Abstract

A method of forming a core of cables, which comprises extruding a layer of rubber or plastic insulating material on a moving conductor, which may or may not have a conductive shield applied thereon, to form the core dielectric; applying an intermediate layer of rubber or plastic insulating material to the outer surface of the core dielectric such that the intermediate layer adheres to, or can subsequently adhere to, the core dielectric; and applying a layer of conductive or semiconductor material of rubber or plastic to the outer surface of the intermediate layer, in such a way that the dielectric shield thus formed adheres to, or can be subsequently adhered to, the intermediate layer. bond strengths between the intermediate layer and the core dielectric, and between the intermediate layer and the dielectric screen, substantially greater than the cohesion resistance of the intermediate layer, throughout the entire layer, or at least in one area circumferentially continuous of the layer, and the intermediate layer in the final product having a less cohesion resistance than the cohesion resistances of the inner dielectric and the dielectric screen.
