In globally AAC, AAAC & ACSR (All Aluminum Conductor, All Aluminum Alloy Conductor & Aluminum Conductor Steel Reinforced) are most used for transmission lines. To transfer bulk power from long distance and to meet the increased load demand either we must construct the new UHV (Underground High voltage) or EHV (Extra High Voltage) transmission lines or to uprate the existing transmission line (Required New Structure- Like all Tower, pool and all other related accessories Including Conductor & New Land). Uprating of existing transmission lines (Required New Structure- Like all Tower, pool and all other related accessories Including Conductor & New Land)..i.e. modifications in the existing transmission line to enable to increased current flow limits. Making 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, waste of fertile land, Forest/ Ecology conservation) and Time constraints.
