The Double Pulley Replace Roller plays a pivotal role in the replacement process of old earth wires with new OPGW cables. The installation of rollers is done while stringing OPGW on a live line, with a distance of 10-15 meters on the pulling rope. The primary function of these rollers is to rotate the old ground wire with new OPGW cable during the replacement process without any loosening or vibration.

Assuming the live line condition of overhead transmission lines, Double Sheave Replace Rollers offer an effective means to replace old earth wires with new OPGW cables. To meet the varying needs of our customers, we offer diverse designs and materials.
The OPGW HANGING ROLLER is a product commonly used in the power industry. It is made of MC nylon wheels, which have lightweight properties, enhance wear-resistant capabilities, and do not cause any damage to the wire.
Aluminum wheels are also used for this product; however, customization is required for manufacturing. The preference for MC Nylon wheels is due to their superior properties in the context of their affordability and efficiency.
For the installation and maintenance of OPGW (Optical Ground Wire) cables on transmission lines, specialized equipment known as OPGW double sheaves support rollers is used. These support rollers have dual sheave design that is used to support and guide OPGW cables. They come with smooth-rolling bearings that minimize cable friction and have protective liners to prevent cable damage.
OPGW double sheaves support rollers are typically manufactured using lightweight and durable aluminum alloy. These rollers are used for cable stringing operations, temporary support during installation, protecting OPGW from damage during pulls, and maintaining proper bend radius.
During installation, OPGW double sheaves support rollers must be correctly positioned on support structures, properly rated for cable weight, and regularly inspected for their condition. Proper alignment is essential to prevent cable stress.
