ABSTRACT:
This invention relates to the mechanical and environmental protection of cable joints, especially in power or other current-carrying cables. Disclosed is a recoverable sleeve which conforms closely to the cable joint, and a liner which bridges the joint and comprises a plurality of elongate elements assembled into a sheet. Flexible means is provided for holding the elements in a side-by-side arrangement and allowing the separation between the elements to vary to allow the liner to conform to the profile of the cable joint. Such flexible means may extend across the element and provide a water vapor barrier. Disclosed also is a method of protecting a cable joint utilizing the sleeve and liner. Where the cables to be jointed have metal armor, screen and/or shielding, the elements may be fabricated from metal or metal alloy and may then provide both armoring and a fault current path across the joint. Use of these more closely conforming joint case assemblies improves heat transfer and reduces the overall size of the joint.
