Crinkled Insulating Paper
产品简介：
电工皱纹绝缘纸是由100%纯进口纸桨生产的绝缘纸，经特殊起皱工艺加工而成，其特点是油溶性能非常好，广泛应用于油浸式变压器、互感器、电抗器等绕包部位绝缘、引线部位绝缘的包裹，从而提高了产品绝缘结构的电气性能和机械性能。
Introduction:
Electrical insulating paper, purely made from imported pulp through special wrinkling process, is characterized by excellent oil-soluble performance, and widely applied in the insulation of lapped parts of oil-immersed transformers, mutual inductors and reactors, and the insulating wrap of down-lead parts. It helps to improve the electrical and mechanical performance of products’insulation structure.
