SynTherm® – Insulating Materials SynTherm® NPN/130 411
SynTherm® NPN/130 411 is a flexible 3-ply insulation.
It consists of a polyester film with an uncalandered Nomex® layer type 411 on both sides.
The proven electrical and mechanical properties of the polyester film and the excellent thermal resistance of the outer Nomex® layers result in a high performance insulating material. SynTherm® NPN/130 411 is easy to form and, therefore, displays good processing characteristics as phase insulation. The ability of the uncalandered Nomex® layers to absorb impregnants results in excellent bonding between all winding components. SynTherm® NPN/130 411 is characterised by its high thermal and chemical resistance.
Application
SynTherm® NPN/130 411 is especially used as phase insulation for electric motors. In special cases SynTherm® NPN/130 411 can be used as core and interlayer insulation for transformers.
