Abstract
ESP power cable is inserted into a length of tubing disposed in a wellbore. The device comprises a support attachable to the cable that is in frictional sliding contact with the tubing inner surface. The frictional sliding contact between the support and the tubing reduces axial stress in the cable. Support devices are added at intervals on the cable length, thereby distributing the cable axial stress along the cable.
