UB hanging plate is the most widely used joint tower fittings in the world, and some products with improved structure have new names, such as trunnion hanging plate and so on. Their common features are: the upper end of the hanging plate (side of the cross arm) is connected with the cross arm by a long rod bolt, and the bolt bears the force state of the double shear plane, and the lower end of the hanging plate (side of the insulator string) is usually connected in a groove shape. Including single plate type and double plate type. The upper end forms the front and rear rotation axes, the lower part forms the left and right rotation axes, and the two axes form a 90-degree rotation angle. UB type hanging board has high strength and reliable quality. 1. The processing size is accurate, higher than the rated mechanical load. 2. Adopt advanced galvanizing process to ensure uniform, smooth zinc layer and strong corrosion resistance. 3. Easy to install and easy to maintain. 4. Standard design, good versatility; 5. Forged high-quality steel, dense material, higher mechanical properties; 6. Use pins or bolts to connect with other products
