Numerical Simulation Results and Laws of Transmission Lines Ice-melting

Based on the numerical simulation model of icing, the impact on icing of the current was further investigated. The critical current value with the meteorological conditions of foreign objects, as well as the physical parameters of the aerial cable itself change the law. The calculation results showed that the critical current value depends on the external weather conditions and the aerial cable itself, the physical parameters, and the critical current and the ambient temperature, wind speed, relatively good linear relationship.
