In a wrapping unit for sealing and protection of cable splices and of the type which comprises an outer shrink- on jacket 5, preferably of heat-restituted material, which surrounds a cable and a thermoplastic support layer 7 which lies inside the outer jacket 5 and surrounds the cable, [it] comprises a heat insulating layer 6, preferably of foam material, between the support layer 7 and the outer jacket 5. This prevents thermal deformation of the thermoplastic support layer 7 during the heat shrinking of the outer jacket 5 or other heat treatment. <IMAGE> |
