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 secondconductive strands are formed from a second aluminum material, wherein 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. 裸露架空电缆和制造架空电缆的方法。电缆包括中心强度构件和围绕强度构件的至少两个导电层，这两个导电层分别由第一和第二导电股线形成。第一导电股线由第一铝材料形成，第二导电股线由第二铝材料形成，其中第二
