Abstract: An arrangement for charging of electric vehicles includes a charging connector and a charging cable. The connector includes a connector body with first and second zones, the two zones being separate from each other. The first zone hosts a mating interface with electrical contacts for mating the connector with a corresponding socket of an electric vehicle. The electrical contacts are electrically coupled to the cable. The second zone includes a tube in which the cable is guided from an opening of the tube, which is arranged on that side of the second zone that faces away from the first zone to the electrical contacts, which are located in the first zone, and a handle for grabbing the connector with a human hand, the handle being separate from the tube. The second zone is Y-shaped where the tube is formed by one upper leg and the lower of the Y.

Abstract: A method of building an insulation system around a naked conductor section of a power cable. The insulation system includes an inner semiconducting layer arranged around the conductor, an insulation layer arranged around the inner semiconducting layer, and an outer semiconducting layer arranged around the insulation layer. The method includes: a) placing the naked conductor section in a mold, and b) molding an insulation system around the naked conductor section, wherein the molding of the insulation system involves injecting a first semiconducting compound into a first mold cavity to form an inner semiconducting layer around the naked conductor section, injecting an insulation compound into a second mold cavity to form an insulation layer around the inner semiconducting layer, and injecting a second semiconducting compound into a third mold cavity to form an outer semiconducting layer around the insulation layer.
