Abstract

Conductors are placed in insulator which acts as a spacer/centralizer for the conductors, which are in turn mounted within tubing. The void spaces between the insulator and the tubing inside wall can be filled with a sealing material. Alternatively, the voids around the substantially centralized conduc-tors can be used as flow channels for the transmission of fluid pressure to a remote location, such as downhole. The conductors are protected because they are kept away from the tubing wall and can be further protected by the addition of the sealing material.
