Abstract
The present invention relates to improved liner constructions, and accordingly provides a cable sleeve liner capable in use of being wrapped around a cable splice and preferably having sufficient rigidity to provide an inner support for a heat-recoverable sleeve to be shrunk thereover, the liner comprising a laminate having at least one layer of fibrous sheet material and a metal layer which is substantially impermeable to moisture vapor and has one of its major surfaces facing away from all fibrous sheet layers which may be present. Preferably the fibrous layer(s) is or are arranged between the metal layer and a microperforated first layer of flexible polymeric film material which is permeable to gases or vapors generated within the laminate during recovery of the sleeve.
Claims9
A cable splice case comprising a cable sleeve liner wrapped around a cable splice and a sleeve surrounding the wrapped liner, said cable sleeve liner comprising a laminate having at least one layer of a fibrous non-woven cellulosic sheet material between a metal layer which is substantially impermeable to moisture vapour, said metal layer having one of its major surfaces facing away from all fibrous sheet layers present in the liner, and a microperforated first layer of flexible polyester film material which is vapour-permeable to permit escape of gases or vapours generated within the laminate during recovery of the sleeve.
