Double Pulley OPGW/Earthwire Exchange Running Board

Double Pulley OPGW/Earthwire Exchange Running Board: Streamlined Upgrades for transmission lines

At Ningbo Changshi Electric Power Machinery Manufacturing Limited, we recognize that modernizing overhead transmission lines often involves the critical task of upgrading traditional earthwires to OPGW (Optical Ground Wire) to integrate high-speed communication capabilities. This "exchanging overhead earthwire with OPGW operation" requires specialized tools that can handle both the removal of old conductors and the precise installation of new fiber optic cables simultaneously, without compromising safety or efficiency. Our Double Pulley OPGW/Earthwire Exchange Running Board (also referred to as a "Double pulley fiber optic cable replacer") is a meticulously engineered solution designed to facilitate this complex dual operation with unparalleled control and protection. This innovative running board is fundamental to minimizing downtime, enhancing safety, and ensuring the seamless transition to an integrated power and communication infrastructure. As a prominent China manufacturer and exporter specializing in comprehensive one-stop supply for both overhead transmission line (OHTL) wire cable conductor tension stringing equipment and underground cable laying equipment, this double pulley exchange board exemplifies our unwavering commitment to providing cutting-edge, durable, and highly efficient solutions that support the critical modernization of power grids worldwide.

The Double Pulley OPGW/Earthwire Exchange Running Board is distinguished by its unique "double pulley" configuration. This design allows for two separate, yet synchronized, pathways for cables. In a typical "exchanging overhead earthwire with OPGW operation," the existing earthwire is threaded through one set of rollers, while the new OPGW fiber optic cable is threaded through the second, parallel set. As the old earthwire is pulled down by a suitable OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner/puller, the new OPGW is simultaneously pulled into its place, often in a single, continuous motion. This "replacer" functionality is crucial for efficiency and safety. The pulleys feature smooth, non-abrasive linings, typically made from high-density nylon or specialized polymers, which are specifically chosen to protect the delicate jacket of the new OPGW cable while allowing the old earthwire to pass through without snagging. This dual-track system ensures controlled movement, prevents kinking, and minimizes friction for both cables during the exchange process. By deploying Ningbo Changshi's Double Pulley OPGW/Earthwire Exchange Running Board, you streamline complex reconductoring projects, enhance worker safety by reducing manual intervention at height, and ensure the pristine integrity of your valuable OPGW fiber optic cables.

Product Features & Benefits:

• Simultaneous Cable Exchange: Unique "double pulley" design allows for the efficient and safe removal of existing earthwires while simultaneously installing new OPGW fiber optic cables, significantly reducing project time.

• Dual Cable Protection: Both sets of pulleys feature smooth, non-abrasive grooves and linings (e.g., high-density nylon) specifically engineered to protect the sensitive OPGW jacket from abrasion and damage, while also ensuring smooth passage for the old earthwire.

• Controlled & Synchronized Movement: Ensures a precise and controlled exchange process, preventing kinking, entanglement, or sudden drops of either cable during the operation.

• High Strength & Durability: Constructed from robust, corrosion-resistant materials (e.g., high-strength aluminum alloy, galvanized steel) ensuring long operational life in demanding outdoor environments.

• Optimized for Overhead Operations: Designed for easy attachment to stringing setups and compatible with various tower structures and stringing methods.

• Reduces Project Time & Cost: By facilitating a single-pass exchange, it significantly cuts down on labor hours, equipment rental time, and overall project costs associated with reconductoring.

• Enhanced Safety: Minimizes the need for manual handling of both old and new conductors at height, significantly reducing risks for line workers.

• Maintains Optical Integrity: Specialized design ensures the OPGW cable is handled with the utmost care, preventing micro-bends or damage to the optical fibers.

• Versatile Application: Can be integrated into various tension stringing setups for earthwire-to-OPGW upgrades.

Product Applications:

Our Double Pulley OPGW/Earthwire Exchange Running Board is an indispensable tool for critical transmission line modernization projects:

• Earthwire to OPGW Conversion: The primary application for directly exchanging existing overhead ground wires with Optical Ground Wire (OPGW) on transmission and distribution lines.

• Line Uprating & Reconductoring: Essential for projects involving the replacement of older conductors with new ones that integrate fiber optic communication capabilities.

• Power Grid Modernization: Supports initiatives to enhance grid communication, monitoring, and control through the deployment of OPGW.

• Live Line Replacement (with proper procedures and isolation): Can be part of a carefully planned system for replacing earthwires with OPGW under certain conditions.

• Any Project Requiring Simultaneous Cable Exchange: Applicable wherever the controlled, simultaneous removal of one overhead cable and installation of another is required, particularly for sensitive fiber optics.

• Long Span Installations: Ensures consistent performance over extended spans where precise cable management is crucial.

Technical Data Sheet (Example Specifications - please refer to specific model for exact data):

Note: It is crucial to select the correct double pulley running board that is compatible with the outer diameters of both the existing earthwire and the new OPGW cable. Always verify the board's Safe Working Load (SWL) against the expected pulling tension. Regularly inspect the pulleys and frame for wear or damage before each use. Please contact us for detailed datasheets for specific models and their exact specifications, compatible cable diameters, and load capacities.
