 AAC is made up of one or more strands of hard drawn 1350 Aluminum Alloy.  AAC has had limited use in transmission lines and rural distribution because of the long spans utilized.  Good Conductivity -61.2% IACS  Good Corrosion Resistance  High Conductivity to Weight Ratio.  Moderate Strength Typical Application  Short spans where maximum current transfer is required.  The excellent corrosion resistance of aluminum has made AAC a conductor of choice in coastal areas.  Because of its relatively poor strength-to-weight ratio, AAC has seen extensive use in urban areas where spans are usually short but high conductivity is required.  These conductors are used in low, medium and high voltage overhead lines.

 AAAC are made out of high strength Aluminum-Magnesium-Silicon alloy.  AAAC with different variants of electrical grade Alloys type 6101 and 6201.  These conductors are designed to get better strength to weight ratio and offers improved electrical characteristics, excellent sag-tension characteristics and superior corrosion resistance when compared with ACSR.  Equivalent aluminum alloy conductors have approximately the same ampacity and strength as their ACSR counterparts with a much improved strength-to-weight ratio, and also exhibit substantially better electrical loss characteristics than their equivalent single layer ACSR constructions. The thermal coefficient of expansion is greater than that of ACSR.  As compared to conventional ACSR, lighter weight, comparable strength & current carrying capacity, lower electrical losses and superior corrosion resistance have given AAAC a wide acceptance in the distribution and transmission lines. Features  High strength to weight ratio  Better sag characteristics  Improved electrical properties  Excellent resistance to corrosion  Specifications  Higher Tensile Strength  Excellent Corrosion Resistance  Good Strength to Weight Ratio  Lower Electrical Losses  Moderate Conductivity –52.5% IACS Typical Application  Transmission and Distribution applications in corrosive environments, ACSR replacement.

 Aluminum Conductor Steel Reinforced (ACSR) is concentrically stranded conductor with one or more layers of hard drawn 1350-H19 aluminum wire on galvanized steel wire core.  The core can be single wire or stranded depending on the size.  Steel wire core is available in Class A , B or Class C galvanization for corrosion protection.  Additional corrosion protection is available through the application of grease to the core or infusion of the complete cable with grease.  The proportion of steel and aluminum in an ACSR conductor can be selected based on the mechanical strength and current carrying capacity demanded by each application.  ACSR conductors are recognized for their record of economy, dependability and favorable strength / weight ratio. ACSR conductors combine the light weight and good conductivity of aluminum with the high tensile strength and ruggedness of steel.  In line design, this can provide higher tensions, less sag, and longer span lengths than obtainable with most other types of overhead conductors.  The steel strands are added as mechanical reinforcements.  ACSR conductors are recognized for their record of economy, dependability and favorable strength / weight ratio.  ACSR conductors combine the light weight and good conductivity of aluminum with the high tensile strength and ruggedness of steel.  In line design, this can provide higher tensions, less sag, and longer span lengths than obtainable with most other types of overhead conductors.  The steel strands are added as mechanical reinforcements.  The cross sections above illustrate some common stranding.  The steel core wires are protected from corrosion by galvanizing.  The standard Class A zinc coating is usually adequate for ordinary environments.  For greater protection, Class B and C galvanized coatings may be specified.  The product is available with conductor corrosion resistant inhibitor treatment applied to the central steel component.
