Abstract: A high-voltage DC cable joint comprising a multi-wall layered construction having individual concentrically arranged layers. The joint comprises, from inside to outside, an inner conductive rubber layer (1), a field grading rubber layer (2) made from a predetermined tailored formulation, an insulating rubber layer (3) and an outer conductive rubber layer (4). The field grading rubber layer separates and interconnects the conductive rubber layers, and wherein the rubber layers are cross-linked by a by-product-free manufacturing method. The cable joint is preferably made from platinum cured rubbers by moulding process steps. In a preferred embodiment the cable joint is made by injection moulding.

Abstract: An insulation of wound conductor for an electrical machine is proposed. The conductor (201) includes m conductor strands wound as Roebel bar out of an electrically conductive, an insulation layer (203) being at least partially provided around the conductor (201).
