The primary methods for laying 33kV underground cables are direct burial and the draw-in system using ducts or conduits.

• Direct Burial: This method involves laying cables directly into an excavated trench with a bedding of sand and then covering them with protective materials like bricks or concrete tiles before backfilling. It is cost-effective and provides good thermal dissipation.

• Draw-in System: This method utilizes pre-installed ducts or pipes in the trench. The cables are then pulled through these ducts at a later stage. This approach is more expensive initially but offers greater protection, simplifies future modifications or repairs, and is ideal for areas with multiple underground utilities or road crossings.

Our range of cable laying equipment, including Cable Pulling Winches, cable rollers, and cable pulling grips, is engineered to support both methods, ensuring efficient and safe installation.
