Toshiba Transmission & Distribution Systems (India) Pvt Ltd (TTDI) has announced the winning of a major order involving the supply of gas-insulated switchgear (GIS) to be installed at open-air substations in Goa and Andhra Pradesh.
In a release, TTDI said that it has received orders for 23 units of 400kV and 9 units of 220kV GIS to the new 2x500MVA substation at Xeldem in Goa, and for pooling substations of solar and wind renewable projects at Alamuru and Kodamuru (both in Andhra Pradesh).
These GIS units will be manufactured at TTDI’s state-of-the-art facility near Hyderabad and the delivery to the site locations will start in May this year. These units will be installed outdoors in open-air environment.
High reliability
Speaking at this occasion, Mr. Hiroshi Furuta, Chairman & Managing Director, TTDI said, “TTDI’s advanced technology & processes, high-level background integration, state-of-the-art manufacturing facilities, massive production capacity, and a highly skilled workforce yield high-quality GIS that is Made-in-India. Toshiba GIS requires far less space and is resistant to the damages caused by salty environments, sand dust storms, and humid atmospheres. The performance of GIS under these severe conditions offers high reliability.”
Reduced construction cost
“The outdoor open-air type GIS need not be placed in the building, thereby reducing the construction cost and time of the building in addition to improving the construction quality and safety, which in turn reduces the construction cost of the project as a whole. GIS usage is widespread in Japan and Toshiba has expertise in excellent gas sealing technologies. We are delighted to receive these orders and are committed to actively contribute to the development of transmission and distribution networks and the introduction of green energy in India FOR A NEW DAY,” the CMD added.
The GIS advantage
Compared to air-insulated switchgear (AIS), GIS can reduce installation space and is used in areas where it is difficult to secure land for large substations, such as crowded urban areas and coastal areas where deterioration of insulation is expected. In particular, the outdoor open-air GIS does not need to build a GIS building, making it possible to increase the number of GIS substations in a short period of time as the transmission and distribution network is developed and strengthened. Also, the outdoor open-air GIS brings the full value of the GIS technology which supports early capitalization and return on revenue and alleviates challenges due to land shortages, remote and strategic locations, and other harsh environmental conditions. In addition, the outdoor GIS technology wherever applied mitigates risks of cost and time overruns, in addition to alleviating safety risks.

Over 40 units supplied
Toshiba has traditionally manufactured outdoor GIS with features that can withstand harsh external environments. Since 2017, TTDI has been manufacturing several types of GIS covering voltages like 400kV, 220kV, 132kV, and 66kV. TTDI has so far received orders for more than 40 units of outdoor GIS, TTDI said.
