Tension stringing keeps a constant pull force on the conductor using hydraulic pullers/OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners. It’s best for high-voltage, long-span lines because it precisely controls sag and protects the conductor. Conventional stringing (“pull-and-drag”) is simpler and suits short-span, lower-voltage lines. In difficult terrain or with advanced conductors, tension stringing greatly improves sag control, conductor safety, and overall crew safety compared to non-tensioned methods.
