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 surge arrester including a stack of a plurality of cylindrical varistor blocks that are arranged one after the other in the axial direction of the varistor blocks between an upper end electrode and a lower end electrode. Arranged around the stack are clamping members of an insulating material including at least three loops of continuously wound fiber that connect the upper end electrode to the lower end electrode as well as a bursting-protective bandage in the form of a plurality of rings wound of fiber, and a surrounding, electrically insulating, outer casing of rubber or other polymeric material. The loops are wound from glass fiber and exhibit an asymmetrical cross section.
