NOVELTY - The utility model claims an energy-saving high-conductive aluminium alloy cable, comprising a cable core, the cable core is orderly provided with a semi-conductive lapping belt, an isolation layer, an armour layer and an outer protecting layer, the cable core is composed of three high-conductivity aluminium alloy wire core twisted together; and round by filling layer is filled in the gap of the three high-conductivity aluminium alloy wire core, each high-conductivity aluminium alloy wire core is composed of the aluminium alloy conductor, graphene of three-layer coextrusion composite semi-conductive conductor shielding, an insulating layer and a graphene composite semi-conductive insulating shielding. and wrapping the metal shielding layer is formed by using aluminum alloy instead of copper, the better performance of graphene composite semi-conductive material, the inner and outer shielding has a relatively small volume resistivity, the homogenizing effect of the electric field intensity, and also reduces the weight of the cable, which is energy-saving, low cost and so on.
