<p>PROBLEM TO BE SOLVED: To improve a connection insulation performance at the side of an insulation thickness reduction power cable 2B when connecting, via tape winding insulation, a power cable 2A of which the cross section is fan-shaped, having predetermined insulation thickness and the insulation thickness reduction power cable 2B of which the insulation thickness is made thinner than that of the power cable 2A and the cross section is circular.SOLUTION: A stress cone 11 having a rubber elasticity contractive force is mounted only at the side of the insulation thickness reduction power cable 2B, and a connection tape winding insulator 15 is formed by winding an insulation tape around an outer circumference over a conductor connection 14 of both the cables, cable insulators 4A and 4B at both sides and an insulation cylindrical part 12 of the stress cone 11. To an interface of the insulation thickness reduction power cable 2B and the stress cone 11, in addition to the rubber elasticity contractive force of the stress cone 11, winding pressure of the insulation tape wound around the outer circumference of the insulation cylindrical part 12 of the stress cone is applied.</p> |
