Embodiment Construction
[0016] Such as figure 1 As shown, a 1kv aluminum-core overhead cable according to the present invention includes two parallel cables with the same vertical structure, and the two cables are connected by a plurality of connecting ribs 4; the cables include a cable core , the outer sheath 5 extruded outside the cable core and the plastic cooling pipe 6 arranged outside the outer sheath, the plastic cooling pipe 6 is provided with cooling liquid, the heat transfer through the wall of the cooling pipe will be in the entire circumference of the cooling pipe The surroundings are balanced, and the effective heat transfer to the cooling liquid arranged in the cooling pipe is realized, so that the overall heat of the cable is reduced and the skin effect is reduced; the cable core is composed of a carbon fiber filament 3 and a parallel symmetrical carbon fiber It consists of two aluminum wires on both sides of the wire.
[0017] Wherein, the aluminum wire is composed of an aluminum con...
