About the Product

Aluminum Bare Transmission cables are essential for power distribution through primary and secondary power lines. Installed through overhead distribution channels, these cables are designed to withstand demanding outdoor conditions. Made from resilient 1350-H19 aluminum, some cables are left bare, while others have cross-linked polyethylene (XLPE) or high-density polyethylene (HDPE) insulation for additional protection. The key types of aluminum bare transmission cables include ACSR, AAC, and AAAC, each offering distinct advantages based on application needs.

Key Differences Between ACSR, AAC, and AAAC Cables

ACSR (Aluminum Conductor Steel Reinforced)

• Composition: Steel core surrounded by aluminum strands, providing extra strength.
• Best For: Long spans, high-tension power lines.
• Strength: Highest tensile strength due to the steel core.
• Flexibility: Less flexible than AAC and AAAC.

AAC (All Aluminum Conductor)

• Composition: Entirely aluminum strands, no steel core.
• Best For: Shorter spans and high-conductivity applications.
• Strength: Lower tensile strength, ideal for urban distribution.
• Flexibility: Very flexible and easy to handle.

AAAC (All Aluminum Alloy Conductor)

• Composition: Aluminum alloy (6201-T81) for better strength and corrosion resistance.
• Best For: Medium spans, corrosive environments.
• Strength: Stronger than AAC, but not as strong as ACSR.
• Flexibility: Balances flexibility and strength.
