Abstract: A self-disinfecting robot including an exterior surface. The robot includes at least one light emitting component arranged to illuminate at least a part of the exterior surface with disinfecting light from inside the robot. By projecting disinfecting light from the inside of the robot, one may provide a constant and complete disinfection of the exterior surface (or selected parts of it) e.g. during service or operation, including when the robot is moving around. The solution also allows disinfection of e.g. crevices that would also be difficult to disinfect from the outside. Furthermore, the robot may also, to some extent, treat the surrounding environment and in particular the airborne particles around the robot. The disclosure also relates to a corresponding method for disinfecting a robot, to a computer program and to a computer program product.

Abstract: The present invention relates to an electrical transformer comprising an electrical insulator and a winding of an electrical conductor around a core, said insulator being formed of an essentially non-porous composite material comprising a resin matrix and up to 85% by weight of insulating fibres surrounded by the resin matrix, the composite material having a maximum moisture content of less than 0.5% by weight at 23° C. and 50% relative humidity.

Abstract: An insulation system for an electrical power transformer that includes at least a non-cellulose based axial spacer. The axial spacer may include a pair of spacer arms that extend from a base wall of the axial spacer. Additionally, the spacer arms and the base wall may generally define a hollow inner region of the axial spacer, thereby reducing the volume of the axial spacer. According to certain embodiments, the spacer may include lips that are adapted to lockingly engage a radial spacer. Additionally, at least a portion of the axial spacer and the radial spacer may be constructed from a thermoplastic and/or a thermoset plastic. Further, according to certain embodiments, another portion of the axial spacer, such as, for example, the lips, may be formed from a flexible thermoplastic elastomer or a thermoset elastomer so as to provide the axial spacer with a combination of both flexibility and stiffness.
