Anti-slip Structure Design Of Bolt-type Tension Clamp
In overhead power line engineering, the secure fixing of conductors is fundamental to the stable operation of the system. bolted type strain clamp Through the interaction between the U-bolt and the pressure block, a uniform clamping force is generated on the wire, forming a set of effective fixing mechanisms. This design ensures a tight frictional fit between the conductor and the clamp when under tension, preventing detachment under harsh weather conditions.
Friction Transmission and Conductor Stability
The dead end strain clamp clamp works by the vertical pressure of the U-bolt causing friction between the clamping block and the conductor. This design creates an integrated connection between the clamp and the conductor. The arc segment on the clamp body is a key design element; the larger the contact area between the arc surface and the conductor when under pressure, the more stable the frictional force transmission. During on-site installation, the tightening force of the U-bolt must fully compress the steel core to prevent relative slippage of the conductor under dynamic loads such as wind vibration.
The clamp is made of high-strength aluminum alloy with a high-gloss finish; its material properties determine its compatibility with the conductor. Aluminum alloy wire clamps are characterized by high strength and excellent corrosion resistance. These properties maintain a stable coefficient of friction during long-term service, ensuring that the conductor will not slip or fall off due to reduced gripping force caused by corrosion.
The impact of installation process on anti-slip performance
The correct installation requirement for bolted dead end clamp is that all U-bolts be installed on the jumper side, and no bolts are used for fixing on the load-bearing side. This process requirement directly affects the anti-slipping performance of the wire clamp. Incorrect installation will lead to uneven stress distribution on the conductor under load, causing local overload or even wear of the aluminum sheath.
During on-site construction, operators need to check each U-bolt according to the specifications to ensure that each U-bolt is in the specified position and reaches the designed tightening force. The standard gripping force for bolt-type tension clamps used in 10kV distribution lines should not be less than 65% of the conductor's calculated breaking strength. This standard has been verified through testing and can prevent conductor slippage under various operating conditions.
The curvature radius design of the wire clamp also controls the stress distribution of the conductor during bending. A reasonable curvature radius avoids excessive additional stress on the conductor at the exit point while maintaining sufficient friction. This combination of structural design and process specifications results in a bolt-type tension clamp that can withstand mechanical tension while preventing conductor slippage and detachment.
