| 摘要 |
A light-weight electrical conductor comprising a plurality of at least seven longitudinally extending and closely wound strands, some of the wound strands being formed substantially of copper and the remaining strands being formed substantially of an electrically conductive grade of aluminum. Each of the strands in the conductor has an exterior surface coating of an identical electrically conductive material, preferably taken from the group of silver, nickel or tin. The conductor includes a suitable insulating material such as Teflon or the like which forms an outer cover layer for the conductor. Preferably, the conductor includes either seven or nineteen strands, the seven-strand conductor having three strands formed substantially of aluminum and the remaining four strands formed substantially of copper, and the nineteen-strand conductor having seven centrally located strands formed substantially of aluminum and twelve peripherally disposed strands formed substantially of copper.
