  A silicone rubber composition, comprising: (A) an polyorganosiloxane gum represented by the following average structural formula: RaSiO(4-a)/2 (where R is a substituted or non-substituted monovalent hydrocarbon, and a is a number between 1.8 and 2.3); (B) microparticulate silica; and (C) a methyl-substituted benzoyl peroxide having the maximum grain diameter not exceeding 50 µm and an average grain diameter of 30 µm. When cured, the silicone rubber composition has reduced nonuniformity in the physical properties because of fewer voids, resulting in decreased frequency of spark-outs in the insulated wires.
