METHOD FOR MAKING AN ELECTRIC INSULATOR WITH A POLYMER COATING CONTAINING ANTIOZONANT AGENTS

摘要

A method of fabricating a composite insulator with a protective housing made of a polymer material incorporating an antioxidant and an antiozonant includes the step consisting in incorporating said antiozonant at a final concentration by weight lying in the range 0.005% to 1%, and said antioxidant at a final concentration by weight lying in the range 0.005% to 1%, said antiozonant being selected from the family of phenylenediamines, and said antioxidant being selected from the family of multifunctional phenolic antioxidants.
