Abstract
Systems, apparatus, and methods for stretching wireline cables are provided. Tension is applied to a wireline within an engagement zone, either while the wireline is static or moving. The tension may be stabilized using a capstan. The wireline may be heated, coated, cleaned, stabilized, bent, or combinations thereof.
Claims101
A system for stretching wireline cable, the system comprising:
- a cable payoff;
- a cable take-up;
- a cable positioner, the cable positioner positioned to engage a cable between the cable payoff and the cable take-up;
- and
- a cable tensioner, the cable tensioner positioned to apply a tension to a cable engaged with the cable positioner.

A stabilized wireline cable, the stabilized wireline cable comprising:
- at least one conductor;
- an insulator surrounding the at least one conductor;
- an inner armor layer surrounding the insulator;
- and
- an outer armor layer surrounding the inner armor layer;
- wherein a stabilizing material is positioned to fill void spaces between the inner armor layer and the outer armor layer.
The stabilized wireline cable material comprises grit.
