Insulation and Impregnation


   HomeInsulation and Impregnation


The principal components of insulation are pre-fabricated from pressboard sheet. All items subjected to compression in services are preshrunk and the slight recovery in dimensions after preshrink age is compensated for, by providing means of compressing the windings during final drying of the completed transformer .The oil use for impregnation complies with IS 335 and every consignment received at works is tested before entry is permitted into the storage tanks.
