The bowl head hanging plate series is a key connecting fitting used in transmission line fittings to match with ball head structures. Its main function is to connect insulator strings, wire clamps, and other fittings, forming a rotatable ball and socket connection.

Its product usage can be summarized as:

1. The bowl mouth of the ball joint hanging plate of the ball joint hanging ring/ball joint insulator is matched with the ball joint structure to form a freely rotatable connection, so that the insulator string can adapt to changes in line stress and installation errors.  

2. The connection between the insulator string and the wire clamp or hardware string is used in the suspension string or tension string to connect the lower end of the insulator string with the suspension wire clamp, tension wire clamp or other hardware.  

3. Adjust the swing angle of the insulator string. The ball and socket structure can rotate, allowing the insulator string to swing freely under wind and ice loads, avoiding additional stress.  

4. Standard fittings for transmission lines are widely used in transmission lines with voltage levels such as 10kV, 35kV, 110kV, 220kV, and 500kV.  

5. Improve the flexibility and reliability of metal fittings. Compact structure, high strength, and flexible rotation are indispensable connecting fittings in transmission lines.
