| description | The utility model provides a tramcar power cable, which comprises a sheath, a cable main body and a filling layer arranged between the sheath and the cable main body, the sheath sequentially comprises an outer sheath and an armor layer from outside to inside, and an inner sheath is selectively arranged between the armor layer and the filling layer. The cable body sequentially comprises a copper conductor, an insulating layer and a metal layer from outside to inside. The power cable sheath has the beneficial effects that the power cable sheath has higher heat resistance and ageing resistance, and the thermal extension performance can be tested; each copper conductor is formed by pressing and twisting more than one strand of special-shaped copper wires, almost no gap exists between the copper conductors, the surface electric field of the copper conductors is balanced, the heating is small, and the current-carrying capacity of the conductors is improved.
