The U-shaped hanging ring is a general hardware tool on the line. It is made of hot-dip galvanized round steel and has a wide range of uses. It can be used alone or in two strings. It is often used as an overhead power line and substation to connect insulator strings or steel strands to the tower, and is connected by pins, eye holes and bolts. The shape of the U-shaped hanging ring is very similar to that of the shackle, but the two functions are different. The shackle is a kind of lock for lifting, and the surface treatment is mostly electro-galvanized, while the U-shaped hanging ring is used for hot-dip galvanizing on the power supply line. Power fittings. 1. The U-shaped hanging ring belongs to the connection accessories in the power accessories. The U-shaped hanging rings produced by our company are all round steel forgings, which are used to connect ring accessories to extend the connection size or change the connection direction. When isolating tight lines, a U-shaped hanger can also be used to solve the construction problem of over-traction. 2.On nonlinear towers, it is also possible to install a U-shaped hanger on the insulator strings when the jumper between the two tensile insulator strings is insufficient to withstand the clearance distance to the cross arm due to wind deflection. When dry towers are used for transposition, an extension ring is sometimes installed on the tensile insulator string to meet jumper-to-tower clearance requirements. 3. Connection fittings are used to form a string of hanging insulators and hang them on the tower. The connections between the pendant clips of linear towers and the clips of nonlinear towers and the insulator strings are also assembled by connecting hardware. Others, such as the anchoring of pylons and pylon cable fittings, also use connection fittings.
