Product Description:
The Double Pulley Replace Roller is a tool used to replace old earth wires with new OPGW cables. The device is designed to be installed with a distance of 10-15 meters on the pulling rope, when stringing OPGW on a live line.
Its primary function is to rotate the old ground wire with new OPGW cable without resulting in any looseness or vibration. This is important as it helps to ensure the safety and stability of the transmission line during the replacement process.

Technical Parameters:
The OPGW HANGING ROLLER is a commonly used component in power line construction. This component is essential in the placement and guiding of overhead ground wire cables. The construction of these rollers varies, but the most common is the use of MC nylon wheels.
MC nylon wheels offer many benefits such as being lightweight, durable, wear-resistant and most importantly, they don't damage the wire. These wheels are ideal for the function they serve and have become the standard for this type of component.
However, there are certain situations where the OPGW HANGING ROLLER may need to be customized. For example, if for some reason the MC nylon wheels are not suitable, or if the roller is not compatible with the wire being used, then aluminum wheels must be used instead. In this case, customization is necessary to ensure that the roller functions properly.
Applications:
OPGW (Optical Ground Wire) double sheaves support rollers are specialized equipment designed for the installation and maintenance of OPGW cables on transmission lines. These rollers serve as a support system for cable stringing operations, temporary support during installation, and maintaining proper bend radius.
One of the key features of the OPGW double sheaves support rollers is the dual sheave design that provides support and guidance for OPGW cables. The smooth-rolling bearings ensure minimal cable friction, and the protective liner helps prevent cable damage. These rollers are typically made of aluminum alloy for durability and light weight.
For an effective installation, several considerations must be taken into account. The equipment must be appropriately rated for cable weight. Correct positioning on support structures is important to prevent cable stress. Also, regular inspection of roller condition will ensure hitch-free maintenance of OPGW cables. Proper alignment guarantees that the cables are well-protected from damage during pulls.
The OPGW double sheaves support rollers have found diverse applications on transmission lines. From providing dual sheave design support and guidance for OPGW cables to maintaining proper bend radius and preventing cable damage, these rollers are crucial equipment for cable installation and maintenance.
