Mechanical and Electrical Properties of Overhead Conductor due to Forest Fire

Forest Fire can cause a serious damage to overhead conductors. Therefore, the detailed investigation for the changes of mechanical and electrical properties of damaged conductors should be carried out to understand the effect of forest fires on conductors. This is very much important to maintain transmission line safely. Especially, this paper describes the changes of mechanical and electrical properties of flame exposed conductor. Overhead conductors temperature were almostly 5565% of ambient temperature. Tensile Strength decreased according to incerase of Forest Fire temperature. The detailed will be given in the text.
