An electrical cable or electrical cable accessory includes at least one semiconductor layer, and at least one electrically insulating layer, at least partially in direct contact with the semiconductor layer. The electrically insulating layer is obtained from an insulating polymer composition having a thermoplastic polymer material, and the semiconductor layer is at least partially crosslinked.

Electrical cable or electrical cable accessory

Power cables are provided having a joint with a metallic water barrier and, in particular, metallic water barrier materials for cable joints for use in high voltage cables for both land and submarine applications.

Power cable with a cable joint water barrier made of tin or tin alloy

An insulation system for jointing of high voltage conductors has an inner layer made of a crosslinked first polymeric semiconducting material, an intermediate insulating layer made of a thermoplastic polymeric insulating material, and an outer layer made of a second polymeric semiconducting material. The insulation system is adapted for surrounding the electric conductor joint.

Joint for electrical cables and method for jointing

A water barrier for encapsulating a cable core has a layer of metal foil having a thickness of t, and a single layer of a polyethylene-based polymer having a thickness of t. The ratio t: tis 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.

Low resistance polyethylene sheath with combined adhesive and mechanical properties

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.
