Abstract
A method of removing a metallic cable core that extends through an outer cable sheath of a length of data transmission cable is disclosed. The core is surrounded by a filler material contained within the outer cable sheath as an integral part of the cable. The method comprises the steps of resistively heating the core by supplying electric current to it to reduce the viscosity of the surrounding polymer material; and pulling the core out of one end of the outer cable sheath whilst the viscosity of the filler material is in a reduced state.

A method of removing a metallic cable core that extends through an outer cable sheath of a length of data transmission cable, the core being surrounded by a filler material contained within the outer cable sheath as an integral part of the cable, the method comprising the steps of:
- (a) resistively heating the core by supplying it with electric current to reduce the viscosity of the surrounding filler material;
- and
- (b) pulling the core out of one end of the outer cable sheath whilst the viscosity of the filler material is in a reduced state.
An apparatus for removing a metallic cable core extending through an outer cable sheath of a length of data transmission cable in which the cable core is surrounded by a filler material contained within the outer cable sheath as an integral part of the cable, the apparatus including an electrical generator for generating current and wires extending from the generator for connecting the apparatus to a cable core for supplying electrical current to the cable core, wherein the apparatus includes a housing containing the generator and an integral draw-string storage reel for supplying drawstring into the outer sheath following, or during, removal of the core.
An apparatus for removing a metallic cable core extending through an outer cable sheath of a length of data transmission cable in which the cable core is surrounded by a filler material contained within the outer cable sheath as an integral part of the cable, the apparatus including an electrical generator for generating current and wires extending from the generator for connecting the apparatus to a cable core for supplying electrical current to the cable core, wherein the apparatus includes a user operable elector for setting the amperage to be generated, and an amp meter connectable directly to the cable core to provide a measure of the actual amperage in the cable core.
