ABSTRACT:
A lead sheathed power cable especially useful for powering electric submersible pumps in brine wells. The cable is easy to grip and support and resists damage during flexing and chemical attack. The cable comprises at least one power conduit, vulcanized filler material enclosing the power conduit, a lead tube enclosing the filler material, a spacer assembly enclosing the tube, and an outer armor sheath. The armor sheath has a helically grooved inner surface which is interfitted with a conforming helically grooved outer surface on the malleable tube. The outer surface on the tube is helically grooved during initial heating of the cable, which vulcanizes and thermally outwardly expands the filler material and outwardly expands the tube so that the groove on the armor sheath is impressed into the tube. The spacer assembly comprises at least one bedding tape formed of a fabric backing tape with rubber carried thereon and is used to space the outer surface of the tube from the inner surface of the sheath to facilitate flexing of the cable.
