Description

Technical Field

[0001] The invention belongs to the technical field of ground wire hanging point structures, and in particular relates to an anti-tilt ground wire hanging point structure and a multi-circuit power transmission tower. Background Art

[0002] Overhead lines primarily refer to overhead open lines, which are installed above the ground and use insulators to secure transmission conductors to towers erected on the ground to transmit electricity. Their main components include conductors, lightning arresters, towers, and insulators. Because overhead lines are installed above the ground, they facilitate routine maintenance and overhaul, and their construction costs are lower than those of underground cable lines. Ground wires are grounding conductors used for power transmission and play a crucial role in overhead lines. Their primary function is to provide safe grounding protection for the power system and stabilize the system's ground potential. When a fault occurs in the power system, a large amount of current will flow through the ground to the fault point, reducing the grounding resistance. Excessive current can cause personal injury or equipment damage. Ground wires provide a low-resistance grounding path, absorbing fault current and reducing the ground potential, thereby protecting personal safety and ensuring the integrity of equipment. Ground wires can be divided into various types based on their material and shape, including metal ground wires, steel-core aluminum stranded wires, and composite ground wires. Steel-core aluminum stranded wires, due to their high strength and excellent conductivity, are widely used in high-voltage transmission lines and highway collector lines. Attaching ground wires to towers requires operators to work at height, which is inefficient and poses safety risks. Therefore, it is necessary to provide a tilt-resistant ground wire attachment point structure and a multi-circuit transmission tower. Summary of the Invention
