Soft aluminum alloy cable for tower drum of wind power generation system

The utility model relates to the technical field of power cables, in particular to a soft aluminum alloy cable for a tower drum of a wind power generation system, which comprises a cable core, the cable core comprises a plurality of conductor wire cores tangent in pairs and a filling layer filled among the plurality of tangent conductor wire cores, and the conductor wire cores and the filling layer are wrapped by a wrapping layer to form a circular cross section; and the first braided layer is braided on the outer wall of the wrapping layer. According to the utility model, the talcum powder is filled at the joint surface indirect part of the conductor wire core and the filling rope, and the filled foaming strip is used as a deformation space, so that when the cable is twisted and bent, the friction and bending stress between the sheaths are reduced, the conductor wire core can be twisted into the cable by using a large pitch, and the weight and the cost of the cable are reduced. 本实用新型涉及电力电缆技术领域，具体而言涉及风力发电系统塔筒
