Recoverable closure assembly

摘要

An assembly for sealing and protection of cable splices comprising a recoverable, preferably heat-recoverable outer sleeve 5 surrounding a cable or other body 1; a thermoplastic support layer 7 surrounding the body 1 and within the sleeve 5; and a heat barrier layer, preferably foamed, between the support 7 and the sleeve 5, to prevent thermal deformation of the support 7 during heat recovery of the sleeve or during other heat treatment 5.
