Description

An overhead device for a suspended transmission line

technical field

The invention relates to an online device for a suspended transmission line, belonging to the field of transmission line erection tools and equipment.

Background technique

With the requirement of long-distance power transmission, a large number of high-voltage transmission lines need to be suspended and erected through power poles and towers. Due to the lack of professional construction equipment, in traditional construction, it is often necessary to use large-scale hoisting engineering machinery, or rely on construction personnel to manually lift it, resulting in high construction costs and low construction efficiency in traditional construction. In addition, personal and equipment injury accidents occur. At the same time, due to the heavy weight of the power cable, after it is suspended in the air, it will cause serious sagging due to its own weight, resulting in the distance between the power cable and the ground being less than the national safety regulations. At present, there is no professional response equipment in construction, and construction still needs to be carried out by manpower or large-scale construction machinery or vehicles. As a result, on the one hand, the construction cost is high, the construction efficiency is low, and personal and equipment injury accidents occur. It is also impossible to accurately and effectively ensure the accuracy of the power cable when adjusting the sagging height, resulting in low construction quality and threatening the safety of electricity use.
