An electrical power cable having improved conductivity, better compaction of electrical conductor material within the space available in the cable for electrical conductor material, and reduced distribution losses is provided. In one embodiment, the electrical power cable includes at least one conductor component, said at least one conductor component further includes compactly packed trapezoidal cross-section aluminum strands which are prepared from high electrical conductivity aluminum. In detail, firstly, said high electrical conductivity aluminum is obtained by treating molten aluminum with boron for removal of electric conductivity decreasing impurities. Thereafter, aluminum rod/s is/are prepared from high electrical conductivity aluminum. In the next step, trapezoidal cross-section strands are obtained from the aluminum rod. Finally, obtained trapezoidal strands are annealed under controlled conditions to further improve their electrical conductivity. To further enhance the overall electrical conductivity of the electrical power cable, the trapezoidal cross-section strands are packed very compactly within the cable. |
