Abstract
A power cable having a central ground conductor. Phase interweave power conductors are positioned about the central ground conductor. Individual phase interweave power conductors have the same diameter. The individual phase interweave power conductors have a cross sectional area which is optimized. Each of the individual phase interweave power conductors is configured to support 100% cross sectional usage to maximize power carrying capability. The power cable reduces the skin effect of the power cable and the proximity effect of the power cable.

A power cable comprising:
- an outer shell;
- a plurality of individual power conductors positioned in the outer shell, the individual power conductors having a cross sectional area which is optimized wherein the individual power conductors have the same diameter and each individual conductor being configured to support 100% cross sectional usage to maximize power carrying capability;
- wherein the individual power conductors of the plurality of individual power conductors are arranged in phase groupings with fillers provided between the phase groupings;
- wherein the diameter of each of the individual power conductors of the individual power conductors is proximate to, but below, the skin effect cutoff diameter of the respective individual power conductor of the individual power conductors for the maximum operating frequency of the power cable;
- wherein the individual power conductors reduce the skin effect;
- and
- wherein the individual power conductors are arranged in a phase interweave, the phase interweave cancels the electrical proximity effect, minimizing the effective resistance of each of the individual power conductors.
