ABSTRACT:
A cable core, comprising conductors with insulation and carrying a conductive shield layer is protected and shielded by a corrugated metal tube cooperating either with individual, electrically conductive sealing rings, or a conductive helical sealing ribbon with foam filling any gaps. The construction ensures adequate space for thermal expansion of the insulation without undue tensioning of the tube. A method of making the assembly is described and examples for the ribbon and the foam are given.
