installation time by approximately 30% and improved the overall neatness and maintainability of the grounding layout.

The Saint Ni Lightning Protection copper busbar solution successfully met the project's electrical safety requirements and provided a reliable grounding connection structure for large-scale renewable energy facilities.
