ABSTRACT:
A method and apparatus for enclosing a splice joining at least first and second cable segments prevents water from entering the splice. The apparatus includes a flexible reservoir sealingly attachable to a sealing surface of an end plate assembly. The end plate assembly is sealingly attachable to the cable segments. The pressurized splice closure sections sealingly engage one another and the end plates. The method includes forming a reservoir about the splice, sealing the reservoir to the first and second conductor segments or to the end plates, forming an opening in the reservoir, pouring a curable encapsulant into the reservoir, working the encapsulant into intersitices between the conductors in the cable segments, sealing the reservoir, enclosing the reservoir in a splice closure and pressurizing the splice closure. This method combines a curable encapsulant such as a two-part polyurethane with a pressurized closure such as a 2-type, gas pressurized closure.
