Abstract

A cable for use in hydrocarbon wells is manufactured by forming an impervious sheet material to define a plurality of recesses, introducing each of two or more conductors into a respective one of the recesses, and folding the sheet material and joining two edges thereof to form a seam. The recesses form compartments, each enclosing a substantial portion of a respective conductor, so that the conductors are separated from each other by portions of the casing which extend in-between the conductors. In alternative embodiments, the casing can be made from plastics sheet material, or both the sheet material of the casing and the conductors may be made from copper clad steel so as to avoid differential thermal expansion, in which case the casing may simply enclose the bundled conductors without separating them into compartments.
