3. 5 Sheaves Stringing Blocks for four bundled conductors

Item No.


Working Load (KN)

Conductor Range (mm)

Material of sheave

Weight (kg)




≤46 mm

All Nylon


Application: It is used for four bundled conductors stringing. Sheave size: Ø1040 X Ø900 X 125

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.


4. 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)













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.

5. Aluminum alloy Conductor come along clamp

Item No.
