ABSTRACT:
A forced encapsulation system and method that can be advantageously used to encapsulate cable splices e.g., multiconductor communications cables. Containment means are formed around a substrate comprising part of at least one cable, and secured to the cable, thereby forming an enclosure into which liquid encapsulant can be introduced under pressure and in which the encapsulant can be maintained at pressure above ambient pressure. In a preferred embodiment, the containment means comprise a containment bag formed in situ from an elastomer sheet and sealed to the cable sheaths, with a reinforcing outer enclosure surrounding the containment bag. Introducing the liquid encapsulant under pressure leads to thorough penetration of the encapsulant into the splice work and cable ends and to intimate contact between the cured encapsulant and the surfaces within the enclosure, including surfaces with which the encapsulant does not form an adhesive bond, resulting in improved gasketing around conductors, thereby reducing the possibility of water-caused splice damage.
