Description

Technical Field

[0001] This utility model relates to the field of cable fixing technology, specifically to a bypass cable fixing device. Background Technology

[0002] In bypass operations of power systems, ensuring the stable fixation of bypass cables is crucial. Traditional bypass cable fixing methods have many problems. For example, using insulating rope sleeves for fixing is cumbersome and time-consuming, especially when fixing a large number of bypass cables, resulting in extremely low efficiency. Moreover, the knots in the insulating rope sleeves are prone to loosening, causing the bypass cables to sway or loosen during use, seriously affecting the cable's safety performance. In addition, this traditional method requires additional material and labor costs. Therefore, the development of an efficient, stable, and low-cost bypass cable fixing device is urgently needed to meet the growing demands of power operations, improve construction efficiency and quality, and ensure the stable operation of the power system.
