'绝缘纸NHN介绍
NHN 6650绝缘纸是由中间一层聚酰亚胺薄膜及其两面的Nomex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。
绝缘纸NHN用途
NHN 6650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.
Insulating Material NHN Introduction
NHN 6650is made of two layers of DuPont Nomex paper with one of polyimide film. It has good dielectric properties, high heat resistance and mechanical strength, is suitable for electric motors as slot, phase, turn-to-turn, liner insulation of gradeH.
