Title: Electric cables having a metal foil-plastics moisture
IPC: H01B7/282
Filed: 1969-08-11
Abstract: A method of forming a moisture-proof barrier in a cable consists in forming a layer of metal foil and bonding this layer to an outer sheath of a plastics material. The metal foil layer is formed from strip material by longitudinally folding the strip about the cable core or by helically wrapping the strip around the core, either system producing an overlapping joint. The plastics material sheath is applied over the foil and the foil is heated by e.g. the application of an rf. field, to bond the sheath to the foil while the sheath is still hot from the application process. The metal foil may e.g. be aluminium and the plastics material a thermoplastic or a thermosetting material.
