During the power transmission process, dead end clamps are necessary for the stability and safety of the power grid. Dead end clamps fix the conductors at the terminal points of the transmission line and play an important role in both high-voltage and medium-voltage applications.

What is a dead end clamp?
A dead end clamp is an end clamp that fixes the transmission line by wrapping the conductor around the dead end clamp to ensure that the line is firmly connected to ensure that the conductor can maintain a safe and reliable connection when subjected to high tension and external environmental influences.
How to install a dead end clamp?
Before starting the installation, it is necessary to ensure that the power system is completely de-energized. The installer needs to prepare insulating tools and bring the corresponding end clamp parts.
- First find the location where the end clamp needs to be replaced or installed, then loosen all fasteners on the dead end clamp, insert the conductor into the clamp, and ensure that it is properly installed in the jaws or clamp surface.
- After confirming the alignment, tighten the fasteners of the clamp in a sequential and balanced manner, and use a torque wrench to tighten the bolts to the torque setting specified by the manufacturer to ensure the tightness of the installation.
- Ensure that the clamp is in the correct position and the conductor is firmly fixed. Apply tension to the conductor slightly (if safe and possible) to ensure that the dead end clamp is fixed and does not move.
- Clean up the garbage during the installation process to ensure cleanliness, and record the installation location for subsequent maintenance inspections
What are the three types of clamps?
| Rod clamp | Expand or contract to accommodate workpieces of different sizes |
| Spring clamp or clamp | Use two jaws to hold the material firmly in place |
| Angle clamp or band clamp | Adjust the band or strap to apply pressure on all sides of the workpiece |
Different materials of dead end clamps have their unique advantages
Steel dead end clamps: Steel dead end clamps are known for their strength and reliability and are widely used in environments where durability is critical.
Composite dead end clamps: Composite dead end clamps are a lightweight and sturdy alternative, ideal for installations that require mechanical strength and weight reduction.
Insulated dead end clamps: Insulated dead end clamps have enhanced electrical insulation properties to minimize leakage and improve overall system safety.
About the application of dead end clamps throughout power transmission
Overhead transmission lines: Dead end clamps are critical at the terminal points of transmission lines to ensure that the conductors remain firmly fixed.
Distribution networks: In urban and rural environments, dead end clamps maintain the integrity of distribution networks by preventing conductors from sagging and moving.
Railway electrification: Dead end clamps are also used in railway systems to secure overhead wires, ensuring reliable power supply for electrified trains.
Industrial facilities: Factories and large industrial plants rely on dead end clamps to safely manage heavy electrical connections.
Ensuring the long-term use of end clamps requires regular maintenance and inspection. Regular inspection of dead end clamps helps to detect wear or damage early so that timely repairs or replacements can be made. Proactive maintenance of dead end clamps can extend their service life and ensure continued reliable operation of power systems.
