摘要： A power cable with a termination connection box. The power cable includes a conductor, an inner semiconducting layer, an insulating layer, and an outer semiconducting layer which are sequentially formed. The termination connection box includes: 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.
