The Core Of Terminal Anchoring: The Design And Positioning Of Bolt-type Tension Clamps.

As a classic type of hardware product, the bolted type strain clamp has a very clear functional positioning: to achieve the "anchoring" of the wire at the terminal. This anchoring effect is similar to the "anchor" of a ship, firmly fixing the conductor to the insulator string of tension towers or angle towers to withstand the enormous tensile force generated during line operation. It is not a simple conductor connection, but a mechanical endpoint.

Anchoring Principle: Mechanical Engagement, Not Conductivity

Unlike compression clamps, which are "dead clamps" that act as conductors, the dead end strain clamp clamp focuses on pure mechanical anchoring. It uses the vertical pressure of the U-bolt to press the conductor tightly into the wavy groove of the clamp, utilizing strong friction to balance the entire tensile force of the conductor. The gripping force of this type of clamp is usually required to be no less than 90% of the conductor's rated tensile strength, but it does not carry current. Therefore, it can be disassembled as needed after installation, providing convenience for line inspection and maintenance.

Structural Orientation and Installation Logic

The installation direction of the bolted dead end clamp has its own inherent logic in order to achieve reliable terminal anchoring. In an inverted clamp design, the boltless side must point towards the conductor end, while the bolted side should point towards the jumper end. This design ensures that the stress is concentrated in a more stable area, preventing clamp deformation due to uneven stress. The internal grooves of the clamp are typically designed with a wavy shape or specific clamping teeth to increase the contact friction with the conductor and prevent slippage due to vibration or creep during long-term operation.
