The precursor products used are what make the exceptional properties of TRIVOLTHERM® N possible. The adhesive used is especially significant. In developing it, we were able to build on our decades of lamination know-how and produce an adhesive that combines the individual components with each other in an optimal way. The excellent chemical and thermal properties of the NOMEX® aramide paper complement the good electrical and mechanical values of the polyester film ideally. Aramide papers are characterised by exceptional resistance to chemicals, solvents and high temperatures. Thus the aramide paper cover layers protect the polyester film even at high temperatures against harmful effects due to oxidation and hydrolysis and mechanical damage. Furthermore, despite the smooth surface of the calendered aramide paper, impregnation resins bind to TRIVOLTHERM® N very well.
Areas of application: Slot insulation, slot closure, stamped parts, intermediate insulation, dry-type transformers.
