The primary methods include: Direct Burial, where cables are laid directly into a trench (requiring trenchers, cable drum trailers, rollers, and backfill compactors); Duct and Conduit Laying, where cables are pulled through pre-installed conduits (requiring duct rodder, cable pullers, cable lubricants, and specialized pulling heads); and Cable Ploughing, an increasingly popular method that buries cables without extensive trenching (requiring cable ploughs, powerful tractors, and precise guidance systems). Ningbo Changshi provides a comprehensive range of equipment for all these methods, enhancing efficiency and minimizing environmental impact.
