On September 20, State Grid Taizhou Electric Power Company successfully completed a 10kV power generation operation and live-line work on a tension-proof lead wire in the Medical and High-Tech Zone of Taizhou city, Jiangsu Province, through a medium- and low-voltage coordinated operation without power interruption, using a "live-line-led, power generation-supported" maintenance method. This ensured continuous power supply to nine public transformers along the line and facilitated the smooth implementation of the underground wiring project for the North Yangtze River High-Speed Railway.

It has been reported that the North Yangtze River High-Speed Railway, also known as the Shanghai-Nanjing-Hefei High-Speed Railway is a key line of the Yangtze River corridor, one of the main routes in China's "eight vertical and eight horizontal" high-speed railway network. It is also an important part of the coastal and Beijing-Shanghai auxiliary routes. The railway-related road projects in downtown Taizhou, Jiangsu Province, are crucial supporting facilities for leveraging the economic impact of the Shanghai-Nanjing-Hefei high-speed railway along the Yangtze River. They are significant for accelerating the construction of the urban development framework, improving the regional road network structure, and reserving space for the city's future development.

To ensure the relocation and modification project, State Grid Taizhou Electric Power Company promptly sent its key personnel to the site, conducted site surveys, and discussed plans with multiple parties. Taking into account the actual situation, including historical line load data, load forecasting results, and the current road conditions, the company ultimately decided to adopt a "transfer + live-line + power generation" approach to minimize the impact on the power supply during the construction period.

State Grid Taizhou Electric Power Company also took preemptive measures such as converting load-bearing straight poles into tension poles and installing on-pole switches, to prepare for live-line work and power generation operations. On the day of construction, one medium-voltage generator truck and three low-voltage generators were mobilized to the site. Through a coordinated medium- and low-voltage power generation approach, the normal operation of nine transformers was thus ensured.
