Abstract
Abstract A method of preventing core water from tracking through an electrical cable to a cable splice area is disclosed. The method incorporates a pair of water blocks placed on each side of the cable splice area which blocks the core water thus preventing entry into the cable splice area. The cable blocks are formed by disposing a curable blocking compound around the cable adjacent each side of the cable splice area. The curable compound hardens to a solid form thereby blocking core water penetration.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
109 words
In an elongate electrical cable having an outer jacket and plural insulated conductors extending therethrough, a method of protecting an elongate central extent of said cable where said jacket is opened and said conductors are exposed, said method comprising the steps of: forming an elongate water dam on each side of said central extent, each said elongate water dam spanning a portion of said jacket and a portion of said central extent; disposing an upwardly opening pouch around each said water dam; filling each said pouch with a curable blocking compound; and sealably covering each of said filled dams and a portion of said central extent between said dams.
Claim 2
Dependent Claim
109 words
In an elongate electrical cable having an outer jacket and plural insulated conductors extending therethrough, a method of protecting an elongate central extent of said cable where said jacket is opened and said conductors are exposed, said method comprising the steps of: forming an elongate water dam on each side of said central extent, each said elongate water dam spanning a portion of said jacket and a portion of said central extent; disposing an upwardly opening pouch around each said water dam; filling each said pouch with a curable blocking compound; and sealably covering each of said filled dams and a portion of said central extent between said dams.
Claim 3
Dependent Claim
50 words
A method of claim 1 wherein said forming step includes, for each said side of said central extent: placing a first collar around said jacket adjacent said central extent; and placing a second collar around said conductors adjacent said first collar, said first and said collars defining said water dams.
Claim 4
Dependent Claim
38 words
A method of claim 2 wherein said disposing step includes, for each side of said central extent: disposing said pouch around said first and second collars to thereby define a containment region between said first and said collars.
Claim 5
Dependent Claim
25 words
A method of claim 3 wherein said filling step includes for each side of said central extent: pouring said curable compound into said containment region.
Claim 6
Dependent Claim
18 words
A method of claim 4 further including the step of: compressibly wrapping each of said filled containment regions.
Claim 7
Dependent Claim
36 words
A method of claim 4 further including the steps of: separating said insulated conductors into plural groups at said central extent; and pouring said curable compound into said containment region between said separated groups of conductors.
Claim 8
Dependent Claim
21 words
A method of claim 6 wherein said separating step includes: wrapping said groups of plural insulated conductors with an adhesive-backed tape.
Claim 9
Dependent Claim
14 words
A method of claim 1 wherein said curable blocking compound is a viscous fluid.
Claim 10
Independent Claim
63 words
A method of preventing water tracking within a jacket of an electrical cable from entering into a centrally disposed cable splice, comprising the steps of: disposing a pouch around said cable on each side of said cable splice; and filling each said pouch with a curable blocking compound to form a water block around said cable on each side of said cable splice.
Claim 11
Independent Claim
63 words
A method of preventing water tracking within a jacket of an electrical cable from entering into a centrally disposed cable splice, comprising the steps of: disposing a pouch around said cable on each side of said cable splice; and filling each said pouch with a curable blocking compound to form a water block around said cable on each side of said cable splice.
Claim 12
Dependent Claim
16 words
A method of claim 9 further including the step of: compressibly wrapping each said filled pouch.
Claim 13
Dependent Claim
22 words
A method of claim 9 further including the step of: sealably covering each said filled pouch and said centrally disposed cable splice.
