This insulation is critical for preventing corrosion and ensuring the longevity of the wire.
AU-W's suitability for underground use stems from its unique design and the materials used in its construction. The primary factor is the insulation layer, which is typically made from cross-linked polyethylene (XLPE) or similar materials. These materials are highly resistant to moisture, chemicals, and abrasion, providing a protective barrier against the corrosive elements found in soil. The insulation also prevents electrical leakage and short circuits, which are particularly dangerous in underground environments where moisture is present. Additionally, AU-W wires are often constructed with a thicker gauge than above-ground wires to compensate for the potential heat buildup that can occur when wires are buried. This is because the soil acts as an insulator, trapping heat around the wire. Proper grounding and bonding are also essential for AU-W installations to ensure safety and prevent electrical hazards.
Installing and maintaining AU-W require specific techniques and considerations to ensure its long-term reliability and safety. Proper trenching and burial depth are crucial to protect the wire from physical damage, such as being struck by digging equipment. The depth typically ranges from 18 to 24 inches, depending on local codes and the type of application. Before burying the wire, it’s important to inspect it for any signs of damage to the insulation. Any nicks or cuts should be repaired using approved splicing kits. The trench should be backfilled with soil that is free from rocks and sharp objects, which could potentially damage the wire over time. Regular inspections should be conducted to check for any signs of ground settlement or other issues that could affect the wire. If any problems are detected, they should be addressed promptly to prevent electrical failures or safety hazards. By following these best practices, you can ensure that AU-W installations remain safe and effective for many years.
