On February 25th, the State Grid Sichuan Electric Power Company successfully used cable insulation on-site repair technology for the first time at the Zhangzhou 220 kv Lizhuang substation to implement field insulation repair of the 10 kV operating cable, indicating that China's grid cable insulation repair technology has achieved significant The breakthrough will provide technical support for solving the aging problem of urban distribution cable insulation in the future.
The cable repair technology uses the method of pressure injecting the silicone repair fluid to the core of the high voltage cable to make the repair solution chemically react with water, and the generated silicone material fills the gap of the cable tree, thereby eliminating water trees, The use of this technology is the first time in China to repair cable insulation and extend the life of the cable.
