Q-P type ball joint hanging plate is a commonly used connecting fitting in transmission line fittings, mainly used for ball and socket connection between insulator strings and tower crossarms, line clamps or other fittings.

Its product usage can be summarized as:

The connection between the insulator string and the tower is in the suspension string and tension string, used to connect the upper end of the insulator string to the cross arm hanging point, and is an important connecting component of the metal fitting string.  

2. The transition connection of the ball and socket structure has a ball head at one end and a hanging plate hole at the other end, which can form a flexible ball and socket connection with the bowl head hanging plate, ball head hanging ring, etc., allowing the metal fitting string to have a certain swinging ability and adapt to changes in the force of the circuit.  

3. Adjust the connection angle of the insulator string. As the ball and socket structure can rotate freely, it can compensate for installation errors and maintain the optimal stress state of the insulator string.  

The standard configuration of suspension and tension strings for transmission lines is widely used in transmission lines with voltage levels such as 110kV, 220kV, and 500kV.  

5. Improve the mechanical reliability of metal fittings with simple structure, high strength, and reliable connection, which can effectively transmit wire tension and load.
