Headline: Trenchless HDD for Power Cables: Why Urban Utilities Are Choosing Directional Drilling

News Body:
Urban infrastructure projects increasingly favor trenchless HDD (Horizontal Directional Drilling) to install power cables under roads, rivers, and congested corridors. Despite higher upfront costs, HDD often minimizes traffic disruption, reduces reinstatement costs, and shortens permitting timelines.

Project decision points:

• When to choose HDD: river crossings, busy highways, historic city centers and sites with strict environmental restrictions.

• Bore profile & reamer selection: match bore diameter and reamer sequence to cable duct and conduit specs.

• cable handling & reels: use purpose-built reels, OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners and laydown equipment to protect cable sheathing during pullback.

• Pre-construction surveys: geotechnical studies and utility detection are vital to avoid unforeseen obstructions.

Ningbo Changshi supplies cable handling reels, pullers, and HDD-compatible accessories for power cable installation. Our field engineers can advise on bore sizing, pilot/reamer selection and on-site handling best practices.
