Abstract
Abstract A splicing technique for connecting armored-and-jacketed cables is described. The method is particularly useful in regard to submarine cable. Single- and double-armored cables, which may or may not be caged, are spliced in such a manner as to restore the splice to the strength of the original cable. The splice itself consists of several splice positions, and the wires and splice areas are completely embedded in a rubberlike material before the outer jacket is restored.

Total Claims: 31
Claim 1
Independent Claim
201 words
A splice between two elongated cable sections, where each cable section includes an elongated core member, one or more separate layers, each separate layer being comprised of a plurality of elongated strength members concentrically arranged around the core member, and an outer jacket of thermoplastic or other suitable material, comprised of: a. the elongated core members of the two cable sections attached mechanically to each other in an abutting position; b. the plurality of elongated strength members of each separate layer of one of the cable sections terminated at least at two different positions along the length of the cable section and attached mechanically to the corresponding elongated strength members of each separate layer of the other cable section which have been terminated at the same positions to accomplish the matings, where the outer jacket of each cable section has been removed back to a suitable position, whereby there is sufficient space to splice one cable section to the other; c. an elastomeric substance embedded around the elongated strength members and the various attachment positions; and d. a continuous outer coating distinct from said elastomeric substance covering the entire area of the cables from which the outer jacket has been removed.
