Quick Detail: 

36kv 66kv 132kv suspension glass insulator string for pole lines has become popular in transmission line and

distribution line system. To attach the conductors to angle,strain,section or dead-end supoorts,multiple insulator

sets are used,whose insulator strings should be directly connected to the crossarm by means of hinges or shackles.
