Correct Method And Function Of Connecting And Fixing Wedge-type Tension Clamps
A wedge-type tension clamp anchors overhead conductors by utilizing a mechanical advantage where increased tension tightens the internal wedge grip. Correct installation involves cleaning the conductor, inserting it fully into the device casing, and driving the wedge home to prevent slippage and ensure long-term mechanical stability.
Functions of Tension Hardware in Overhead Lines
Industrial power grids rely on a dead end clamp overhead line configuration to withstand high tensile loads. This hardware transfers mechanical tension from the conductor to support structures. Utilizing a dead and clamp mechanism ensures that the cable remains secure under environmental stress, preventing structural failures and maintaining continuous power distribution.
Step-by-Step Installation Process
Step 1: Preparation and Alignment
-
Inspect the conductor for any surface damage, corrosion, or debris before beginning the procedure.
-
Select the matching dead end clamp with eye hook based on exact cable diameter specifications.
-
Align the conductor completely straight to ensure uniform load distribution inside the device during the high-tension pulling phase.
Step 2: Securing the Wedge Mechanism
-
Insert the prepared cable into the main body of the wedge-type tension clamp.
-
Drive the wedge into the casing using an approved copper mallet to prevent component distortion.
-
Verify that the wedge achieves full engagement, leaving a 15mm clearance space at the housing exit for proper seating.
Main Specifications
| Model Type | Conductor Diameter (mm) | Rated Tensile Strength (kN) | Torque Requirement (Nm) |
|---|---|---|---|
| WTC-01 | 9.5 - 12.0 | 45 | 50 |
| WTC-02 | 12.1 - 15.0 | 70 | 65 |
Proper application of a dead clamp ensures grid reliability and minimizes maintenance costs. Following exact mechanical steps guarantees that every wedge-type tension clamp performs at its maximum rated capacity.
