A system and method for a down-hole cable is provided. The down-hole cable includes an insulated conductor portion. A filler layer abuts and encapsulates the insulated conductor portion, wherein the filler layer is substantially formed with a foamed fluoropolymer. An armor shell is applied to the exterior of the foamed fluoropolymer filler layer.

A simplified process for producing a shield layer-cut electric wire that does not damage an insulating layer and a core wire and when cutting a shield layer.

A coaxial cable includes: a center conductor; a dielectric layer circumferentially surrounding the center conductor; and an outer conductor circumferentially surrounding the dielectric layer. The dielectric layer comprises an inner sleeve that circumferentially overlies the center conductor and an outer sleeve that circumferentially overlies the inner conductor. The outer sleeve contacts the inner sleeve to form a plurality of longitudinally-spaced seams to create a plurality of sealed segments along a longitudinal axis of the cable.
