What are the advantages of using "non-metallic stringing blocks" or "composite stringing sheaves" for sensitive cables like OPGW or ACCC?
2025-07-21The trend for sensitive conductors is towards "non-metallic OHTLstringingequipment.com/Stringing-Blocks--Sheaves.html target='_blank'>Stringing Blocks" or "composite stringing sheaves." These accessories offer significant advantages:
-
Reduced Conductor Abrasion: Materials like high-grade nylon, polyurethane, or other composites are much softer than metallic sheaves, minimizing friction and preventing scratches or damage to the conductor's outer strands or special coatings (e.g., ACCC).
-
Lighter Weight: Non-metallic materials are inherently lighter, making the blocks easier to handle and install, especially at height.
-
Electrical Insulation: Provide an additional layer of electrical insulation, enhancing safety in certain stringing scenarios.
-
Corrosion Resistance: Immune to rust and corrosion, extending their lifespan in harsh environments.
These specialized blocks ensure the integrity of high-performance and delicate conductors throughout the stringing operation.
