Aluminum alloy high-voltage extraordinary power cable

The utility model discloses an aluminum alloy high-voltage extraordinary power cable. The cable core includes a plurality of intertwisted conductors, a conductor shielding layer, a crosslinked polyethylene insulating layer, an insulation shielding layer and a waterproofing tape winding cladding layer. The outside of the cable core is clad with a wrinkle aluminum alloy sheath layer, a PVC sheath layer and a graphite semi-conduction layer in consequence, wherein the wrinkle aluminum alloy sheath layer is welded with the cable core. In the utility model, the high-melting point of the aluminum alloy material is utilized to play the heatproof effect, which solves the problem that the high-voltage cable is required to be used in an environment with a high temperature; not only good heatproof characteristic is possessed, but also excellent electrical performance is possessed; the service life of the cable is prolonged; and the generation probability of an accident is reduced.
