Abstract
A cable for use in a high-frequency current feeding equipment constituted by passing an inner bundle (A) of wires ( ) disposed at the same distance from the center of multiconductor cable ( ) and outer bundles (B and C) of wires ( ) through a ferrite ( ) in such a way that the ampere-turns thereof are the same. The counter-electromotive force generated because of the difference of the spatial arrangement between the inner wires ( ) and the outer wires ( ) caused when stranded is canceled, and the current phases and current values of the wires ( and ) are forced to be exactly the same. Therefore, an increase in the resistance due to the proximity effect is prevented, and thereby the multiconductor cable ( ) can be used as a high-frequency current cable.
