A composite reinforced electrical transmission conductor primarily designed for transmission of electrical signals. The conductor is comprised of a reinforced plastic composite inner core along with an outer highly electrically conductive sheath therearound. In this way, the inner core provides the necessary strength and the outer sheath provides for transmission of the electrical signals. In a preferred embodiment, the reinforced composite core is comprised of individual sections which cooperate together to provide the necessary loading capabilities. Further, a fiber optic cable may also be carried by the composite reinforced core. A splicing arrangement for securing ends of the cable together is also provided.
