Dynamic Characteristic of Conductor After Ice-Shedding and Simulation Analysis of the Tension Insulator String

Electric power fittings are the link between conductors and transmission towers, it is essential to improve their ability withstand damage. In order obtain actual load of electric study stress each fitting under load, a line model catenary-shaped an integral tension insulator string established in this paper. Then, with uniform thickness ice coating shedding process simulated by changing density method. The results show that maximum dynamic conductor isolated span greater than static icing only when length ice-shedding section small. Under any condition, multi-span will be close or after icing. When form loaded on string, can found most dangerous secondary found, analysis carried out key connecting fittings, which provides reference for design optimization fitting.
