Power cable having end connecting portion

A power cable with a termination connection box, the power cable comprising a conductor, an inner semiconducting layer, an insulating layer, and an outer semiconducting layer which are sequentially formed,

• wherein the insulating layer comprises composite insulating paper, wherein surfaces of the insulating layer which are in contact with the inner semiconducting layer and the outer semiconducting layer are wound with insulating paper including only kraft paper, and
• the composite insulating paper has a structure in which the kraft paper is stacked on top and bottom surfaces of thermoplastic resin, and
• wherein the termination connection box comprises:
• a porcelain tube configured to provide an inner space into which an end portion of the power cable from which portions of the outer semiconducting layer, the insulating layer, and the inner semiconducting layer are sequentially removed is inserted;
• and
• a reinforcing insulating layer configured to cover an outer side of the insulating layer of the power cable so as to reinforce dielectric strength of a portion of the power cable from which the portion of the outer semiconducting layer is removed and at which an electric field is thus concentrated,
• wherein the reinforcing insulating layer comprises the same insulating paper as an outermost layer of the insulating layer of the power cable.
