A comprehensive technical and economic comparison of the insulator

    Synthetic insulators, glass insulators, porcelain insulators comprehensive technical and economic comparison of Guangzhou Power Authority Lozen sea, a Chen Xiong, Xiao Dinghui, Yuanyou Liang Abstract synthetic insulators, glass insulators, and the performance and operation of porcelain insulators extensive comparison, discusses the use synthetic insulators and glass insulators should be noted that the problem should be obtained when using the new high-voltage line insulator glass insulator and synthetic conclusions. Keywords synthetic insulators, glass insulators, porcelain insulators, line operation, technology is relatively l lead officer present, high-voltage overhead line insulators used are porcelain insulators, glass insulators and synthetic insulators three categories. Porcelain insulators have many years of operating experience, reliable operation, but has zero detect problems and poor antifouling properties; glass insulation in more than 30 years of operational experience, particularly in the 1980s, extensive use of glass insulators on the line to good effect, run easy maintenance, welcomed by users; in the early 1990s, synthetic insulators to be more widely used in Guangzhou power grid since 1991 the use of synthetic insulators, operating experience shows that it has a series of porcelain and glass insulators incomparable advantages, such as high strength, light weight, easy to install, good stain resistance, similar to the advantages of maintenance-free and so is not subject to zero. First, the use of synthetic insulators effectively curb pollution flashover, 1990 Love Beida area pollution flashover, the composite insulator flashover no string, Guangzhou Power Supply Bureau after several heavy duty line hang synthetic insulators, pollution flashover did not occur for several years. In addition, the use of synthetic insulators significantly reducing maintenance workload
