As a leading manufacturer of power line equipment, we emphasize that the long-term reliability of underground AC cables hinges on meticulous planning and execution. Key best practices include:

• Proper Trenching: Dig trenches to the specified depth (typically a minimum of 600mm) and width, adhering to local regulations. The trench should be wide enough to allow for easy laying and inspection.

• Cable Protection: Utilize durable conduits or ducting (e.g., PVC or HDPE) to protect cables from physical damage, earth movements, and rodent attacks. For direct burial, use a protective backfill like sand or fine soil to cushion the cable from sharp rocks.

• Careful Laying: Avoid excessive pulling or bending, which can damage the cable's insulation. We recommend using specialized cable pullers and rollers to maintain a minimum bending radius, as per industry standards (e.g., 15 times the cable's outer diameter).

• Warning Tapes: Install warning tapes above the cables at a specified distance to alert future excavators of their presence, preventing accidental damage.

• Proper Sealing: Use waterproof connectors and sealing materials to prevent water ingress, which is a major cause of cable faults.
