20130183177 | Tubing Encased Motor Lead - A system and methodology facilitates the supply of electrical power in a variety of harsh environments. The technique may utilize an electrical power cable having an insulator located around an electrical conductor. The insulator and the electrical conductor are positioned within a metallic tube. In a variety of applications, the metallic tube enables construction of the electrical power cable without an armor layer. A jacket is disposed between the insulator and the metallic tube and is designed to compensate for differences in thermal expansion between the materials. The jacket may be formed with gas pockets distributed therein to compensate for a different level of thermal expansion of the jacket relative to, for example, the metallic tube. | 07-18-2013 |
20130306348 | Artificial Lift Equipment Power Cables - A power cable for artificial lift equipment can include one or more conductor assemblies, each including a copper conductor, a conductor shield with resistivity less than about 5000 ohm-m surrounding the conductor, insulation, an insulation shield having a resistivity less than about 5000 ohm-m surrounding the insulation, a metallic shield surrounding the insulation shield, and a polymer barrier surrounding the metallic shield. Such a cable may include a jacket molded about the one or more conductor assemblies and optionally armor surrounding the jacket. Various other apparatuses, systems, methods, etc., are also disclosed. | 11-21-2013 |
20140027152 | Power Cable System - A technique facilitates the provision of electrical power in harsh environments, such as subterranean environments. The technique employs a power cable having at least one conductor and a polyimide insulation layer disposed about the conductor. A fluoropolymer tape layer is disposed about the polyimide insulation layer. The fluoropolymer tape layer is processed into a uniform, bonded layer. Additional cable layers also may be employed to help provide protection in the harsh environment. | 01-30-2014 |
