According to the quantity of conductors per phase on transmission line, we have single sheave stringing blocks, 3 sheaves stringing blocks, 5 sheaves stringing blocks and 7 sheaves stringing blocks. The 3 sheaves and 5 sheaves stringing blocks can be used for both 2 or 3 conductors and 4 or 5 conductors stringing on transmission line.

We have different structure for 3 sheaves or 5 sheaves stringing blocks, e.g. normal structure stringing blocks and detachable stringing blocks. For normal structure stringing blocks, we also have designed Tandem type stringing blocks, for the big corner tower and big span towers.

Some special stringing blocks are also used in stringing operation: such as helicopter stringing blocks, cross arm mounted stringing blocks, Hold down stringing blocks, Universal Hook type stringing blocks etc.

Different structure of stringing blocks make the installation of pilot wire rope and conductor easier and faster, also reduce the work load on overhead line. Customers could select suitable stringing blocks according to their requirement.
