What material is used for insulation in power lines?



  1. 0 Votes

    Many overhead power lines are not insulated. They are connected to pyrex or ceramic insulators where the line meets a support pole, but many of the lines carrying electricity to our homes are steel cables high in the air that use surrounding air as insulation. Some cables are coated in a plasticized rubber material, offering protection to the cable itself from the elements.
