Abstract
Embodiments of the invention provide self-regulating heater cables utilizing substantially solid polymeric buffer layers surrounding the heating elements having improved heat transfer efficiency as well as improved reliability and endurance. The assembly includes first and second power supply wires configured to carry electrical power and separated by a solid spacer, a substantially solid electrically-insulating buffer layer in thermal contact with the heating element, and a cable jacket including a polymeric outer surface and an inner metallic sheath surrounding the buffer layer and in thermal contact with the buffer layer. The buffer layer includes a polymeric material having a thermal conductivity greater than air at standard temperature and pressure and surrounds the heating element, power supply wires, and spacer.
