Abstract: A laminate structure having a metal foil having a lower and an upper surface area, a first layer of a thermoplastic polymer laid onto and covering the lower surface of the layer of metal foil except for a longitudinal uncovered surface area of the layer of metal foil, and a second layer of thermoplastic polymer laid onto and covering the upper surface of the layer of metal foil except for a longitudinal uncovered surface area of the layer of metal foil, and wherein the laminate structure is wrapped around the cable core such that the first uncovered surface area of the metal foil faces the cable core and the second uncovered surface area of the metal foil faces away from the laminate structure, and the laminate structure is thermally joined by a heat treatment.

Abstract: A water barrier for encapsulating a cable core has a layer of metal foil having a thickness of t1, and a single layer of a polyethylene-based polymer having a thickness of t2. The ratio t2: t1 is at least seven, and the single layer of a polyethylene-based polymer has been deposited onto the metal foil by extrusion at an extrusion temperature of at least 150° C., with the metal foil preheated to a temperature of at least 130° C.

Abstract: A reinforced water barrier over a joint between power cables is suited for subsea cables having different water barrier/sheathing designs. The reinforced water barrier has an intermediate water barrier made of lead or a lead alloy which stretches over the joint and is attached to the underlaying water barriers of the joined cables, and which is reinforced by being coated with a layer of polyethylene based adhesive followed by a layer of polymeric outer sheathing. The adhesive layer and the layer of polymeric outer sheathing are thermally set by a heat treatment.
