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.

Abstract: [Problem] A power cable polymer connector is provided which is lighter than when using a porcelain insulator and can exert a free-standing property to maintain the arranged position even if it is used horizontally. [Solution] A power cable polymer connector 1 includes a polymeric insulating tube 2 including a cable insertion hole 2a, 2b to allow an insertion of a stripped end 101 of a power cable 100. The polymeric insulating tube 2 further includes an insulation 20 including a polymer-based material, an embedded pipe 21 including a metal and embedded on an inner peripheral surface of the insulation 20 so as to face the end of the power cable 100, and an embedded flange 22 including a metal and a mounting surface 22c to be attached to another member, the embedded flange being embedded in the insulation 20 on the outer peripheral side of the insulation 20 so as to allow the mounting surface 22c to be exposed from the insulation 20.

Abstract: A power cable polymer joint includes a polymer protective layer including a cable insertion hole into which a stripped end of a power cable is inserted. The polymer protective layer includes an insulation including a polymer-based material, a semi-conductive portion including mainly a polymer-based material to relax an electric field at the end of the power cable, and a tubular member including a different material from the polymer-based material and extending on a rear-end side of the insulation and the semi-conductive portion. The insulation and the semi-conductive portion and the tubular member are integrally formed. The tubular member has an inner diameter more than an outer diameter of a non-stripped power cable.

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 protective layer including a polymer-based material as a main component, a smaller inner diameter than an outer diameter of the end portion before the insertion, and a first cable insertion hole tightly contacting the end portion upon the insertion, and an embedded pipe being embedded on an inner peripheral surface of the insulation protective layer near a tip of the power cable in relation to the first cable insertion hole so as to face the end portion, and including a metal and a second cable insertion hole having an larger inner diameter than the outer diameter of the end portion.
