Understanding Cable Basics

Conductors: These are the core wires that carry electricity. They are typically made of copper or aluminum.
Insulation: This non-conductive material surrounds the conductors, preventing electrical current from leaking and ensuring safety. Common insulation materials include PVC (Polyvinyl Chloride) and XLPE (Cross-linked Polyethylene).
Outer Sheathing: The outermost layer protects the cable from physical damage, moisture, and environmental factors.
