The conductive body is encapsulated within the insulating body and defines a conductive network therein to regulate an electric field within an underlying insulator from current flowing through a conductor along the regulation axis. Cables and methods of regulating electric field within cables are also described.

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.

Devices, systems and methods to prevent damage to power and communication conductors located in cold occurring regions, with an elongated cylindrical tubular assembly of closed cell foam within a braided/woven layer that can be sealed to provide longitudinal strength and a snag resistant durable and flexible outer coating. The assembly along with communication and power lines is pulled through new power and communication ducts and conduits and in retrofitting existing power and communication ducts, so that the assembly reduces the volume spacing in the ducts/conduits that can be damaged by water intrusion which expands during freeze conditions.
