The Guanwei Line is a critical power artery for the Hongze Economic Development Zone, supporting the electricity needs of multiple manufacturing enterprises. To counter the challenges of soaring demand under extreme heat, the company made early preparations and strict deployments, reinforcing straight-line poles stressed under high temperature and heavy loads. By using live-line techniques, they minimized disruptions to residential power consumption.
