    摘要: An electric wire protection member covering and protecting an outer periphery of an electric wire, the electric wire protection member includes an exterior member made of a flexible resin and having a tubular body in which peak portions and valley portions are alternately formed in an axial direction over a peripheral direction orthogonal to the axial direction, and a tubular bending restriction member accommodated in the exterior member and capable of bending in one direction with one side portion as an inner side. The bending restriction member includes a cut-out portion and a plurality of divided tubular portions connected by a connecting portion formed in the one side portion. The cut-out portion is inclined in the axial direction with respect to a radial direction of the bending restriction member.

    摘要: High reliability power cables for subsea application are provided. Example power cables provide enhanced resistance to partial discharge dielectric breakdown as well as resistance to explosive gas decompression, by eliminating micro-defects and voids at the interface between the insulation layer and the barrier layer during the cable manufacturing process. Lead metal, which is conventionally extruded as a primary barrier layer, is replaced in the example power cables by a gas-and-fluid-resistant thermoplastic that is co-extruded or tandem extruded with surface-modified insulation to promote bonding between the two layers. Elimination of lead metal in the example power cables also significantly reduces their overall weight. The improved resistance to partial discharge and resistance to rapid gas decompression translates to lower workover and lower cost of ownership.

    摘要: 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 foamable fluoropolymer. At least one additive is mixed with the foamable fluoropolymer filler layer. An armor shell is applied to the exterior of the foamable fluoropolymer filler layer with the at least one additive. A bond is formed between the foamable fluoropolymer filler layer with the at least one additive and an internal surface of the armor shell.
