L&T has been executing power transmission projects for more than two decades and offers end-to-end services from design and construction to commissioning of EHV power transmission lines.

Testing

L&T’s Transmission Line Research and Testing Centre (TLRTC) at Kancheepuram, near Chennai is India’s largest tower testing station. Acclaimed as one of the best in the world, this testing station is equipped with facilities to carry out tests on square or rectangular base lattice tower, monopole, tubular structure and guyed tower for capacities up to 1200 kV. This testing bed apart from analysing the accuracy of the assumptions made in the design calculation ensures that the tower members meet the optimum levels and desired performance criteria. This facility is incorporated with the specially designed data acquisition and control system and latest equipment to support the operation. It also has an exclusive proto fabrication and assembly unit which interfaces between design and testing process.

Manufacturing

Backed by its ISO and OHSAS certificated 1,00,000 tpa tower manufacturing facilities in Puducherry and Pithambur, L&T offers complete transmission line implementation solutions. Both the plants are equipped with the latest CNC line for fabrication of towers and microprocessor based temperature controlled eco-friendly systems for galvanisation of tower members.

Construction

The hallmark of L&T’s success lies in its ability to deliver high quality products and services with stringent time schedules and safety conforming to international standards. L&T has executed projects up to 765 kV EHV AC and 800 kV HVDC running through mountains, deserts, forests, rivers and plains to evacuate power from remote power generation centres to load centres. Scope of work offered include sourcing, selection, inspection and supply of line materials including conductors, insulators, hardware, OPGW /EW, construction of transmission lines including foundation, tower erection, stringing, testing and commissioning.
