Abstract
A method of manufacturing a cold shrinkable termination for an electric power cable that includes an insulation tube and stress control glue. An electric power cable is provided having an exposed end including: a conductor core having an exposed portion and an unexposed portion; an insulation layer having an exposed portion and an unexposed portion covering the unexposed portion of conductor core; a semi-conductive shield layer having an exposed portion and an unexposed portion covering the unexposed portion of the insulation layer; a metal shield layer having an exposed portion and an unexposed portion covering the unexposed portion of the semi-conductive shield layer; and an outer protection layer covering the unexposed portion of the metal shield layer. A cold shrinkable termination is provided including: an insulation tube; a stress control glue; and, a support tube. The stress control glue is coated along a selected segment of an inner wall of the insulation tube. The insulation tube of the cold shrinkable termination is expanded on the support tube. The exposed end of the electric power cable is inserted into the support tube, and the support tube is removed from the insulati…
