COILED TUBING SUPPORTED ELECTRICAL CABLE HAVING INDENTATIONS

摘要

An electrical line for installation in a well for transmitting power to a we ll pump includes a string of coiled tubing. An electrical cable having insulate d electrical conductors embedded within an elastomeric jacket extends longitudinally through the interior passage of the tubing. Retainers are mounted to the electrical cable and spaced longitudinally apart from each other. An indentation is integrally formed in the tubing adjacent each of th e retainers. Each indentation protrudes into the interior passage of the tubin g and creates a ledge which is contacted by one of the retainers when the electrical line is installed in the well. The indentations and retainers transfer weight of the electrical cable to the tubing. Weld material is fill ed into the depression on the surface created by each indentation.
