Waterproof multi-pair telephone cable with improved filling compound

摘要

This specification relates to a communication cable and method of making it, particularly where the cable includes a high pair count with small conductors so that the filling compound can be made to permeate to the center of the cable without having the filling compound become too viscous to reach the center of the cable when filled by the liquid filling process. The filling compound does not drip at temperatures up to 90 DEG C. From five to ten parts by weight are used of a polyethylene compound as one ingredient of the filler material. The major ingredient of the filler is a paraffinic oil which constitutes 100 parts of the filler compound. Other important considerations are to formulate the compound so that it will not permeate into the cells of the foam skin or all foam insulation.
