Crinkled Insulating Paper
產(chǎn)品簡介：
電工皺紋絕緣紙是由100%純進(jìn)口紙槳生產(chǎn)的絕緣紙，經(jīng)特殊起皺工藝加工而成，其特點(diǎn)是油溶性能非常好，廣泛應(yīng)用于油浸式變壓器、互感器、電抗器等繞包部位絕緣、引線部位絕緣的包裹，從而提高了產(chǎn)品絕緣結(jié)構(gòu)的電氣性能和機(jī)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.
