Claim:
1. A method of making a down-hole cable, the method comprising: foaming, via a nitrogen gas injection process, a filler layer about an insulated conductor portion, the filler layer abutting and encapsulating the insulated conductor portion, wherein the filler layer is substantially a fluoropolymer; applying an armor shell to an exterior of the foamed filler layer; and after applying the armor shell, heating the down-hole cable, including the foamed filler layer and the armor shell, to a temperature in excess of 300° C., thereby increasing a foamed cell structure of the foamed filler layer such that a radial compressive force is exerted on an exterior surface of the insulated conductor portion and an interior surface of the armor shell with the foamed filler layer.
