Abstract
A heat-shrink tube for an electrical power cable comprises a sleeve having an insulating inner layer, a conductive outer layer and a thermoplastic mid-layer located between the inner and outer layers. The mid-layer is recovered by the application of heat thereto. The insulating inner layer is preferably comprised of an elastomeric material and the thermoplastic mid-layer is rigid and acts to retain the inner layer in a radially expanded state prior to its recovery.
