Abstract

PURPOSE:To provide good electrical characteristics and fire retardant property and prevent generation of detrimental halogen gas at the time of combustion by furnishing the conductor at its periphery with a covering layer consisting of an admixture of polymer of ethylene type and magnesium hydroxide. CONSTITUTION:Conductor is provided at its periphery with a covering layer of a mixture of polymer of ethylene type and magnesium hydroxide subjected to surface processing by stearic acid. Here sole polymer or two or more types thereof are used as polymer of ethylene type, while magnesium hydroxide is used as fire retardant agent. Water absorption and moisture absorption are suppressed by performing surface processing of the magnesium hydroxide, and thereby drop of electrical characteristics are prevented.
