Abstract:
1. A method of forming a cable, the method comprising: feeding twisted wire pairs into an extruder, each wire of the twisted wire pairs including a conductor and an insulator surrounding the conductor; feeding a spline into the extruder; combining the spline and twisted wire pairs in the extruder; extruding a jacketed cable from the extruder, the jacketed cable containing the combination of the twisted wire pairs and spline disposed in a cavity defined by a spiral jacket, and at least one of the insulators is corrugated such that the cored ridges are adjacent to the conductor and extend outwardly from a surface of the conductor to form an air gap that extends from the conductor; and varying a rotation rate of a die located at an end of the extruder and an extrusion velocity of the jacketed cable to vary a pitch of depressions of the spiral jacket.
