Due to the good effect of DC based de-icing technique used in overhead transmission line, it has been widely used in conductor de-icing of 500kV and above AC transmission line line. The ground wire de-icing technology becomes the current problem to be solved. In Shi Bing–Xian Ling Shan 500kV transmission line anti-icing renovation project, according to the complex ground wires, we made deeply study on the DC based de-icing technique for the project and calculated and analyzed. Then we proposed appropriate solutions for de-icing of this project and achieved good effect. This paper based on engineering practice combined with DC based de-icing technology and proposed next prospect.
