The document outlines various types of aluminium conductors, including solid, hollow, and stranded options used in electrical substations. It details the specific characteristics and applications of stranded conductors like AAC, AAAC, ACSR, ACSS, ACCR, and ACCC, highlighting their tensile strength, span length, and corrosion resistance. Different ACSR conductor types and their specifications, including operating voltage and current capacity, are also provided.

9. Stranded Aluminium Conductors;
• AAC – All Aluminium Conductor
• All strands of aluminium with purity 99.7%
• High resistant to corrosion
• Installed in coastal areas
• Lowest tensile strength therefore
permit low span length

10. Stranded Aluminium Conductors;
• AAAC – All Aluminium Alloy Conductor
• All strands of aluminium alloy
• Moderate resistant to corrosion
• Allow more span length than AAC
• Good tensile strength
• Installed at;
• Railway crossing
• River crossing
• Hilly areas

11. Stranded Aluminium Conductors;
• ACSR – Aluminium Conductor Steel Reinforced
• Galvanized steel strands at core;
surrounded by aluminium
strands
• High tensile strength
• Moderate expansion
• Higher span length than AAC
and ACSR conductor
