Suspension And Fixing: Analysis Of The Role Of Bolt-type Tension Clamps In Line Structures

In overhead power line structures, bolted type strain clamp is used for conductor fixing and cable installation on tension poles, and is a typical structural component of the tension clamp family. As a connecting component, the tension clamp bears mechanical tension in transmission lines and maintains the relative position of the conductor and the tower, making it an important part of the power fitting system. dead end strain clamp is connected to the clamp body with bolts to mechanically lock the conductor, adaptable to aluminum stranded wire or steel-cored aluminum stranded wire of different cross-sections and materials.

Structure and Material Design

For tension pole installation environments, bolt-type tension clamps use high-strength metal materials as the main components. The conductor is pressed into the groove by bolt fasteners, thus forming a reliable fixed state. A typical series, such as the NLL bolt-type tension clamp, can achieve the hanging and tension bearing of aluminum stranded wire and steel-cored aluminum stranded wire on tension poles when applied to 20kV and below overhead lines. The structure typically includes components such as U-bolts, washers, nuts, and clamps. These installation components are manufactured according to industry standard specifications to match the requirements of different conductor diameters and working conditions.

Installation and On-site Coordination

The installation process of the bolted dead end clamp clamp involves placing the conductor in the clamp slot and then gradually tightening the bolts to stabilize the conductor under stress. This installation method does not rely on specialized crimping equipment and can be completed on-site using conventional tools such as wrenches. For tension pole structures, the clamp is typically paired with tension insulator strings to properly transfer tension to the tower equipment. Proper tightening procedures and component selection are crucial for ensuring the stability of the conductor under dynamic loads.
