我国耐高温非纤维素绝缘纸的现状和发展动向

Status and Development Trends of High-temperature Resistant Non-cellulose Insulating Papers in China

绝缘纸是一种采用造纸工艺生产并广泛应用于变压器、电容器、电机、电线电缆等电气装备中的重要绝缘材料,按其组成可分为纤维素纸和非纤维素纸两大类。随着我国电力工业的持续发展,电机等用电设备逐步向高效小型化方向发展,故对绝缘纸的各项性能尤其是耐高温性能提出了更高的要求,纤维素纸虽然历史悠久,但耐热性不高,已无法满足耐热等级F级以上电气绝缘系统的使用要求,因此耐热性更高的非纤维素纸异军突起。本文简要介绍了我国各类耐高温非纤维素绝缘纸的研发历程、性能特点、主要用途、生产现状及发展动向。

Insulating paper is an important insulating material that produced by papermaking technology and widely used in electrical equipment such as transformers,capacitors,motors,wires and cables.According to its composition,insulating paper can be divided into cellulose paper and non-cellulose paper.With the sustainable development of China’s power industry,motors and other electric equipment are gradually getting more efficient and smaller.Therefore,higher property requirements are put forward to insulating paper,especially high temperature resistant performance.Although cellulose papers have a long history,their heat resistance is not high enough to meet the operating requirements of electrical insulation systems,which need the thermal class of F or above.Non-cellulose papers with higher heat resistance have sprung up.This article briefly introduces the development history,performance characteristics,main uses,production status,and development trends of various high-temperature resistant non-cellulose insulating papers in China.
