Description

[0001] The utility model relates to the technical field of power equipment, concretely is a kind of power cable installation lead clamp. BACKGROUND

[0002] With the rapid development of electric power industry, cable plays an increasingly important role in power system. In order to ensure the stable operation and safety of power system, the installation process of power cable is crucial. In this process, cable clamp as a key tool to fix cable, its performance and design directly affect the installation efficiency and safety of cable. However, the existing cable clamp design has certain limitations, especially in the face of complex installation environment, such as two cable staggered laying, the deficiency of prior art is particularly obvious.

[0003] The cable clamp commonly seen in the market at present is mainly composed of an upper clamp and a lower clamp, which fixes the cable by docking. This kind of clamp performs well in fixing single cable, but it is not up to the task when two cables need to be staggered laid. As shown in the figure, when the second cable covers the first cable, in order to ensure the stability of the staggered point of the two cables, four clamps are often used for fixation. This not only increases the material cost, but also increases the complexity and labor intensity of installation, and also has higher requirements for installation space. Figure 1

[0004] In addition, the existing cable clamp rarely considers the adaptability problem under different installation environments, especially when the clamping angle needs to be adjusted according to the laying direction of cable. The fixing method of traditional clamp is too rigid to be flexible, which not only affects the installation efficiency of cable, but also may cause cable damage or unstable fixation due to improper clamping, thereby affecting the safe and stable operation of power system.

[0005] Therefore, it has become an urgent problem in the industry to develop a new type of power cable installation lead clamp to improve the efficiency and safety of cable installation and reduce the installation cost. CONTENT OF THE UTILITY MODEL
