Transformer Insulation for Oil cooled Transformers
Oil cooled transformers form the basis and backbone of any transmission and distribution system of power in a country. Oil cooled transformers are the most preferred choice due to their relatively better efficiency and life compared to other types of transformers. Transformer insulation used in such oil-cooled equipment is cellulosic material made from pure unbleached kraft wood pulp. These can be in different forms namely, Transformer Insulating Pressboard and Insulation paper. Given below are different types of Transformer Insulation which are being generally used: Pre-Compressed Press Board components Pre-Compressed Press Board components like spacers, ducts, trapezoidal strips, T- strips, blocks, washers or circles, yoke insulation, phase barrier insulation, cylinders, ladders, etc. These are manufactured by machining of transformers insulating pre-compressed pressboards by process of shearing, punching, moulding, rolling, etc. These components are used in coils and
