In three-layer TRIVOLTHERM® P the non-woven fabric cover on both sides protects the sensitive polyester film against mechanical damage and is highly receptive to impregnation resin. This impregnability significantly improves the thermal dissipation from the winding copper to the iron core with corresponding impregnation. In contrast, when TRIVOLTHERM® P-2 is used, it is necessary to note that the polyester film is not protected against mechanical damage, and impregnants do not adhere as well on the film side. Therefore, when using TRIVOLTHERM® P-2 it is absolutely necessary to pay attention to the orientation of the non-woven fabric and film side in the electrical devices.
Areas of application: Slot insulation, slot closure, stamped parts, layer insulation, intermediate insulation.
