Abstract
A power cable polymer joint includes a polymeric insulator tube including a cable insertion hole into which a stripped end portion of a power cable is inserted. The polymeric insulator tube includes an insulation including a polymer-based material, an embedded pipe including a metal and embedded on an inner peripheral surface of the insulation so as to face the end portion of the power cable, and a first semi-conductive portion including mainly a polymer-based material and covering an outer peripheral surface of the embedded pipe.
