Abstract: A dynamic power cable or power cables for submarine applications has at least one extruded fibre reinforced thermoplastic composite core sheath arranged radially around a water barrier sheath.

Abstract: A water barrier (130) for a power cable has a composite layer having a first component, where the first component is a polymer, and at least a second component. The second component is impermeable to water molecules where the second component is selected from fibres having an aspect ratio of 10 or higher and an average length of 1 mm or less, plate-like particles having an aspect ratio of 10 or higher, fibres having an average length of more than 1 mm, fabrics or any combination thereof. The second component is dispersed into the first component, a power cable (100).

Abstract: A dynamic power cable or cables for submarine applications, wherein the dynamic power cable has at least one fibre reinforced thermoplastic composite sheath radially around a water barrier sheath providing reduced buckling of the water barrier sheath. The at least one fibre reinforced thermoplastic composite sheath has wound fibres embedded in a thermoplastic polymer.
