An underground power line is more than just a cable; it's a complete system designed for long-term reliability. The key components include:

• Conductor: The core of the cable, typically made of aluminum or copper, that carries the electrical current.

• Insulation: The most critical component. High-quality materials like XLPE (Cross-linked Polyethylene) insulate the conductor, preventing current leakage and protecting it from moisture and chemical damage.

• Conduit: A protective pipe, often made of PVC or HDPE, that houses the cable. It provides a crucial layer of physical protection and allows for easier replacement in the future.

• Accessories: This includes various components that are essential for the system's operation and maintenance, such as joints (splices) to connect cable sections and terminations to connect the underground cable to above-ground equipment like transformers.
