Description

Technical Field

[0001] The utility model relates to the technical field of electric power installation, in particular to an electric power installation lead clamp. Background Art

[0002] In the construction and maintenance of power lines, lead clamps play a vital role. They are responsible for making stable connections between cables and equipment or between cables.

[0003] The fluctuations of cables in the natural environment, such as cable expansion and contraction caused by wind and temperature changes, can easily lead to displacement between the lead and the clamp. This displacement will not only affect the current transmission efficiency, but more seriously, long-term displacement may cause fatigue fracture at the connection, seriously threatening the safe operation of the power line. In addition, traditional power installation lead clamps are often only suitable for cables of specific specifications or materials. For cables of different specifications and materials, different types of clamps need to be prepared, which undoubtedly increases the complexity and cost of installation and maintenance. In order to solve the above problems, while facilitating the clamping and locking of the cables, the clamping parts can be protected to avoid breakage after long-term use. Moreover, the lead clamp can be applied to cables of various specifications, which is more convenient for use during power installation. For this reason, we propose a power installation lead clamp.
