Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transmission line wiring, in particular to a transmission line wiring device for power grid infrastructure. Background Art
[0002] Power grid infrastructure projects refer to power grid construction projects that follow certain project rules and procedures and a certain amount of investment, with the main goal of completing new construction, expansion, and other expansions of power transmission and distribution capacity. As the backbone grid structure of the power grid, overhead transmission lines have higher requirements in power grid infrastructure. Transmission lines are usually tied to crossbars with iron wires. After long-term use, the elongation arc of the transmission line sags greatly, causing relaxation, which affects the stability of the transmission line.
[0003] In actual use, when the device cannot clamp the wires, the wires may move due to wind, vibration or load changes, affecting the stability of the power grid. If the wires cannot be firmly clamped, they may fall off or shift, which may cause poor contact of the wires, causing short circuits, wire breaks or other electrical failures, and may even pose a threat to personnel safety. Frequent displacement or falling of wires requires constant maintenance, which increases the workload and cost of the maintenance team, and also increases the complexity of power grid operations. If the wiring device needs to be frequently adjusted or replaced to solve the problem of unstable clamping, this will reduce the efficiency of power grid construction or maintenance and delay project progress. Unstable clamping may cause repeated friction and vibration of the wires, which may damage the insulation layer of the wires and shorten the service life of the wires. If the device design cannot adapt to wires of different diameters or types, then in actual use it may not be effectively clamped due to mismatched wire sizes. Utility Model Content
