Water Diffusion Barrier – A Novel Design for High Voltage Subsea Cables

High voltage subsea cables are normally sheathed with a metallic water barrier at voltage levels above 36 kV as recommended by the standards (IEC 60840). The main concern with water ingress in power cables is the risk of water tree formation. Water tree growth will reduce the lifetime of power cables. For dynamic cable designs there are today few reliable alternatives to prevent the water ingress. Here a novel electrical semi-conductive water barrier is presented, based on a multilayer polymer sheath design where the arrangement of layers is based on numerical simulations using measured water transport data.
