Abstract: An electrical insulator including: a first connector of an electrically conducting material; a second connector of an electrically conducting material; and an electrically insulating material being arranged between the first connector and the second connector, insulating the connectors from each other; wherein a part of the first connector extends past a part of the second connector, partly enveloping part of the second connector. The invention also relates to a surge arrester arrangement, to a use of an electrical insulator for insulating a surge arrester, and to a method for production of such an electrical insulator.

Abstract: An insulator housing suitable for electrical products for high voltage, for example, surge arresters, breakers or bushings. The insulator housing includes a first cylindrical end and a second cylindrical end having a hollow insulator body. The first end and/or second end is provided with a cylindrical flange for attaching the insulator housing to an external device at a first end of the flange. A strengthening element is arranged at a second end of the flange.

Abstract: A method for the preparation of very accurate measuring surfaces on measuring elements such as gauge blocks, surface plates, and the like. In one embodiment of the inventive method, the measuring surface is prelapped to a level of two to five microns below the desired final level. Thereafter, the surface is sputter coated with a hard ceramic or cermet layer with a thickness of three to ten microns, and finally the surface is lapped until the final desired level is reached. The invention also comprehends measuring elements made according to the novel method.
