Abstract
An electrical line for a well pump has elastomeric supports clamped to the exterior of electrical cable for supporting the cable within coiled tubing. The cable supports have an elastomeric member that swells when contacted with a hydrocarbon liquid. Each expansion member is clamped to the cable exterior by retainers located at the ends. The expansion members are spaced apart longitudinally along the cable, and then the cable is inserted into the coiled tubing. Hydrocarbon liquid is pumped through the coiled tubing to cause the expansion members to swell into frictional engagement with the coiled tubing. The retainers direct the swelling laterally into tight contact with the coiled tubing.
