Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
104 words
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 and exposed lead sheath; an insulation layer of uncured thermosetting elastomeric polymer tape surrounding said layer of adhesive in a helical wrap; an overlapped layer of fabric surrounding said insulation layer; an overlapped layer of foil surrounding said layer of fabric; a helically-wrapped layer of heat-shrinkable polymeric material tape surrounding said layer of foil; and a sleeve of heat-shrinkable polymeric material surrounding the layer of heat-shrinkable polymeric material tape.
Claim 2
Dependent Claim
104 words
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 and exposed lead sheath; an insulation layer of uncured thermosetting elastomeric polymer tape surrounding said layer of adhesive in a helical wrap; an overlapped layer of fabric surrounding said insulation layer; an overlapped layer of foil surrounding said layer of fabric; a helically-wrapped layer of heat-shrinkable polymeric material tape surrounding said layer of foil; and a sleeve of heat-shrinkable polymeric material surrounding the layer of heat-shrinkable polymeric material tape.
Claim 3
Dependent Claim
21 words
The cable splice of claim 1 wherein the lead foil layer end portions and lap area are coated with an adhesive.
Claim 4
Dependent Claim
18 words
The cable splice of claim 1 wherein the thermosetting elastomeric polymer tape is cured by a thermal post-treatment.
Claim 5
Independent Claim
112 words
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 the exposed insulation and the exposed lead sheath 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 an overlapping layer of lead foil to surround said fabric 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.
Claim 6
Independent Claim
112 words
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 the exposed insulation and the exposed lead sheath 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 an overlapping layer of lead foil to surround said fabric 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.
Claim 7
Dependent Claim
22 words
The method of claim 4 wherein the layer of lead foil is coated in the end and overlap areas with an adhesive.
Claim 8
Dependent Claim
18 words
The method of claim 4 further comprising the step of thermally-treating the splice to shrink the heat-shrinkable materials.
Claim 9
Dependent Claim
19 words
The method of claim 6 further comprising the step of thermally-treating the splice to cure the thermosetting elastomeric polymer.
