Product Description

Product Description

A strain clamp, also known as a tension clamp or dead - end clamp, is a crucial component in power transmission and distribution systems. It is mainly used to fix and anchor conductors at the tension points of overhead power lines, such as at the end of the line or on tension towers.

Structure and Types

 

• Structure: Generally, a strain clamp consists of a clamp body and fastening components. The clamp body is designed to hold the conductor firmly, while the fastening components are used to connect the clamp body to the tower or other supporting structures.
• Types: There are various types of strain clamps, such as bolted type, compression type and wedge type. Bolted strain clamps use bolts to tighten and fix the conductor. Compression type strain clamps work by compressing the conductor to achieve a firm connection. Wedge type strain clamps utilize the wedge principle to grip the conductor.

Function and Importance

 

• Function: The primary function of a strain clamp is to bear the tension of the conductor. It ensures that the conductor remains in position and does not move or sag due to factors such as wind, ice load and thermal expansion and contraction. In addition, it also provides electrical connection between the conductor and the tower or other grounding devices to ensure the safety of the power system.
• Importance: Strain clamps play a vital role in maintaining the stability and reliability of power lines. If a strain clamp fails, it may lead to conductor breakage, tower collapse and other serious accidents, which will cause significant impact on power supply and social production and life.

Installation and Maintenance

 

• Installation: During installation, it is necessary to ensure that the strain clamp is correctly installed on the conductor and the connection is tight. The installation position should be accurate to ensure that the clamp can bear the tension of the conductor effectively. Professional tools and techniques are required to ensure the installation quality.
• Maintenance: Regular maintenance of strain clamps is also essential. Inspectors need to check the condition of the clamps regularly, including whether there is corrosion, loosening or damage. If any problems are found, timely repair or replacement should be carried out to ensure the safe operation of the power line.
