[0002] ‌The wind-resistant cable of the transmission tower is a device used to enhance the stability and safety of the transmission tower under strong wind conditions. It mainly prevents the tower from deflecting or collapsing under strong winds by increasing the wind resistance of the tower, thereby ensuring the safe operation of the transmission line.‌ For example, the Chinese authorized patent with announcement number CN217480947U (a wind-resistant high-voltage steel pipe transmission tower): includes a tower body, a cross arm 1, a cross arm 2, a cable rack, a base, a pedestal, a cable, a fixing seat, a shock-absorbing seat and a damper.
