Overhead Aluminium Conductors
Aluminium conductors have achieved wide acceptance all over the world for use in overhead transmission and distribution lines. Generally a steel core is used with the aluminium to give the conductor mechanical strength. This arrangement is termed Aluminium Conductor Steel Reinforced or ACSR. Conductors comprised entirely of aluminium are known as All Aluminium Conductors or AAC.These conductors are extensively used for busbars in outdoor substations where spans are short. All Aluminium Alloy Conductors or AAAC consist of an alloying of aluminium to give a tensile strength in excess of that of AAC, allowing longer spans. These conductors are recommended for coastal areas where severe corrosion is a problem.
Aerial Bundle Conductors (ABC)
600/1000V Cable System
Self-supporting system consists of four cores of hard-drawn stranded and compacted aluminum conductors of equal cross-section and insulated with carbon-loaded XLPE to ensure UV protection. All cores strained equally. Supporting core system consists of three phase cores of hard-drawn stranded compacted aluminium conductors insulated with carbon- loaded XLPE laid up around an aluminium-alloy supporting core insulated with carbon loaded XLPE to ensure UV protection. Additional sub-conductors optional in both self-supporting and supporting-core systems.
