To ensure reliability, dead end clamps undergo rigorous mechanical and electrical testing.
Common Testing Standards:
Tensile Strength Test: Evaluates maximum load-bearing capacity.
Conductor Slip Test: Ensures conductors remain securely clamped.
Salt Spray Corrosion Test (ASTM B117): Tests resistance to moisture and rust.
UV Exposure & Weathering Test (IEC 61284): Ensures performance under extreme sunlight.
Torque Load Test (NF C33-041): Validates fastening strength under repeated use.
Reliable cable dead end clamps meet or exceed these industry standards to ensure performance and durability.
The Importance Of Dead End Clamps
The use of dead end tension clamps has significantly enhanced cable connection and fixation, reducing cable movement or vibration and ensuring line stability. This is critical for maintaining the integrity of the cable system, which plays an important role in electrical systems. Dead End Clamps are also critical for guaranteeing the durability and safety of overhead wire systems. When exposed to external interference without the use of clamps for fixation, overhead wires may encounter loose connections, excessive sagging, and even cable breakage, resulting in system failures, inability to work normally, and losses.
In addition, dead end clamps are made of high-strength materials such as aluminum alloys, and can still ensure their stability and tensile strength in harsh environments such as storms, heavy snow, and exposure to the sun. Frequent inspection and maintenance are not required, which greatly reduces the operating and maintenance costs of the entire system.
Installation And Maintenance Of Dead End Clamps
If you want the dead end clamp to play its duty properly and stably, and to ensure its service life, the correct installation processes and subsequent maintenance inspections are important.
Preparation: This is a necessary step before beginning anything. First, gather the necessary equipment for installation and the clamps we will use, and ensure that the clamps satisfy the required size and requirements.
Open the tension clamp: Remove the tension clamp and unfold the structure.
Set at the end of the line: Insert the cable conductor to be fixed into the designated location of the dead end clamp and set it at one end of the line.
Clamp the wire: Using pliers, clamp the wire into the tension clamp to ensure that it is well fastened.
Fix the upper end: When the cable and the clamp are fixed, use appropriate tools (such as a winch or wrench) to tighten the upper cable to ensure that the clamp applies appropriate tension.
Inspection and maintenance: Ensure that there is good electrical contact between the contact surface of the wire and the clamp, and regularly check the clamp for signs of wear, corrosion or damage. For worn and fixed clamps, we should replace them in time to ensure the reliability and safety of the system.
Application Of Dead End Clamps
Dead End Clamps are widely employed in many sectors and areas, primarily including:
Power transmission and distribution lines: mainly cables fixed in low-voltage and medium-voltage overhead lines.
Communication line: In the communication line, dead end Clamp is used to fix the optical cable or cable on the pole or other supporting structures to protect the optical cable or cable from being affected by tension and external forces.
Railway catenary: In the railway catenary, dead end Clamp is used to fix the contact wire on the pillar, bear the tension of the contact wire, and ensure the stable position of the contact wire.
Insulated overhead lines: Cables used to fix overhead lines, providing reliable fixation and insulation.
