Abstract
A method for delivering a geometric type stress relief element to a terminated electrical cable is provided. The cable contains a conductor surrounded by at least one coaxial layer of insulator, semiconductor, grounded wires and cable jacket. First, the terminated cable is tapered to expose a portion of the conductor so as to protrude beyond the insulation, which protrudes beyond semiconductor, which protrudes beyond the conductive wires. A geometric stress cone is preloaded onto a cold shrink tube. The terminated, tapered cable is inserted into the cold shrink tube. The cold shrink tube is removed and the geometric stress cone collapses onto the tapered cable. The cable is rated for supplying high voltage.
