An Overview of the Recent Design and Construction of High Voltage Transmission Lines in Sri Lanka

Project Engineer BSc. Eng, C.Eng. MIE (SL) The construction of high voltage overhead transmission systems is a key element in electricity infrastructure development in any country. With about 45% of the homes in Sri Lanka yet to be electrified and the high demand growth in the areas already electrified, we will invariably have many electricity system development projects in our national electricity network in the near future. Construction of long lengths of high and medium voltage transmission lines and a large number of grid substations will be an integral part of this development process. The development of local expertise in this field of design, manufacturing and construction of high voltage transmission lines and related electricity transmission and distribution systems and the turnkey construction of these projects, entirely by Sri Lankan Companies in recent years, have become a great advantage to the power sector of the nation. Maximizing similar local inputs into power sector development activities need to be encouraged by the authorities in order to reduce costs and keep electricity prices down
