Description : What happens insulators when high voltage passes through transmission lines whether it breaks or lose it's insulating property?
Last Answer : I think it will breaks when it crosses breakdown voltage .
Description : Why are overhead transmission lines not insulated?
Last Answer : Insulators are useful to help separate electrical conductors when they come into physical contact. Overhead Transmission Lines Are Not Insulated: The overhead transmission line is carrying extreme high voltage and ... a whole lot of thick insulation to absorb the heat produced by such high voltage.
