Abstract
An electrical power cable includes a central support or a ground conductor surrounded by an insulating material layer. An inner grounded shield is disposed on the support or on the ground conductor. A plurality of insulated line conductors and a plurality of insulated neutral conductors are circumferentially disposed in an annular arrangement about an insulation layer on the inner shield. The plurality of line and neutral conductors are disposed in various alternating single, double or triple conductor groups. The total cross-sectional area of all of the line conductors or all of the neutral conductors is substantially equal to the total cross-sectional area of a single large conductor of equivalent ampere rating. An outer shield is disposed about the line and neutral conductors and covered by an outer insulating layer.
