Reliable U-Shaped Hanging Ring Supplier | Customizable & Durable Power Fittings

Product Detail

Models and specifications

Model naming rules: Starting with "U" or "UL", the number indicates the nominal breaking load (such as the breaking load of U-7 is 69kN).

Common models include U-7, U-10, U-16, etc., applicable to wire cross-sectional areas from 10mm² to 240mm², and the nominal breaking load range covers 70kN to 490kN.

-The main dimensional parameters include inner diameter (d), height (H), bending radius (R), etc. For example, the dimensions of U-7 are d=16mm and H=80mm.

Technical characteristics

Safety: The arc-shaped pressure strips and wear-resistant rings disperse the pressure, reduce local stress concentration, and avoid brittle fracture.

Buffer design: The patented technology uses pneumatic shock-absorbing mechanisms and spring components to achieve multi-stage buffering and enhance impact resistance.

Installation convenience: Bolts, nuts and closed pins are used to ensure a stable connection, and can be used in series to adapt to different scenarios.

Application scenarios of U-shaped hanging rings

1. Power line connection

Used in overhead power lines and substations to connect insulator strings or steel strands with poles and towers to play a fixing and load-bearing role.

Used in conjunction with tension clamps, it is convenient for the construction of the first and last ends of cable erection and shortens the construction period.

2. Construction and maintenance

- During cable construction, the U-shaped hanging ring optimizes the tightening of the wire by adjusting the length, and it is necessary to install the safety bolt to prevent the bolt from loosening.

Suitable for lifting operations under high-voltage environments, its high load-bearing capacity and wear resistance can reduce safety accidents caused by equipment failure.

3. Special scene adaptation

The improved product can cope with complex loads (such as radial and longitudinal tension) and is suitable for power projects with complex terrain or harsh environments.

- Some models (such as UL type) are extended designs to adapt to insulators or hardware of different sizes.
