NHN绝缘纸是由中间一层聚酰亚胺薄膜及其两面的Nomex1纸(美国杜邦纸)组成、耐热等级为H级（180℃）的柔软复合材料,具有良好的机械性能,如抗拉强度和边缘防撕裂性能以及良好的电气强度.其表面平滑,当生产低压电机使用自动下线机时可确保无故障NHN主要用于高耐热性能电机的槽间,槽盖和相间绝缘,此外也可用作变压器或其他电器的层间绝缘 。 NHN insulating paper is made up of intermediate layer of polyimide film and its two sides Nomex1 paper (the United States dupont paper), heat resistant level for H (180 ℃) of soft composite material, has good mechanical properties, such as tensile strength and edge tear resistance and good electrical strength. Its surface is smooth, when the production of low voltage motor using automatic logoff machine to ensure trouble-free NHN is mainly used for high heat resistance between motor groove, groove insulation cover and alternate with, also can be used as a transformer or other appliances for layer insulation.
