Power cable with plastic insulation and an outer conducting layer
First Claim
1. In a power cable including a central conductor, an extruded inner conducting layer surrounding said conductor, an inner layer of extruded insulation surrounding said inner conducting layer, an extruded outer conducting layer surrounding said insulating layer, a metal shield surrounding said outer conducting layer, and an outer insulating layer surrounding said metal shield, an improved construction permitting said outer insulating layer, metal shield and outer conducting layer to be peeled away from said inner insulating layer without damage to said outer conducting layer, comprising an intermediate insulating layer having a mechanical peel strength lower than the mechanical peel strength of the outer conducting layer and of said inner insulating layer, said intermediate insulating layer interposed between said inner insulating layer and said extruded outer conducting layer.

Abstract
In a power cable including a central conductor, an extruded inner conductor surrounding the conductor, an inner layer of extruded insulation surrounding the inner conducting layer, an extruded outer conducting layer surrounding the extruded insulation, a metal shield surrounding the outer conducting layer and an outer insulating sheath surrounding the metal shield, an intermediate insulating layer having a mechanical peel strength lower than that of the outer conducting layer and of the inner insulating layer is interposed between the inner insulating layer and the outer conducting layer to permit the outer insulating layer, metal shield and outer conducting layer to be easily peeled away from the inner insulating layer without damage to the outer conducting layer and without leaving a conducting residue on the inner insulating layer.
