Abstract
This disclosure teaches a suspension insulator comprised typically of a fiberglass rod with mounted metal hardware at each end and juxtaposed polymer sheds strung thereon, which insulator has been improved for high voltage application. Above system voltages of about 138 kV, undesirable radio noise and corona occurs in the area of the metal hardware in conventional designs. Addition of semiconducting polymers between the metal hardward and the polymer sheds significantly reduces the level of generated radio noise and eliminates the corona.
