Product Description:
The Double Pulley Replace Roller is a useful tool for replacing old
earth wires with new OPGW cables. When stringing OPGW on live
lines, the rollers are installed at intervals of 10-15 meters on
the pulling rope.
By using the Double Pulley Replace Roller, you can rotate the old
ground wire with the new OPGW cable without experiencing any
looseness or vibrations. This ensures a smooth and efficient
replacement process.
