US Patent 10186850 Non-metallic electrical cable support arrangement

An electrical cable support system for use with large diameter, heavy electrical cables disposed in confined spaces includes as least one support structure-mounted stanchion coupled to a generally triangular support bracket adapted for receiving and supporting one or more electrical cables. The coupling between the stanchion and support bracket allows for pivoting displacement of the support bracket on the wall-mounted stanchion to accommodate movement of the cables during electrical load cycling. The support bracket includes a first upper generally horizontal linear arm adapted for receiving and supporting one or more electrical cables, a second lower, inclined arm having plural steps proceeding downward toward the stanchion to provide an increased space below the support bracket to accommodate increased numbers of electrical cables. The support bracket is tapered along its horizontal and vertical axes to better distribute cable weight over the support bracket's entire length and height, and includes an inner apertured portion comprised of crisscrossed trusses for reduced weight and increased strength.
