The present invention discloses a load carried ice melting proposal applicable to splitting the transmission lines of a lead. The present invention adopts three-splitting lead in ice-coated tension resistance section to insulate three sub-leads of the three-splitting lead by a spacing rod so that three independent current circuits are formed. When the three-splitting lead is coated with ice, the three sub-leads are changed from parallel operation into serial operation by an isolating switch and a current guide plate which is arranged on a tension resistance tower wire jumper on two ends of ice-coated tension resistance section so that current on three sub-leads is increased to load current of three times, thereby realizing load carried ice melting for the transmission lines. The circuit principle is also applied to five-splitting lead in ice-coated tension resistance section. The current of the sub-leads is increased to load current of five times by changing the parallel operation into serial operation of the sub-leads to realize load carried ice melting. When the ice-coated tension resistance section adopts six-splitting lead, the six-splitting lead is divided into two three-splitting lead current circuits to realize load carried ice melting.
