OPGW Stringing Equipment and Tools

OPGW Stringing Equipment and Tools

OPGW (Optical Ground Wire) stringing equipment and tools are specialized devices used for the installation of optical ground wire cables on overhead transmission lines. These tools facilitate new installations as well as live line reconductoring or replacement work.

Key Equipment and Tools for OPGW Stringing

• Hydraulic Puller Tensioners: These are essential for applying controlled tension to the OPGW cable during stringing. For example, the SA-YZ30A hydraulic tensioner features wear-resistant MC nylon lining on its bullwheel, infinitely variable tension control, and an automatic spring-applied hydraulic brake for safety in case of failure. It supports tensioning up to 30 kN and is widely used for OPGW and ADSS cable stringing.

• Mobile Traction Machines: Machines like the ZZC350 provide traction for pulling OPGW cables at speeds up to 17 m/min with a climbing angle capability of 31º and horizontal tensile strength of 350 N. These are used for live line installation and new transmission line setups.

• Stringing Blocks and Pulleys: OPGW-specific pulleys such as the SHG660 and other overhead transmission line stringing blocks help guide the cable during installation, minimizing friction and preventing damage.

• Come Along Clamps: Tools like the SKG-1.6 and SKG-2.5 come along clamps are designed for pulling OPGW cables up to initial sag tensions. They have extruded aluminum bodies for strength, double-lock nuts with cotter pins, and angled bails to protect the cable from damage. They require regular maintenance and testing to ensure safety and performance.

• Anti-Twist Tension Stringing Tools: These tools prevent cable twisting during installation, which is critical for maintaining the integrity of the optical fibers inside the OPGW cable.

• Fiber Optic Cable Socket Grips: These grips secure the cable ends during pulling operations to avoid slippage and damage.

• Support Rollers and Running Boards: Devices such as live line double sheave support rollers and head running boards (e.g., model ZB1) assist in smooth cable handling and tension distribution during stringing.

Additional Accessories and Safety Equipment

• Tubular Gin Poles, Wire Rope Grippers, Hoisting Tackles, and Cable Reel Stands: These support the physical handling and positioning of cables and equipment on site.
