ABSTRACT:
A coil tubing electrical power cable system for use with a submersible pump in oil well and/or water well pumping applications. The cable includes a plurality of insulated electrical conductors enclosed in a low tensile strength corrosion-resistant metal tubing. The twist factor or lay length of the conductors is approximately eight to fourteen times the diameter of the insulated conductors in order to overcome the tensile loads and elevated temperatures which cause z-kinking. In addition, the electrical cable may include one or more hydraulic tubes.
