Composite distribution cable

Claim 1

A composite cable for the transmission of electrical signals comprising: a longitudinally extending core member having a metallic conductor member for transmitting broadband signals encased within an insulating member, said core member having an outer surface and a longitudinal axis: first and second insulated electrical power conducting members disposed substantially adjacent each other and extending longitudinally along said outer surface; a twisted pair of individually insulated narrow band signal conductors disposed adjacent the outer surface of said core member on the other side of the axis thereof from said power conducting members and extending longitudinally therealong; a jacket of insulating material surrounding said core member, said power conducting members and said twisted pair, said jacket being spaced from said core member; means for preventing the flow of water into and through at least a portion of the space between said core member and said jacket, said means comprising one or more discrete superabsorbent members located in the space between said core member and said jacket and extending along the length of said cable; a first metallic sheath member surrounding said insulating member in contact therewith said cable further comprising a second metallic sheath member surrounding said core member and spaced therefrom, said power conducting members, said twisted pair, and said superabsorbent members being situated in the space between said first and second metallic sheath members.
