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.
Claims15
An insulator housing with a first cylindrical end and a second cylindrical end having a hollow insulator body, which 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, which flange is provided with through bores at the first end thereof for attaching the insulator housing to the external device with at least one bolt arranged at the first end of the flange, characterised in that
- at least one strengthening element provided as clamps or a ring comprising at least two sections is arranged at a second end of the flange,
- said strengthening element being attachable to the external device with bolts through bores in the strengthening element and through the bores arranged in the first end of the flange,
- whereby an easy repair and an improved mechanical strength of an insulator housing which is already in use can be achieved.
