Abstract

PURPOSE:To restrain the occurrence of a water tree by constituting an insulator via the application of a bridging process to a composition made from 100pts.wt. of polyethylene, ethylene system copolymer or the mixture thereof added with 0.005 to 1pt.wt. of a basic compound. CONSTITUTION:100pts.wt. of a mixture composed of polyethylene or one or more types of ethylene vinyl acetate copolymer, ethylene ethyl acrylate copolymer and the like are added with 0.005 to 1pt.wt. of a compound having the oxide and hydroxide of alkaline and alkaline earth metals, an amine compound or the compound thereof as constituents or impurities unable to be removed, and showing alkaline quality in the aqueous solution thereof. The aforesaid composition is subjected to a chemical bridging process using organic peroxide, an irradiation bridging process using ionized radial rays or a silane water bridging process using a silane compound. In the flame retardant electric insulation composition of the aforesaid constitution, a water tree generated due to voids and foreign materials in the insulator is restrained, thereby preventing a drop in insulation performance.
