ABSTRACT:
Cable splices of outside telephone plant are rehabilitated by a method in which a length of tubing of a kit of parts is moved over end portions of cables which are to be respliced, if necessary. The tubing is collapsed adjacent jacketed portions of the cables and a collar comprising a plurality of turns of sealing tape is formed about the jacket of each of the cables in adjacent locations. A spacer block is positioned between the collars to maintain the cables spaced apart after which a liner made of a perforated, transversely corrugated strip of plastic material is wrapped about the splice. The tubing is extended over the liner and its lower end is taped about the collars to form a closed end to prevent the escape of a waterproofing material which is flowed into the opposite open end of the tubing. A length of transversely and longitudinally scored plastic is wrapped about the tubing and cut along one of the score lines to form a cover which is secured by a plurality of clamps. The enclosed encapsulated splice is generally formed within a pedestal cabinet or adjacent a telephone pole in which case it is protected mechanically by a metallic U-shaped guard that is positioned over the cover along its length and secured to the pole.
