high power cable 200 is similar to the cable 100 shown in fig5 but is designed for the transmission of single phase dc electrical power as illustrated by the four conductors 220 222 224 and 225 each of the four conductors 220 222 224 and 225 is surrounded by an insulating layer 230 232 234 and 235 respectively each of the four conductors 220 222 224 and 225 are comprised of a conducting material such as a metal or alloy or any other conducting material utilized in the art each of the three insulating layers 230 232 234 and 235 is either a coating or layer solid or partial which is comprised of an electric insulator dielectric material as used in the art examples of such insulator materials include solid plastic foam plastic polyethylene teflon or the like each of the conductors 220 222 224 225 may be a single solid wire or multiple stranded wires that are twisted braided or otherwise arranged the high power cable 200 also includes a jacket covering or layer or shielding 236 or other type of shield to surround and effectively enclose the conducting layers 220 222 224 and 225 and the insulating layers 230 232 234 and 235 the high power cable 200 can also include additional insulation material within the jacket cover 236 the insulating layers 230 232 234 235 and or the inner space 238 between conductors within the cable 200 the high power cable 200 can also include shielding material.
