The New Design for Low Loss and High Reliability of MEA's Overhead 69 kV and 115 kV Sub-transmission Line in Urban Area

For improving MEA's sub-transmission line which new design to prepare the load increasing by EV car. In the urban area, the sub-transmission line requires installing a few electric poles and more electrical clearance for improve reliability. In this case, MEA design with 34- meters steel monopole and used the composite insulator. Another issue is the changing of conductor type from All Aluminum Conductor (AAC) to High Temperature Low Sag conductor (HTLS) to increase 2-time ampacity and reduce the technical loss by 20.57 kW per circuit-km, equivalent to 2,073.1 kilograms of CO2 emission per month.
