Power transformer bushing 72.5 - 1 200 kV | OTA

distribution

Type OTA bushings are designed according to the latest IEC 60137 issue, various international standards and ANSI standards for transformer applications. The bushings are available in a range from 72.5-1,200kV in the most typical ratings. The features include optimized construction for the purpose of meeting the latest classification of Group II for cantilevers' withstand load. It is possible to install the bushings up to 30° from a vertical position. The proven reliability record regarding the OIP condenser bushings ensures a very low partial discharge level with transformer tests. An added benefit is the service operation that is partially free from discharge. The design of these units allow for the bearings to meet highly demanding pollution conditions as well as heaving wetting conditions. A conical porcelain shell houses the transformer-end insulation.
