<p>PROBLEM TO BE SOLVED: To suppress staggered centers of the insulations of respective power cables to be connected in a joint part, and make interfacial surface pressures between stress relief cones and the insulations uniform. SOLUTION: A prefabricated joint has an epoxy unit 1 put onto the outer circumference of a conductor connection part and stress relief cones 2, which are inserted into the ends of the unit 1 and out onto the outer circumference of the insulations 5 of power cables. Conductors 3 are connected to each other by the used of anchor sleeves 8 connected to the respective conductors 3 and a case 9, in which the respective anchor sleeves 8 are slidably housed. The anchor sleeves 8 are coupled with the case 9 so as to be able to slidable relative with respect to the case 9 freely, a discrepancy between the axes of the respective conductors 3 can be absorbed by the sliding actions of the anchor sleeves 8 and the bending action of a wire 7, so that the axes of the insulation can be made to coincide with each other, and surface pressures between the stress relief cones and the insulations are uniformized.</p> |
