Abstract

Embodiments of the invention include a flute (16), a fluted electrical cable (10) and a method for making. The flute (16) is made of a perfluoronated resin such as FEP and is configured with webs (24) arranged to separate conductive elements within the cable. The thickness (T) of the individual webs is approximately 10 mils to approximately 30 mils, the overall width (W) of the flute from the tip of one web to the tip of an opposing web is approximately 120 mils to approximately 170 mils, and the weight per unit length of the flute is less than approximately 6.0 grams per meter (g/m). The flute is foamed or, alternatively, is made with melt fractured. The fluted electrical cable (10) includes a plurality of paired conductors (14), a dielectric jacket (12) formed around the paired conductors, and the inventive flute (16) configured to separate the paired conductors within the dielectric jacket. The method for making the electrical cable includes providing the paired conductors, combining the paired conductors with the inventive flute, and forming a protective dielectric jacket around the paired conductor/flute combination. In one embodiment, the method includes forming a foamed flute. In an alternative embodiment, the method includes forming a melt fractured flute, for example, by extruding the perfluoronated resin at an extrusion rate that exceeds the critical shear rate for such material.
