Abstract

A flexible wrap (10) for enclosing a cable splice (20) without external heating includes a gel layer (1) and a support layer (2). The wrap has sufficient flexibility to be manually gathered into wrinkles around the smaller parts of the cable-to-splice transition with the gel sealing the resulting enclosure. The support layer (2), which is preferably made of low density polyethylene, provides mechanical strength and facilitates the application of the wrap (10). A vapour barrier layer (3), preferably made of aluminium, may be applied on the support layer (2). A protective layer (4) may be applied on the vapour barrier layer (3). An adhesion-reducing substance (6) may be applied on at least part of the side of the gel layer (1) facing away from the support layer (2) to allow adjustment of the wrap (10) when applied on the cable splice (20). Elastic or rubber tape (11) maybe wound around the applied wrap (10) to compress the gel. A re-enterable closure having a long sealing length may be obtained.
