Description

Technical Field

[0001] This utility model relates to the field of power cable technology, specifically to a reinforced anti-sway overhead cable. Background Technology

[0002] With the widespread adoption and use of overhead cables in power systems, overhead power cables have always been an important component of these systems. However, in areas with high wind speeds year-round, overhead cables often experience significant swaying, posing certain safety hazards to power transmission and product lifespan.

[0003] A search revealed application number CN201921526555.4, entitled "A Wind-Resistant Overhead Cable." This application addresses the issue that traditional overhead cables, operating year-round in high-wind areas, experience significant tensile stress. The cable swings considerably, and contact with surrounding trees or other obstacles reduces the lifespan of the insulation layer. This impacts product quality, safety, and ultimately, power transmission. The proposed solution utilizes upper and lower clamping ends to hold the cable, with extensible upper and lower buffer springs for more stable clamping. These springs can accommodate cables of different diameters, preventing excessive compression during clamping. Elastic pads at the contact surfaces between the clamping components and the cable allow for free axial twisting, preventing torsional stress during use. Considering the specific operating environment, the cable features a streamlined design to effectively reduce wind resistance. This invention reduces the swaying amplitude of the product during operation. Additionally, the product employs an insulated design, effectively improving its insulation performance and service life. However, this application changes the conventional cable cross-section to a flat shape, making it incompatible with traditional installation tools and requiring specialized fixing tools, thus complicating installation and use. Furthermore, the streamlined cross-section design, with one end larger than the other, means that different wind directions will affect different ends, leading to inconsistent wind resistance reduction. Excessive internal filling material also results in excessive overall weight and greater inertial force, causing installation and use difficulties and reducing anti-sway performance. Further improvements are possible.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

Edge reinforcing ropes are fixedly connected to both ends of the cable body, and a weight-reducing groove is opened between the edge reinforcing ropes and the insulating filler inside the cable core. The vertical cross-section of the cable body is spindle-shaped.
