In accordance with embodiments of the present disclosure, a cable system for conveying well servicing equipment into a wellbore includes a core support structure extending longitudinally along an axis of the cable system. The core support structure comprises polymer reinforced with fibers, and the fibers are oriented substantially parallel to the axis of the cable system. The cable system also includes a mesh layer disposed around and bonded to the core support structure. The mesh layer includes metal wrapped around the core support structure. The cable system also includes a polymeric coating disposed around and bonded to the mesh layer. The mesh layer enables increased structural support of the cable system, particularly against forces in the radial direction relative to the axis of the cable system. In some applications, the mesh layer acts as a return conductive path for conductors embedded in the core support structure.

A flange assembly for supporting a cable has a flange body and an armor retainer. The flange body and the armor retainer are configured to support a cable by compressing an armor layer of the cable against the armor retainer. The armor retainer and the flange body are separate pieces, that are removably attachable to one another.

The present disclosure relates to a cable that includes a core, a first armor wire layer surrounding the core, a first polymer layer disposed around the first armor wire layer, where the first polymer layer has a first sensitivity to energy emitted from an energy source, a second armor wire layer that may be disposed at least partially in the first polymer layer, and a second polymer layer disposed around the second armor wire layer, where the second polymer layer has a second sensitivity to the energy emitted from energy source, and the second sensitivity is greater than the first sensitivity.

A power cable for an electrical submersible well pump has at least one insulated conductor and an armor strip wrapped in helical turns around the conductor. The armor strip has a steel layer and a first polymer layer bonded to a first side of the steel layer. Each of the helical turns of the armor strip overlaps with another of the helical turns, causing the first polymer layer of each of the helical turns to form a seal with of a next one of the helical turns. A second polymer layer may be bonded to a second side of the steel layer. The second polymer layer of each of the helical turns overlies in sealing contact with the first polymer layer of the next one of the helical turns.
