一、前言电工绝缘问题是关系电工产品质量和发展前途的重要问题。近年来,我国高等院校、科研单位和工厂都对电工绝缘作了不少的研究工作,并取得了较大的进展。有关学会也曾多次进行了电工绝缘方面的学术交流活动。1985年6月,中国电工技术学会、美国电工电子工程学会(IEEE)和西安交通大学在西安联合举办的首届《国际电介质材料性能 I. Introduction Electrical insulation is an important issue concerning the quality and development of electrical products. In recent years, many colleges and universities, research institutes and factories in our country have done a lot of research on electrical insulation and have made great progress. The Society has also conducted several academic exchange activities in the field of electrical insulation. June 1985, the China Institute of Electrotechnical Technology, the United States Institute of Electrical Engineering and Electronics (IEEE) and Xi'an Jiaotong University in Xi'an jointly organized the first "international dielectric material properties
