Shackle Insulator is currently employed as strain insulators, but it is only used in a small percentage of voltage distribution lines. This can be employed either vertically or horizontally. It is bolted to the pole unless a cross arm is used. This insulator is a low-voltage insulator that is used in distribution networks. Shackle Insulator is another name for this insulator. It can be used in either horizontal or vertical settings. This serves as a barrier between energised elements of an electric circuit, limiting current flow to wires or other conducting routes.
