Cable terminal structure and method for forming the same

Abstract

The present invention provides a cable terminal structure that allows for the easy attachment of an electric field mitigation member and an insulating sheath without requiring skilled workers, and that prevents the concentration of electric fields near the electric field mitigation member. [Solution] The cable terminal structure 1 comprises a power cable 10, a terminal 2 having a connection portion 21 connected to the stripped portion of the conductor 11 that constitutes an end portion 10a formed by stripping the conductor 11, insulating layer 12, and outer semiconducting layer 13 of the power cable 10 so that they are sequentially exposed, an electric field mitigating member 3 covering at least the stripped portion of the outer semiconducting layer 13 and insulating layer 12, and an insulating outer sheath 4 that closely covers at least the outer surface portion from the electric field mitigating member 3 to the connection portion 21, wherein the electric field mitigating member 3 has an electric field mitigating portion 31 that closely covers at least the stripped portion of the outer semiconducting layer 13 and insulating layer 12, and an insulating portion 32 extending from the electric field mitigating portion 31 to the end side of the power cable 10, and the dielectric constant of the electric field mitigating portion 31 is higher than that of the insulating portion 32.
