Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a vertical anti-slip cable for a wind power generation system. Background Art

[0002] As energy and environmental issues become increasingly prominent, the development of renewable energy has attracted more and more attention. Among them, wind power generation, as a renewable energy source, has the advantages of being clean, efficient, and sustainable, and has been widely used and promoted. In wind power generation systems, power cables are important equipment used to connect wind turbines to power grids and are usually laid vertically. However, in variable wind environments, cable slippage often occurs, resulting in reduced power transmission efficiency, even causing safety accidents and increasing the difficulty of laying. Therefore, the development of a vertical anti-slip power cable that can resist slippage and improve power transmission efficiency is of great significance to the stable operation of wind power generation systems.

[0003] The invention patent with publication number CN117352210A discloses a vertical anti-slip cable for a wind power generation system and a preparation method thereof, comprising: a conductor; a co-extruded insulation layer, laid on the outside of the conductor; a sheath layer, laid on the outside of the co-extruded insulation layer; a fiber reinforcement layer, laid on the outside of the sheath layer; an anti-slip sheath, laid on the outside of the fiber reinforcement layer, and a circle of protrusions is arranged on the outer surface of the anti-slip sheath along the circumference of the conductor, and the protrusions are a tooth-shaped structure.

[0004] The above patent can avoid the problem of conductor slippage caused by the cable's own gravity to a certain extent. It is also necessary to ensure that there is no slippage between the cable and the clamp or binding belt. Too tight clamps can also cause damage to the sheath layer and even damage the insulation layer, which can lead to cable breakdown after long-term operation. After laying, it not only requires frequent maintenance but also has operational risks.

[0005] However, the cable of the above patent still has a sliding connection between the surface of the cable and the wind power tower, so the cable may still slip when overcoming gravity. Utility Model Content
