Most of the electricity carrying wires near highways do not have a plastic covering like the wires used at homes because air is a bad conductor of electricity. Hence there is no substantial loss of energy during the flow of electricity in the overhead electric wires on the road and at homes, the plastic covering is used as insulator.
