Item No. Model Rated Load (KN) Conductor Range (mm) Material of sheave Weight (kg)
10142 SHSQN822 60 36 mm Nylon 118
Application: The three sheaves stringing blocks could be used for two or three bundled conductors stringing. All the sheaves are made of MC nylon. The central sheave is specially strengthened. it is good for passing both steel rope and conductors. All the sheaves are mounted on ball bearings. The frame of blocks is made of galvanized steel.

Anti twisting braided steel wire rope
Item No. Nominal diameter Min. Breaking Load (KN) Single strand diameter (mm) Normal T/S (N/mm²) Net Weight (kg/1000m)
18208A 16 160.00 Φ3.5 1960 800
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.
