Abstract

A cable splice joining insulated conductor ends wherein the conductors are coated with lead, lead-tin alloy or tin, said splice comprising a metallic sleeve member joining the conductor ends, a first layer of adhesive over the sleeve member and any exposed conductor areas, a layer of foil formed of lead or lead-tin alloy covering the first adhesive layer, a second adhesive layer covering said layer of foil and extending over the exposed insulation; a helically-wrapped insulation layer formed of a thermosetting polymer, an over-lapped layer of fabric surrounding the insulation layer, a helically-wrapped heat-shrinkable type layer surrounding the fabric layer, and a heat-shrinkable sleeve surrounding the splice area, and a method for forming said cable splice, for providing cable splices which resist depressurization failure and corrosion of conductors when employed in high pressure gassy oil wells containing corrosive well fluids.
