Patent abstract
A cable and method of forming the cable are presented. The cable contains twisted wire pairs having a conductor and an insulator surrounding the conductor. A jacket surrounds the twisted wire pairs. At least one of the insulators or the jacket is helically corrugated such that ridges extend radially inward or outward. The ridges of the insulators may be the same or different. The cable is extruded from an extruder or heated by a heater. The heated cable is then passed through vacuum-forming dies to form the desired spiral-convoluted shape.
