• An Assessment of Polyethylene Insulator Performance

    Porcelain insulators have proven to be unsuitable for insulated conductor applications, simply because the difference in dielectric constants between porcelain and polyethylene will eventually lead to electrical erosion of the polyethylene cable insulation. To solve this problem, electrical engineers are now considering insulators manufactured from high-density polyethylene that is compatible with polyethylene-insulated wire.
