Abstract
The present invention relates to an improved isolated core or insulated conductor with a low dielectric constant and reduced materials costs. Apparatuses and methods of manufacturing the improved isolated core or insulated conductor are also disclosed. Twisted wire pairs having first and second wires, each of the first and second wires including a conductor and polymeric insulator surrounding the conductor are also disclosed. The polymeric insulators have channels that run along the length of the conductor. The conductors have exterior surfaces exposed to gas within the channels.
