Electric insulation

for oil-filled transformers

Krempel electrical insulation materials for oil transformers Krempel offers the right solution for all insulation applications in oil-filled power and distribution transformers and condensers. We guarantee outstanding processing characteristics, high functional reliability and optimum long-term durability. Impregnation with insulating oil or ester results in the perfect mix dielectric. The reliability of oil transformers is heavily influenced by the quality of the insulation materials used. Both during production and in operation, these insulating materials must be able to reliably withstand a diverse range of mechanical, thermal, electrical, chemical and climatic stresses. Insulation systems for oil transformers are comprised of a number of components: Pressboard in roll and sheet format, blockboard, corrugated board, ladder grids, ladder ducts and PREPREGS. The main insulation materials used in the production of oil transformers are pressboards and components made from pressboard. As a company with almost 100 years of history in the paper and board industry, we are one of the world's leading suppliers of these materials. Our pressboards are manufactured with unique properties depending on the cellulose type, fibre preparation and the configuration of our paper machines.
