Solid Core Line Post Insulators can be used as support for conductors on cross-arms of transmission and distribution line poles. These Solid Core Line Post Insulators are recommended for polluted zones and areas prone to vandal damages. Even if the insulator shed is damaged, there will be little decrease in flashover voltage and power supply will not be disturbed. The damaged insulator can be left in service and replaced conveniently. No change in cross arm is necessary, if pin type insulators are replaced by line post insulators during maintenance.
