Abstract
A string of coiled tubing for an electrical submersible well pump has insulated power conductors encased in an elastomeric jacket within the coiled tubing. A textured interface between the jacket and the inner side wall of the coiled tubing enhances frictional engagement between the jacket and the coiled tubing. The textured interface may be formed on the inner side wall of the coiled tubing and consist of a roughened or knurled surface. A tape may be wrapped helically around the jacket, the tape having an outer side with a textured surface in contact with the inner side wall of the coiled tubing. The textured interface may extend continuously for the length of the coiled tubing.
