  • Patent number: 4128736
    Abstract: While randomized splicing of twisted conductor pairs within groups in pulp cables is generally desirable to avoid electrical degradation resulting from systematic additions of capacitance unbalances, restoration of such cables, when severed, requires identification of each conductor pair for splicing. A cable design with a restoration color code has been developed which features groups having a manageable number of conductor pairs for identification splicing. Each group comprises several conductor pairs which have unique color combinations and which are precisely arranged in the group so the remaining conductor pairs having repeating color combinations can be identified by position relative to the uniquely colored pairs.
