Comparative Analysis of ACSR and HTLS Conductor

In India, ACSR (Aluminum Conductor Steel Reinforced) and AAAC (All Aluminum Alloy Conductor) are most commonly used conductors for transmission lines. To transfer bulk power from long distance and to meet the increased load demand either we have to construct the new UHV or EHV transmission lines or to uprate the existing transmission line. Uprating of transmission lines i.e. modifications in the existing transmission line to enable the increased current flow limits. Making a new transmission lines also have few constraints: ROW constraints (Lack of availability of corridors for construction of new transmission lines due to High Population Density, Forest/ Ecology conservation) and Time constraints
