What are the latest advancements in "Conductor Pulling Grips" for various conductor types, including delicate ones like OPGW?
2025-07-20Conductor pulling grips are critical for secure and non-damaging attachment, and recent advancements have focused on enhancing their versatility, strength, and gentle handling capabilities:
-
Material Innovation for Gentle Grip: For sensitive conductors like OPGW (Optical Ground Wire) and HTLS (High-Temperature Low-Sag), grips now utilize advanced materials like high-strength aramid fibers (e.g., Kevlar) or finely woven stainless steel meshes. These materials distribute the pulling force more evenly over a larger surface area, preventing localized stress that could crush optical fibers or composite cores.
-
Adjustable Jaw/Mesh Systems: Some modern grips feature adjustable or interchangeable jaw inserts or mesh sections to accommodate a wider range of conductor diameters with a single tool, increasing versatility and reducing the number of specialized tools needed.
-
Integrated Swivels & Shoulders: Many grips now come with integrated anti-twist Swivels directly incorporated into their design, providing a seamless connection to the pulling rope while effectively preventing torsional forces from damaging the conductor. "Shoulders" or reinforced leading edges protect the very end of the cable from abrasion or damage as it passes through obstacles.
-
Non-Conductive Options: For certain applications, non-conductive grips made entirely from high-strength synthetic materials are available, adding an extra layer of safety.
-
Enhanced Durability & Corrosion Resistance: Grips are increasingly made from higher-grade galvanized steel or stainless steel, with improved manufacturing processes ensuring greater longevity and resistance to corrosion in diverse environmental conditions.
-
Quick-Release Mechanisms: While maintaining a secure grip under load, some designs incorporate features for easier and quicker release after the pull is completed, improving efficiency.
These advancements ensure that pulling grips provide a reliable and safe connection for all conductor types, from robust bare cables to the most delicate optical ground wires.
