Subway Electrical System Emergency Repair Project, Shenzhen
Confidential
This emergency repair project was executed at a subway facility in Shenzhen where the public electricity and busbar connectors had been severely burned out due to a short circuit fault. The critical nature of the subway infrastructure demanded emergency repairs to restore power within the shortest possible timeframe. Yanghua flexible busbars proved instrumental in the rapid recovery operation. First, the compact dimensions and high flexibility of the busbar products allowed construction teams to work within the original narrow equipment spaces without needing to expand or modify the existing installation area. Second, and most critically, the flexible busbars did not require advance customization or factory prefabrication. The standardized product could be cut to length and used directly on site, dramatically shortening the overall repair timeline and enabling the owner to restore power far more quickly than would have been possible with conventional bus duct or cable solutions.
Project Background & Challenges
A subway public electrical system suffered catastrophic busbar connector burnout from a short circuit, requiring immediate emergency repair within an extremely short time window. The original installation space was narrow and conventional replacement would involve lengthy customization and fabrication lead times.
- Catastrophic busbar connector burnout from short circuit causing complete power outage at critical subway infrastructure
- Extremely tight repair timeline demanding power restoration within hours rather than days to minimize service disruption
- Original installation space was very narrow, precluding the use of conventional rigid bus duct or multi-cable replacement solutions
- Traditional replacement parts would require factory measurement, customization, and fabrication, adding days or weeks of lead time
Solution
Yanghua flexible busbars were deployed as an emergency replacement, leveraging their compact size for installation in the original confined space and their standardized cut-to-length design to eliminate factory customization delays, enabling same-day power restoration.
- Deployed standardized flexible busbars that could be cut to length and installed immediately on site, eliminating all factory customization and fabrication lead time
- Utilized the compact form factor and high flexibility to fit replacement conductors directly into the original narrow equipment space without modification
- Achieved dramatically shortened repair duration compared to conventional bus duct or cable replacement methods
- Restored power on the same day as installation, enabling rapid resumption of normal subway electrical operations
