Abstract
A cable splice comprising a metallic sleeve member joining the conductor ends, a layer of adhesive over the sleeve member and adjacent insulation, a helically-wrapped insulation layer formed of a thermosetting polymer, an overlapped layer of fabric surrounding the insulation layer, a helically-wrapped heat-shrinkable tape layer surrounding the fabric layer and a heat-shrinkable sleeve surrounding the splice area which resists depressurization failure when employed in high pressure gassy oil wells, and a method for forming said cable splice.
Claims7
A cable splice comprising a metallic sleeve member extending over conductor end portions and frictionally engaging the conductor end portions;
- a layer of adhesive covering said sleeve member and extending over the exposed cable insulation;
- an insulation layer of uncured thermosetting elastomeric polymer tape surrounding the layer of adhesive in a helical wrap;
- an overlapped layer of fabric surrounding said insulation layer;
- a helically-wrapped layer of heat-shrinkable polymeric material tape surrounding said layer of fabric, and
- a sleeve of heat shrinkable polymeric material surrounding the layer of heat shrinkable polymeric material tape.
A method for forming a cable splice comprising the steps of
- joining the exposed conductor ends with sleeve means frictionally engaging said conductor ends;
- coating the sleeve means, the exposed conductor ends and the exposed insulation with a liquid adhesive;
- applying an insulation layer of uncured thermosetting elastomeric polymer tape over the adhesive coating in a helical wrap;
- applying an overlapping layer of fabric to surround said insulation layer;
- applying a layer of heat-shrinkable polymeric material tape in a helical wrap;
- and
- positioning a sleeve of heat-shrinkable polymeric material to surround the layer of heat-shrinkable tape.
