Abstract:
1. A method of assembling power cable for an electrical submersible pumping (ESP) system with downwardly oriented borehole tubing, the method comprising: suspending a length of power cable from a hanging point into the downwardly oriented borehole tubing, wherein the length of power cable forms an axial stress in the power cable proximate to the hanging point; providing a support having an annular body with a portion with a smaller radius and a portion with a larger radius and a resilient member slidably set around the body; attaching the support to the power cable; and lowering the power cable with attached support into the borehole tubing with the support oriented so that the portion of the body with the larger radius enters the tubing before the smaller radius portion and the resilient member is in sliding frictional contact with an inner surface of the tubing.
