Steel Strand Fixing Scheme: Analysis Of The Internal Engagement Logic Of Wedge-type Tension Clamps

Metal Core Structure of Wedge-Type Tension Clamps

In power line wiring or communication cable installation, you often encounter cables of different materials. This is where the metal wedge inside the dead end clamp clamp comes in handy. This design utilizes the physical principle of "self-locking." Simply put, the greater the tension on the cable, the deeper the internal metal wedge penetrates. This metal block is much harder than ordinary plastic parts, able to withstand long-term outdoor environmental conditions.

Metal Wedge Compatibility Analysis with Steel Strands

Many people are concerned about whether the ab cable dead end clamp clamp can firmly hold steel strands. In fact, the metal core and steel strands are a perfect match.

• Physical Compatibility: Steel strands themselves are extremely hard, and ordinary nylon wedges are prone to deformation under pressure, leading to slippage. The metal wedge provides sufficient support, allowing the clamping force to be evenly distributed across each wire.

• Friction Coefficient Adjustment: The surface of the metal wedge usually has fine textures. These textures can bite into the gaps in the steel strands during installation, increasing frictional resistance.

• Thermal Expansion and Contraction: The metal wedge core and the steel strand have similar coefficients of expansion, so even during seasonal temperature changes, gaps will not easily form at their junction.

Detailed Installation of Wedge-Type Tension Clamps

When operating the abc dead end clamp clamp, the steel strand ends must be neatly trimmed. Manual pre-tightening after embedding the cable into the groove of the metal wedge is a crucial step.

Tip: During pre-tightening, ensure the wedge is fully inserted into the housing and is not misaligned. If the metal wedge is not aligned, uneven stress during subsequent tension can lead to localized damage to the steel strand.

This metal-to-metal clamping method eliminates the need for complex bolt tightening. Once the wedge is properly engaged, the steel strand will become increasingly stable under its own weight.
