Abstract
A cable splice comprising a metallic sleeve member joining the conductor ends, a layer of adhesive over the sleeve member adjacent insulation and lead sheath, a helically-wrapped insulation layer formed of a thermosetting polymer, an overlapped layer of fabric surrounding the insulation layer, an overlapped layer of lead foil surrounding the fabric layer and extending over the lead sheath a helically-wrapped heat-shrinkable tape layer surrounding the lead foil layer and a heat-shrinkable sleeve surrounding the splice area which resists invasion by corrosive well fluids and consequent corrosive in high pressure gassy wells, and a method for forming said cable splice.
