PROBLEM TO BE SOLVED: To provide a cable terminal connection part in which flashover performance is enhanced through a simple structure while decreasing the number of components.;SOLUTION: The cable terminal connection part comprises a polymer bushing 26, and a cable terminal 28. The polymer bushing 26 comprises a hard insulation tube 16 having a central conductor lead-out rod 12 and provided with a cable receiving opening 14 at the lower end, a polymer coating 20 provided on the outer circumference of the insulation tube 16 and having a large number of ribs 18 formed on the outer circumference while spaced apart in the longitudinal direction, and a supporting metal 24 having a flange 22 projecting outward from the circumferential surface of the insulation tube 16. The cable terminal 28 is fixed to the cable receiving opening 14 of the insulation tube 16. The polymer coating 20 is located above the supporting metal 24 and the cable receiving opening 14 is located below the supporting metal 24. The flange 22 of the supporting metal 24 has curved surface at the corner 30 of the outer surface and a nonpenetrating threaded hole 34 is made in the lower surface part 32.;COPYRIGHT: (C)2006,JPO&NCIPI
