OVERHEAD ELECTRICAL CABLES AND METHOD FOR FABRICATING SAME
A bare overhead electrical cable and a method for the manufacture of an overhead electrical cable. The electrical cable includes a central strength member and at least two conductive layers surrounding the strength member, the two conductive layers being formed from first and second conductive strands respectively. The first conductive strands are formed from first aluminum material and the second conductive strands are formed from a second aluminum material, where the second aluminum material has at least one material property that is different than the same material property of the first aluminum material. For example, the second conductive strands may be formed from an aluminum material having a lower conductivity but higher hardness than the first aluminum material. Such a configuration may be useful when the overhead electrical cable is installed in a geographic region that is subject to heavy ice loading.
