Description

Technical Field

[0002] Overhead cables usually refer to power lines that are erected on the ground and insulated by insulators and air. Compared with underground transmission lines, overhead lines have the advantages of low construction cost, short construction period, and easy inspection and maintenance. Therefore, overhead lines have been the main transmission method adopted by the power industry since its development. However, when overhead lines are used outdoors, their transmission cables will swing when encountering severe weather such as strong winds, thereby changing the overall tension of the transmission cables. If the tension is too large, it will cause damage to the transmission cables or even breakage. The existing treatment method is to erect a hanging wire above the transmission cables, and complete the limit connection between the hanging wire and the transmission cables through multiple hanging devices. During installation, By keeping the transmission cable in a relatively relaxed state and tensioning the hanging wire at the same time, the tension change of the transmission cable when it sways in windy weather can be overcome by the tensioned hanging wire, thereby protecting the transmission cable; however, the existing hanging device has a relatively simple structure, mostly consisting of two sets of connecting iron plates and a plurality of locking screws. When the hanging device of this structure is used, the overall applicability and connection stability are poor. It is easy to slide and displace due to the shaking of the hanging wire during use, thereby affecting the hanging between the hanging wire and the transmission cable; therefore, in order to solve the above problems, it is necessary to develop a hanging device for hanging power overhead cables with reasonable design, convenient adjustment operation and stable and reliable connection.
