In parts by weight, every 100 parts of said rubber matrix comprise: 50-95 parts of a chlorinated (and/or chlorosulfonated) polyethylene rubber, 5-50 parts of a highly branched polyethylene, and 0-30 parts of an ethylene propylene rubber; and, the branching degree of the highly branched polyethylene is not lower than 50 branches/1000 carbon atoms. The compounding components contain a vulcanization system. The rubber composition improves the electrical insulation performance of the chlorinated (and/or chlorosulfonated) polyethylene rubber, so that the rubber composition is more suitable for the applications with high requirements for electrical insulation.
