De-icing Method for Coupled Transmission Tower-Line System
Energy Procedia, 2012 AbstractFor the disaster brought by the transmission line regelation, a new de-icing method is presented in this paper. It is supposed that the ice and transmission line are combined closely when there is no external loads, the composite structure of ice-transmission line is set up, then the coupled model of the composite structure-tower is set up.
