Anti twisting steel rope is specially braided from high strength, high flexible galvanized steel wire. The braided steel strand has high flexibility, complete stability to rotation under tension force. The wire rope is lubricated for long time usage.
It can homogeneously distribute the pressure between the elementary wires. The special rope can increase efficiency during the overhead transmission line stringing work. The rope is packed in steel drum which can be installed directly on the reel winder of puller.
