Models: U-0770, U-1085, U-1290, U-1695, U-21100, U-25110, U-32115, U-42140, U-50150.
Material: Typically made of hot-dip galvanized round steel forging, offering excellent corrosion resistance and adaptability to harsh outdoor operating environments.
Structure: Similar in appearance to a shackle, it is U-shaped and connects using pins, eyelets, and bolts. It can be used alone or in pairs.
Application: Commonly used to connect insulator strings or stranded wire to pole towers in overhead power lines and substations. It can also be used as a tension string or jumper tower hardware on tension towers, and is occasionally used on straight-line towers.
U-shaped hanging ring is a commonly used connection fitting in power fittings. It is named after its "U" shape. There are connection holes at both ends, which can be inserted with bolts, pins or other connectors. It is used to connect the insulator string with the pole tower, cross arm or other fittings. It has the characteristics of simple structure, convenient connection and clear force. High-quality U-shaped hanging ring is made of hot-dip galvanized steel, which has strong anti-corrosion performance and is suitable for outdoor power environment. When in use, it is usually used in combination with other fittings, especially insulator string, hanging plate, wire clamp, right-angle hanging ring, to play different roles.
As a key connection component in the fields of power, construction, and industrial equipment, the U-shaped hanging ring has many advantages:
High bearing capacity
high structural strength, nominal load coverage of 70-160kN, can withstand dynamic loads such as conductor tension, wind vibration and icing, and the U-shaped bending structure makes the tension evenly distributed to avoid stress concentration and fracture;
Corrosion resistance
The surface hot-dip galvanized layer thickness is ≥50μm, which can effectively resist rain, salt spray and industrial corrosive media, and extend the outdoor service life to more than 15 years. Stainless steel is selected in coastal or chemical areas, which will not be corroded by salt spray;
Strong temperature resistance
Applicable temperature The range is -40℃ to +120℃, which can adapt to the operation of power lines under extreme climatic conditions;
Universal connection interface
The U-shaped open end is compatible with M16-M24 standard bolts, suitable for various power fittings such as insulator strings and tension clamps, and supports quick disassembly and assembly;
Easy installation
No special tools are required, and construction workers can complete the fixation through pins and nuts, reducing the time of high-altitude operations;
Safe and reliable
The aperture tolerance is controlled within ±0.5mm to ensure close fit with the bolts to avoid the risk of slippage, and the bending angle is strictly maintained at 90° to ensure the force balance after multiple hanging rings are connected in series.
It is precisely because of these characteristics of the U-shaped hanging ring that it is widely used in high-voltage transmission lines, coastal chemical environments, and temporary fixation of construction, playing a very important role.
Common models of U-shaped hanging rings are U-7, U-10, U-12, U-16, and U-21. The larger the model number, the higher the nominal breaking load, and the ring body diameter, opening width, and total length are also increased accordingly to adapt to higher voltage levels, greater conductor tension, or more complex stress environments. Selection principles:
Load matching
Calculate the actual load based on the tension, spacing, icing conditions, etc. of the line conductor or ground wire, and select a model with a nominal breaking load higher than the actual load;
Voltage level adaptation
Small models can be selected for low voltage levels, and U-16 and above models must be selected for high or ultra-high voltage lines;
Connection size matching
Ensure that the bolt hole diameter of the U-shaped hanging ring is consistent with the specifications of the connector.
The U-shaped hanging ring and UB-shaped plate differ significantly in structure. The U-shaped hanging ring is a single, bent "U"-shaped rod with no right angles and a single rotation direction, while the UB-shaped plate is a plate-like structure with 90° angles and dual rotation axes, allowing for flexible rotation in various directions. This single difference significantly alters the product's structure, performance, and purpose. Our factory specializes in producing both products to better meet user needs. We look forward to collaborating with you.
