Abstract
A lead-free water barrier suited for dynamical submarine high voltage power cables has a water barrier including a laminate structure. The laminate structure has a metal foil having a lower and an upper surface area. A first layer of a thermoplastic semiconducting polymer is laid onto the first adhesive layer, and a second layer of a thermoplastic semiconducting polymer is laid onto the second adhesive layer. The laminate structure is thermally joined by a heat treatment.
Claims13
A water barrier encapsulating a cable core,
- wherein the water barrier comprises:
