Abstract
A cable and method of forming the cable are presented. The cable contains twisted wire pairs disposed in a cavity defined by a jacket. Each wire has a conductor and an insulator surrounding the conductor. The cable may also contain a spline that separates 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. The jacket may contain corrugations after being extruded by the extruder. The cable may be passed through dies to form a helically corrugated jacket. The jacket heated by a heater prior to being passed through the dies, or may pass through the dies while still hot from the extruder.

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;
- extruding a jacketed cable from the extruder, the jacketed cable containing the twisted wire pairs disposed in a cavity defined by a jacket;
- and
- passing the jacketed cable through dies to form a helically corrugated jacket,
- wherein at least one of:
- the helically corrugated jacket is corrugated such that cored ridges extend outwardly from the conductor to form an air gap that extends from the cavity, or
- at least one of the insulators is corrugated such that cored ridges extend outwardly from the conductor to form an air gap that extends from the conductor associated with the insulator.
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;
- and
- 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,
- wherein at least one of:
- the spiral jacket is corrugated such that cored ridges extend outwardly from the conductor to form an air gap that extends from the cavity, or
- at least one of the insulators is corrugated such that cored ridges extend outwardly from the conductor to form an air gap that extends from the conductor associated with the insulator.
