Each insulator has advantage and disadvantage of suspension type insulators according to insulator performance, insulator materials and so on.

According to insulator performance, disadvantage of suspension type insulators
◆ As the electric current carrying conductors are suspended from supporting structure by suspension string, the height of the conductor position is always less than the total height of the supporting structure. Therefore, the conductors may be safe from lightening
◆ Suspension insulator string is the every disc of suspension type insulator is costlier than pin and post type insulator
◆ Suspension string requires more height of supporting structure than that for pin or post insulator to maintain same ground clearance of electric current conductor
◆ The amplitude of free swing of conductors is larger in suspension insulator system

Disadvantage of suspension type insulators have many, the above mainly talk about some disadvantages. The technical staff can improve suspension type insulators performance and properties.
