Abstract

The core subassembly of a cable and being comprised of a conductor bundle jacketed in insulation, is provided with a helically wrapped around steel or copper strip on which sits a closed corrugated tube for electrically shielding and sealing the cable interior against moisture. The strip is at least as thick as the expected diameter expansion of the insulation under maximum thermal load.
