Hey mate ,

Hey mate ,This is your answer ,

Strain type electrical insulators are used when the line is subjected to greater tension such as dead ends, river crossings, sharp curves and when there is a change in the direction of line. The main function of this insulator is to reduce excessive tension on the line.
