Abstract: A splice assembly and method for splicing electrical cables comprises a sealing layer, a barrier and an open mesh sleeve. The sealing layer is formed of uncured insulation material, surrounds the connector coupling exposed adjacent ends of the cable conductors, and engages the insulation layers of the cables. The barrier surrounds the sealing layer for inhibiting flow of the sealing layer upon heating. The open mesh sleeve surrounds the barrier and has its opposite axial ends rigidly secured to the cables. During curing of the sealing layer, the open mesh sleeve applies substantially uniform and constant pressure in a radially inward direction on the sealing layer to avoid air voids and increase the strength of the splice assembly.
