[0001] The utility model relates to the technical field of aluminum alloy cables, in particular to a corrosion-resistant and mildew-resistant aluminum alloy cable for offshore wind power. Background Art

[0002] Aluminum alloy cables add copper, iron, magnesium, silicon, zinc, boron and other alloy elements to electrical aluminum. At the same time, through process adjustment, the mechanical properties of aluminum alloy conductors are greatly improved, avoiding the problems of low elongation, poor creep resistance and poor flexibility of pure aluminum conductors, and increasing the connection reliability of cable systems. In addition, to keep the electrical properties of aluminum alloys on par with electrical aluminum conductors, at more than 61% IACS, aluminum alloy cables in the prior art usually use layers of wrapping to protect the inner core of the cable.
