Alstom displays new gas-insulated substation
Alstom Grid showcased a number of technologies and innovations at the ELECRAMA 2014 - one of the largest trade shows for electrical and electronics industry in Asia. Mr Gregoire Poux-Guillaume, President of Alstom Grid and brand ambassador for ELECRAMA 2014, explained: “The transmission sector in India is rapidly evolving and requires the very latest global technologies to be produced locally. The industry has a lead role to play in driving India’s economy at 9 per cent GDP speed - if not more. In terms of technologies, we all are ready for that great day and the journey to get there is not such a long one. This forum will enable us to embrace the debate and lead us all to achieve a common goal of getting the energy infrastructure ready for India’s next chapter. ”The company displayed a wide spectrum of products, systems and services that improve energy efficiency and productivity at every stage of the energy chain – from generation to end use. In addition to its strong portfolio of automation technologies, Alstom Grid also showcased its latest generation of T155 gas-insulated substation (GIS) designed to meet the future challenges of electrical networks up to 420 kV, 63 kA, 5000/6300A.
The T155 substation, it is told, is 40 per cent more compact than its previous version with a reduced footprint, and is easier to access at ground level, easier to transport and 30 per cent faster to erect. The reduced size is mainly due to the single-chamber circuit-breaker that requires less energy to operate.
