In the power transmission line deicing antifreeze system, a split power transmission sub line is separated into one or a plurality of segments, and at juncture or end point of adjacent lead segments, in-phase split leads are connected as split lead pairs. In lead segment center position, each lead pair is connected with an independent current circuit, the current goes through front and back lead to heat the lead for deicing. The power transmission line deicing antifreeze system also comprises an insulator which is designed as hollow structure with upper and lower air intake and exhaust openings. Hot gas generated by an electrical hot air generator installed on a power transmission line pole enters the insulator via the air intake opening and flows out from the air exhaust opening to heat the insulator for deicing and antifreeze. Deicing antifreeze work scope of the insulator and a lead deicing scope share a same line segment, and deicing antifreeze power supply and lead deicing antifreeze power supply are same power supply.
