Abstract

An electrical cable assembly (10) comprising a cable core (12) and filler layer (16) encased in longitudinally welded reeled tubing (23) so as to restrict relative axial and longitudinal motion between the cable core (12) and reeled tubing (23). Small-diameter tubing (24) is optionally provided as part of the cable core (12) to facilitate the delivery of fluids such as lubricants and corrosion inhibitors to downhole equipment. A method is disclosed for deploying electrical cables in deep wells through use of the subject apparatus.
