Description

Technical Field

[0001] The present invention relates to the field of power transmission lines, and in particular to an assembled tension-resistant wire clamp protection device. Background Art

[0002] Strain clamps refer to hardware used to fix conductors to withstand conductor tension and hang the conductors on tension strings or poles. Strain clamps can be roughly divided into two categories according to their structure and installation conditions. The first category: Strain clamps must withstand the full tensile force of the conductor or lightning conductor, and the clamp gripping force must not be less than 90% of the rated tensile force of the installed conductor or lightning conductor, but they do not serve as conductors. This type of clamp can also be removed after the conductor is installed and used separately. This type of clamp includes bolt-type tension clamps and wedge-type tension clamps. The second category: In addition to bearing the full tensile force of the conductor or lightning conductor, the tension clamp also serves as a conductor. Therefore, once this type of clamp is installed, it cannot be disassembled again, and is also called a dead wire clamp. Since it is a conductor, the installation of the clamp must comply with the provisions of the relevant installation operating procedures and be carried out carefully.

[0003] The tension clamp is one of the effective hardware to solve the tension overload problem of transmission lines. Although the traditional tension clamp protection device can effectively fix the transmission line, it is difficult to ensure the effective angle of the transmission line. If the lower transmission line makes a circular pendulum motion for a long time, it is easy to cause damage to the connection position between the tension clamp and the transmission line. For this reason, we have made improvements and proposed an assembled tension clamp protection device. Summary of the invention
