QP, QH & Q type ball head shackle are used for connections with the socket on steel nut subjected to the top section of ball & socket-shaped suspension insulator, avoiding the stress concentration for point contact generated by the connective point. According to different usage conditions, ball head shackles are composed of ring interface type & bolt flat interface.
