Abstract
An aerial service wire (20) includes a jacket (40) having a generally rectangularly shaped cross section and comprising a polyvinyl chloride plastic material. Enclosed by the jacket are two strength members (36--36) each of which includes a plurality of filaments and each of which is impregnated with a material which is compatable with that of the jacket. The strength members are disposed along an axis (42) of the cross section which passes through a geometric center through which a longitudinal axis (50) of the jacket passes. Conductors (30--30) which are individually insulated are disposed adjacent to the longitudinal axis with each strength member being disposed between the conductors and the outer surface of the jacket.
