OPGW (used for telecom/grid integration) requires zero-twist stringing. Essential tools include multi-sheave OHTLstringingequipment.com/Stringing-Blocks--Sheaves.html target='_blank'>Stringing Blocks (often 4- or 5-sheave blocks for bundled OPGW) and high-capacity puller-OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners that maintain fiber integrity. A grounding kit is also critical for live-line work. Portable pilot line winders help start stringing on towers. For example, our OPGW pulley blocks and Tensioners support Kevlar-fiber core conductors and have been proven in wind farm projects (e.g. Prymorska) to ensure safe, twist-free installation.
