Abstract:
1. A method for spacing electrical power cables, comprising: supporting a first electrical power cable and a second electrical power cable with a plurality of first plastic duct spacers, each duct spacer of the plurality of first duct spacers having two upward facing openings for supporting the first and second electrical power cables and spaced horizontally from adjacent duct spacers of the plurality of first plastic duct spacers; and supporting a third electrical power cable with a second plurality of second plastic duct spacers, each second plastic duct spacer of the second plurality of second plastic duct spacers spaced horizontally apart from adjacent second duct spacers of the second plurality of second plastic duct spacers and having two openings facing downward and an opening facing upward, the two openings facing downward for containing and spacing the first and second electrical power cables and the opening facing upward for supporting the third electrical power cable, wherein the third electrical power cable is directly above or below and adjacent the first power cable and wherein the three openings of each second duct spacer of the second plurality of duct spacers are adjacent one another and in contact through a plurality of ribs with no intervening openings, and wherein centers of the three cables approximate an equilateral triangle having a vertical base formed by the centers of the first and third cables, wherein an arrangement of energized electric power cables in a form of an equilateral triangle with no intervening cables is effective to reduce electromagnetic force (EMF) emanation from the energized electric power cables.
