Overhead Stringing Blocks are used for overhead transmisson line conductor or OPGW stringing. We have produced sheave rollers with nylon or aluminum alloy, both kinds of rollers could be lined with neoprene, to protect some special kind of conductors.

Application: It is suitable to string stranded aluminum and ACSR conductors on tangent structures. Compression sleeves, swivel connectors, and pulling rope connectors can pass through the groove. The sheave is made in high strength nylon. The big size 660mm, 822mm, 916mm, 1040mm nylon sheave can be lined with neoprene.
Note:
1. Hook fitting, round eye fitting, and clevis fitting are optional, please specify when ordering. Customized blocks could be supplied on request.
The data in the model means the outer diameter of sheave X width of sheave (mm).
2. All the sheaves are mounted on ball bearings. The frame of blocks is made in galvanized steel.
