ferromagnetic Curie point

According to the situation that transmission lines are easy to ice and cause tower failure in winter,this paper mainly outlines the large current ice-melting method,the research and development of low Curie point magnetic material in deicing technology of transmission lines and points out the present problems and developing trend in the future.
