Abstract

An unshielded buried service wire includes a core and a jacket. The core comprises two pairs of insulated metallic conductors. Also associated with each conductor pair is a longitudinally extending waterblocking member which inhibits the flow of water longitudinally of the wire. The jacket has a transverse cross sectional configuration which is generally oval.
Adjacent to each of opposed small radius of curvature portions of the service wire and embedded substantially in the jacket is a longitudinally extending, rod-like strength member which is caused to adhere to plastic material of the jacket.
