Copper conductor insulated overhead cable

The utility model discloses a copper conductor insulated overhead cable, which comprises a protective layer and is characterized in that an anti-corrosion layer is adhered to the inner wall of the protective layer; a temperature-resistant layer is attached to the inner wall of the anti-corrosion layer; the center of the protection layer is provided with a main tensile core; a crossed insulating layer is arranged by taking the main tensile core as a circle center; the inner cavity of the protective layer is divided into four chambers by the insulating layer; copper conductors are arranged in the cavities; a plurality of tensile cores are arrayed on the outer side of the copper conductor; and the filling layer is arranged in the gap between the copper conductor and the secondary tensile core in the cavity, so that the cable is resistant to pulling and can form a protection layer for the internal cable cores, and the risk of accidents caused by adhesion of the internal cable cores when the weather is too hot or
