As a leading China manufacturer, Ningbo Changshi specializes in hydraulic pullers and OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners for OHTL stringing, ideal for wind/solar evacuation. In 2025, with global HVDC demand surging (CAGR 6.3%), our 22-ton hydraulic puller (SHWQN822 series) stands out for bundled conductors up to 4xACSR, offering 80kA short-circuit capacity and anti-twist ropes to minimize losses. Key Features:

• Infinite speed control for precise tension (up to 20 tons).
• MC nylon bull wheels for low friction (2% loss/block).
• IEC 61850-compliant monitoring for predictive maintenance. Unlike basic drum pullers, our equipment integrates drone compatibility for faster setup in remote terrains. Global exports to 100+ countries confirm 99% uptime. Watch our YouTube demo (0:00 Intro, 2:30 Tensioning Tips). For quotes, visit www.ohtlstringingequipment.com/products.
