Description

Technical Field

[0001] The invention belongs to the technical field of spacer bar installation, and in particular relates to a pulley structure for installing spacer bars of an overhead power transmission line. Background Art

[0002] Overhead transmission lines are power facilities in which transmission conductors are mounted on towers with insulators and hardware, maintaining a certain distance from the ground and buildings. Compared to underground cables, overhead transmission lines offer lower construction costs and faster construction times, making them suitable for long-distance, high-capacity power transmission. Their construction is relatively simple, making it easier to detect faults and potential hazards, facilitating timely repair and resolution. Spacers are a commonly used protective hardware in overhead transmission lines. In split conductors, spacers maintain spacing between sub-conductors to meet electrical performance requirements and reduce surface potential gradients. In short-circuit situations, spacers prevent electromagnetic attraction and collision between conductor bundles, ensuring safe line operation. Wind-induced conductor galloping is common, and spacers, by increasing the rigidity between conductors, effectively suppress this galloping and reduce vibration and fatigue damage. For multi-strand high-voltage transmission lines, the large size and weight of spacers make it difficult for workers to work at height. Therefore, a pulley structure for installing spacers in overhead transmission lines is crucial. Summary of the Invention
