Title: Hollow twisted and drawn cables and method for making the same

Abstract: Electrical cables of the present invention include cables made from plated filaments which are first twisted together and then drawn through reducing dies (or swaged). The cables exhibit a conductivity comparable to cables having greater diameter and weight. The smaller diameter of the cables of the invention allows them to be used as leads for electronic components in order to achieve reduced parasitic capacitance without increased resistivity or reactance or component package size. The cold working of the cables of the invention provides them with enhanced flexibility and fatigue strength. The combination of materials used in the cables of the invention provides them with resistance to corrosion and the adverse affects of aging as well as enhanced conductivity. Cables formed according to the invention with a hollow tube core can be self-cooling, or easily cooled by flowing coolant through the hollow core.
