All Aluminium Conductor (AAC): is made up of one or more strands of hard drawn Aluminium Wires. The EC grade Alloy Conductor has a minimum conductivity of 61.2% IACS.
Aluminium Conductor Steel Reinforced (ACSR): These are concentrically stranded conductor with one or more layers of hard drawn Aluminium wire on galvanized steel wire core which are coated with zinc with Class A Coating. The core can be single wire or stranded depending on the size of the conductors.
All Aluminium Alloy Conductors (AAAC): These are made out of high strength Aluminium-Magnesium-Silicon alloy. As compared to conventional ACSR, AAAC are of lighter weight, comparable strength & current carrying capacity, lower electrical losses and superior corrosion resistance, This has given AAAC a wide acceptance in the distribution and transmission lines.. This conductor has a minimum conductivity of 52.5% IACS.
Aluminium Alloy Conductor Steel Reinforced Conductors (AACSR): is a concentrically stranded conductor composed of one or more layers of Aluminium-Magnesium-Silicon alloy wire stranded with a high-strength coated steel core. AACSR Conductors have approx. 40% to 60% more strength than comparable standard ACSR with only 8 to 10% decrease in conductivity.
Aluminium Conductor Aluminium Alloy Reinforced Conductor (ACAR): is formed by concentrically stranded Wires of Aluminium on high strength Aluminium-Magnesium-Silicon (AlMgSi) Alloy core. ACAR has got a better mechanical and electrical properties as compared to an equivalent conductors of ACSR,AAC or AAAC. A very good balance between the mechanical and electrical properties therefore makes ACAR the best choice where the ampacity , strength , and light weight are the main consideration of the line design. These conductors are extensively used in overhead transmission and distribution lines.
Aluminium Conductor Aluminium Clad Steel Reinforced (ACSR/AW or ACSR/AS): are concentrically stranded conductors with one or more layers of hard drawn Aluminium wires on Aluminium Clad steel wire core. The mechanical properties of ACSR/AS conductors are similar to ACSR conductors but offers improved ampacity and resistance to corrosion because of the presence of Aluminium clad steel wires in the core. These conductors are better replacement for ACSR conductors where corrosive conditions are severe.
High Conductivity Alloy Conductor (AL 59, AL 57, AAAC 1120 etc): These are low resistance High Conductivity alloy conductors with excellent electrical characteristics, excellent sag-tension characteristics and superior corrosion resistance to that of ACSR. As compared to ACSR they have lighter weight, comparable strength and current carrying capacity, lower electrical losses and superior corrosion resistance have given this conductor wide acceptance as a transmission conductor. It has found limited use, however, as a distribution conductor.
High Temperature Thermal Resistant Alloy Conductor (TACSR, TACSR/AW,TACIR/AW etc.) These are high ampacity conductors with inner core composed of galvanized steel, Al. clad Steel, Al. clad Invar Steel etc. & outer layer composed of thermal resistant aluminium alloy.
Aluminium Conductor Steel Supported (ACSS and ACSS/TW): is constructed of fully annealed Aluminium wires formed into a Round or trapezoidal shape. The Aluminium wires are stranded around a steel core of seven or more wires as described in ASTM B-856 & ASTM B-857.ACSS & ACSS/TW can be designed with both equal area or equal diameter, compared to conventional round stranded conductors, to optimize line design options.
The improved conductor can operate continuously at temperatures up to 250°C without loss of strength; its sag is less than that of conventional composite conductors; final sags are not affected by creep; it has excellent self-damping characteristics.View PDF
High Temperature Super Thermal Resistant Alloy Conductor (STACIR/AW) : These are high ampacity conductors with inner core composed of galvanized steel, Al. clad Steel, Al. clad Invar Steel etc. & outer layer composed of thermal resistant aluminium alloy. These can operate upto 210°c degree with specified strength loss, Can carry 100% more current as that of ACSR of the same size. For uprating lines , no modifications or reinforcement is required to the existing towers.View PDF
Gap-type Conductor – GTACSR/GZTACSR : These conductors have a special construction feature with a small gap filled with grease between the high strength steel core and the thermal resistant Al-Zr alloy conductive layers. Installation method of GZTACSR is well but requires skilled specialists because at the time of sagging, a special sagging method is required to apply all the tension to the steel core only. Gap-type conductors are particularly suitable to replace ACSR conductors in flat lands or in any case with small difference in level.
GSW Earth Wire, Stay Wire, Guy Wires, Spaces Cables, etc. are used as overhead ground wire or static wire on transmission lines, as pole or structure guy wires, and as messenger cable for field-erected aerial cable.View PDF
