Will high-voltage lines leak electricity in foggy weather?

Yes. In foggy weather, if high-voltage lines or cables are damaged or poorly grounded, leakage will occur. Therefore, in foggy weather, the quality of the insulation and joints of high-voltage lines is very critical and requires strict inspection and maintenance. In addition, when leakage is discovered, timely measures must be taken to deal with it to avoid harm to personnel and equipment. High-voltage lines usually refer to transmission lines that transmit voltages above 10kV (inclusive). According to GB/T2900.50-2008, definition 2.1 stipulates that high voltage usually does not include 1000V. The voltage levels of China's domestic high-voltage transmission lines are usually divided into: 35kV, 110kV, 220kV, 330kV, 500kV, 750kV, etc.
