ABSTRACT:
A class of torsionally-balanced submarine cables is disclosed which are highly coilable without exhibiting the undesirable tendencies of looping and kinking of its predecessors. Coilability is achieved in part by controlling the cable's torsional stiffness to bending stiffness ratio. Use of glass-reinforced polyester tape between and over the armor wires facilitates movement of the armor wire during coiling. The teachings of the present invention apply to cables experiencing strains in the elastic range.
