1. Means for enclosing a portion of at least one cable, comprising(a) expandable first means adapted for surrounding at least the portion of the cable and for being sealed to the cable, thereby forming containment means adapted for receiving therein, through encapsulant-introduction means, a quantity of liquid encapsulant of a type whose viscosity increases with time until the encapsulant is no longer a liquid at room temperature;

  • and(b) substantially rigid outer enclosure means adapted for surrounding the containment means characterized in that(c) the containment means are adapted for having the liquid encapsulant therein pressurized to a first pressure that is substantially greater than ambient pressure, and for maintaining the liquid encapsulant therein under a pressure above embient pressure for a time such that at least part of the encapsulant is no longer a liquid at room temperature;

    (d) the outer enclosure means are adapted for substantially restraining expansion of the containment means with the pressurized liquid encapsulant therein; and

    (e) the encapsulant-introduction means are of a type that permits further introduction of liquid encapsulant into the containment means after introduction and pressurization of the quantity of liquid encapsulant.
