Problems solved by technology

The cable structure provided by this technical solution is complex, and copper wire is used as the conductor, making its production cost relatively high. At the same time, when it is used at sea for a long time, it is easy to breed mold and affect product performance and appearance.
[0007] With the rising price of copper, replacing copper with aluminum is an inevitable trend in the development of wire and cable. However, in the prior art, when the aluminum alloy monofilament is used as the cable core, it is easy to break the wire during the twisting process of the cable.
Therefore, how to solve the problem that the aluminum alloy monofilament is easy to break during the twisting process of the cable, and provide a cable with good salt spray resistance and mold resistance, so that it can be used as a wind power generation cable, has become an urgent problem to be solved. technical issues

Abstract

The invention provides a compound stranded aluminum alloy cable and a preparation method and application thereof. The compound stranded aluminum alloy cable sequentially comprises a conductor, an insulating layer and a sheath from inside to outside along the radial direction, wherein the conductor is formed by twisting one central unit and six peripheral units in the left direction, and the central unit is located in the center of the peripheral units. The central unit is formed by leftwards twisting one steel wire rope and six category 5 aluminum alloy strands, and the steel wire rope is located in the center of the category 5 aluminum alloy strands; the peripheral unit is formed by leftwards twisting seven category 5 aluminum alloy strands; and the five types of aluminum alloy strands are formed by twisting 30-40 aluminum alloy monofilaments in a rightward bunching manner. The compound stranded aluminum alloy cable provided by the invention has relatively good torsion resistance, flame retardance, salt spray resistance and mildew resistance, and is suitable for being used as a cable for wind power generation.
