5 Sheaves Stringing Blocks for four bundled conductors
Item No. Model Working Load (KN) Conductor Range (mm) Material of sheave Weight (kg)
10128 SHWQN660 60 ≤30 mm All Nylon 110
Application: It is used for four bundled conductors stringing. Sheave size: Ø660 X Ø560 X 100
All the conductor sheaves  are made of high strength nylon, the central sheave is specially designed with high strength, it is good for passing both of pilot steel wire rope and conductors. 
All the sheaves are mounted on high strength heavy duty ball bearings.
The frame of stringing blocks is made of galvanized steel. Breaking Load: 3 Times of working load.
Option: The central sheave can be changed to steel sheave.


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)
18202A 10 70.00 Φ2.3 1960 350
18212A 22 320.00 Φ4.8 1960 1500
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.
