Abstract
Submersible pump power cable is inserted into a length of tubing. The device comprises an anchoring system attachable to the cable affixed to the tubing inner surface. The anchoring system includes an anchoring sleeve slideable over the cable and insertable into the tubing. Coiling the tubing with the cable and anchoring system inside energizes the sleeve into an anchoring configuration to anchor the cable within the tubing. The anchoring system continues to anchor the cable after uncoiling the tubing and inserting it into a wellbore.
