Abstract: A tubular electrical insulation device for a cable is arranged for receiving a plurality of electrical conductors segments by insertion. The insulation device is flexible and includes an inner circumferential electrically conductive layer for establishing an electric contact to the electrical conductors once inserted into the tubular electrical insulation device. A high voltage power cable arrangement includes a plurality of elongated electrical conductor segments arranged to be placed alongside one another and in electrical contact to one another to form an inner electrical conductor of a high voltage power cable, and an elongated tubular electrical insulation device arranged to house and surround the inner electrical conductor. A method for providing a flexible insulated high voltage power cable includes the step of assembling a plurality of elongated electrical conductor segments and an electrical insulation device on site to form the cable.

Abstract: The present invention relates to a material comprising reduced graphene oxide, wherein the degree of reduction of the graphene oxide exhibits a spatial variation so that the material exhibits a gradient in the electric conductivity and/or permittivity. The material can for example be used in an electric device for purposes of field grading and/or dissipation of charges. Examples of electric devices wherein the material is beneficial includes cable accessories, bushings, power cables, microelectronics, switchgear, etc. The invention further relates to a method of producing a material for electrical applications. The method comprises treating different parts of a graphene oxide element differently, so as to achieve a different degree of reduction of the graphene oxide within the element, resulting in a sample having a gradient in the electrical conductivity and/or permittivity. The material could for example be obtained by means of applying a thermal gradient to a graphene oxide element, or by irradiation of a graphene oxide element.
