This project is a rooftop photovoltaic installation at a factory in Hunan Province, which was accepted and energized on August 27, 2024. The owner selected Yanghua's 1000A high-current flexible busbar solution, primarily deployed between the grid-connected cabinet and the transformer. The flexible busbar's outstanding features include minimal joint requirements, ease of laying, and large, stable current-carrying capacity. The solution saved the owner substantial time, labor, and other comprehensive costs. By integrating photovoltaic and energy storage capabilities, the factory upgraded its energy system while reducing operational expenses. Yanghua's high-current flexible busbar enabled the owner's project to deliver better-than-ever performance and cost efficiency.
Project Background & Challenges
The factory rooftop PV system required a reliable, high-capacity connection between the grid-connected cabinet and the transformer, with the need to minimize joints for reliability while controlling labor and time costs in an active industrial environment.
- The critical connection between the grid-connected cabinet and transformer demanded high current stability with minimal voltage drop
- Traditional solutions with multiple joints introduced reliability risks and required extensive on-site joint fabrication labor
- Factory operations limited the available construction window, requiring a solution that could be installed rapidly
- The roof-to-electrical-room routing path involved elevation changes and limited working space along the cable route
Solution
Yanghua provided a 1000A high-current flexible busbar connecting the grid-connected cabinet directly to the transformer, with minimal joint requirements and easy on-site laying that eliminated the need for complex prefabrication.
- Installed 1000A high-current flexible busbar as a direct, joint-minimized connection between the grid-connected cabinet and transformer
- Leveraged the flexible busbar's easy-laying characteristics to navigate the routing path from rooftop equipment to the electrical room
- Provided large and stable current-carrying capacity with excellent thermal performance under sustained 1000A loading
- Eliminated the time and cost of fabricating multiple intermediate joints, accelerating the overall project timeline
