Reasons For The Application And Structural Analysis Of Bare Conductors In Wedge-shaped Tension Clamps
As a commonly used accessory in power distribution and transmission lines, the design characteristics of dead end clamp overhead line are highly compatible with the physical properties of bare conductors. In practical engineering, dead end clamp with eye hook can form a stable connection with bare conductors, adapt to conductors of different diameters and current carrying capacities, and ensure the stability and safety of the line structure.
Structural Matching and Tension Distribution
The dead end loop clamp adopts a conical clamping structure, which can automatically generate friction through wedge clamping when the conductor is under tension. This design allows the conductor to maintain its original shape under stress, while maintaining clamping reliability under tension changes. For bare conductors, the surface has no insulation layer, and direct contact with the metal clamp can form a good frictional fit, reducing the risk of slippage.
During the specific installation process, the wedge-shaped tension clamp can be gradually fixed along the conductor direction, so that the clamp is evenly stressed on the conductor surface. This operation can be divided into three aspects:
-
Check whether the conductor surface is clean, free from corrosion or damage.
-
Place the conductor into the clamp slot, ensuring full contact between the conductor and the clamp.
-
By applying appropriate tension, the wedge locks the conductor under stress, achieving a stable tension distribution.
Conductivity and Durability Considerations
Bare conductors bear the primary responsibility for conductivity in transmission lines. Wedge-shaped tension clamps, in direct metal-to-metal contact with the bare conductor, facilitate maintaining conductive continuity. The clamp material is typically treated with anti-corrosion coatings to adapt to various climatic conditions and long-term usage requirements. Because bare conductors lack an insulation layer, wedge-shaped tension clamps can fully utilize their self-adaptive clamping performance, maintaining long-term reliability without affecting the conductor's electrical properties.
