Abstract of the Disclosure A priorly used three layer insulation covering for conductors forming a drop wire for connecting aerial distribution cables to subscriber's premises is replaced with a single layer of insulation which includes a reaction product of a mixture comprising polyvinyl chloride, a non- brominated unmodified epoxy resin, a plasticizer, a metallic stabilizer, a filler system, a flame retardant constituent and a carbon black constituent. The reaction mixture is extruded about a pair of conductors which have been preheated within a suitable temperature range. The tempera- ture of the conductors causes a reaction with the reaction mixture that has a reproducible permanent adhesion to the condutors.
