24、tics. Of the few remaining concerns that utilities have todayin using composite insulators, surely the greatest ones are on the aging and life expectancy of these insulators.Initially weathering was considered to be the main factor in limiting life. Although weathering has beenshown to age polymer m
25、aterials, there is a growing body of experience suggesting that composite insulatorlife is more related to design characteristics and/or quality control during their manufacture. With present daypolymer material technology used in good designs and with good quality control during their manufacture,
26、itis entirely feasible to produce composite insulators that will have adequate service life. There are installationswhere polymer insulators have been in service for more than 25 years. This application guide is founded on field experiences, laboratory tests, and on manufacturersrecommendations. It
27、was prepared by a task force of the working group on Non-Ceramic Insulators,Lightning and Insulator Subcommittee, Transmission and Distribution Committee of the IEEE PowerEngineering Society. At the time this guide was approved, G. G. Karady was the chairman of the workinggroup. J. Kuffel served as
28、the chairman of the task force and was instrumental in guiding development of thisguide. The task force members were as follows:G. G. Karady,ChairJ.
