Description

Technical Field

[0001] This utility model relates to the field of cable installation technology, specifically to a cable installation device for power transmission towers. Background Technology

[0002] Power transmission towers are tower-shaped structures used for power transmission. Their structural characteristic is that all tower types are space truss structures, with the main members composed of single equilateral angle steel or composite angle steel. When installing cables on power transmission towers, cable fixing components are needed to secure the external cables, ensuring stable placement and use.

[0003] Currently, existing cable installation devices for power transmission towers typically use metal clamps to fix the cables to the towers. During installation, due to the small contact area between the narrow metal clamps and the cables, the metal edges are prone to rubbing and cutting the cable sheath under long-term vibration or wind, leading to insulation damage, water ingress, or even breakage. While wide metal clamps can distribute pressure, their large size and increased weight not only occupy transportation space but also increase the burden of high-altitude operations, affecting construction efficiency. This presents a problem where the size of the metal clamps affects installation and cable fixation. Furthermore, existing metal clamps are mostly of fixed sizes, while power transmission towers vary in diameter and structural dimensions, making it impossible to flexibly adapt the clamps to different tower specifications. Multiple models need to be used during construction, which not only increases costs but also affects installation efficiency, resulting in poor versatility of the metal clamps. Utility Model Content
