As insulating and supporting conductor in HV transmission & distribution line, post insulators are divided into line post porcelain insulator, cross arm porcelain insulator and long rod suspension insulator etc. They have the characteristics of no puncture, high mechanical strength, excellent insulation and anti-pollution. This kind of insulator is safe and reliable in operation, simple in maintenance, long life in running and lower in price.
