🏗️ Construction of Underground Cable

Structure of an Underground Cable

Underground cables are made up of various layers to ensure safety and durability. The main parts include:

• Conductor: Made of materials like copper or aluminum to carry electricity efficiently.
• Insulation: Prevents current leakage and protects the conductor. Common materials include PVC, XLPE, or rubber.
• Metallic Sheath: Protects the cable from moisture and provides an additional layer of insulation.
• Bedding Layer: Provides cushioning and mechanical protection to the sheath.
• Armoring: A layer of steel or aluminum to protect the cable from physical damage.
• Outer Sheath: The final protective layer, resistant to environmental conditions.
