Choosing the right conductor is crucial because it balances several key engineering considerations:

• Mechanical Strength: For long-distance, high-voltage transmission lines, the conductor must be strong enough to withstand high tension, heavy wind loads, and ice accumulation. This is why ACSR is often the preferred choice.

• Conductivity: The conductor must efficiently transmit electricity with minimal resistance to reduce power loss and heating. All aluminum-based conductors excel in this regard.

• Cost and Weight: Lighter and more affordable conductors like AAC are ideal for short-span distribution projects, where a simpler support structure is sufficient.

• Corrosion Resistance: In coastal or polluted industrial environments, a corrosion-resistant alloy like AAAC can significantly extend the line's lifespan.
