Description

Technical Field

[0001] The present invention relates to the technical field of cable suspension components, in particular to a high-altitude cable suspension structure for power transmission. Background Art

[0002] Electric energy transmission refers to a method of transmitting power from one place to another by a power plant or power source. Due to the immaturity of early technology, electric energy transmission mostly used direct current transmission, and later gradually evolved into alternating current transmission. AC transmission has many advantages, reducing losses in power transmission and increasing speed and transmission length.

[0003] In the existing technology, cables are used as carriers for electric energy transmission, and high-altitude cables usually need to be suspended for installation. At present, the common lifting, traction and suspension devices for vertical installation of low-voltage multi-core cables on the market are mostly wire mesh sleeves. The structure and manufacturing process of this type of suspension device are relatively simple. Its principle is to utilize the characteristic that the lifting ring will become tighter and tighter when the end of the wire mesh sleeve is locked. After the phase-to-phase insulation isolation and sealing treatment are performed on the end of the multi-core cable, the wire mesh sleeve is covered on the outside of the cable end and the open end of the mesh sleeve is locked to pull, traction and suspend the cable.

[0004] However, the traditional suspension structure has concentrated pulling force points at the ends, which poses a risk of fracture at the concentrated force points. Summary of the Invention
