French engineering firm Alstom has successfully manufactured and delivered India’s first 800KV high-voltage direct current (HVDC) power transformer for the Champa-Kurukshetra ultra-high-voltage direct current (UHVDC) phase one link.
The project aims to develop an ‘energy superhighway’ of efficient power transmission and connect central India’s power station near Champa to northern India’s Kurukshetra via a 1,365km transmission line.
Under the project, Alstom will build nine power transformers at its largest manufacturing and testing facility in the country.
This latest delivery is the first of nine transformers the company is building. The unit is 13m-long, 5.1m-wide and weighs 310t.
Alstom grid power electronics and automation senior vice-president Patrick Plas said: "These massive transformers will substantially improve grid connectivity by seamlessly transferring power across five electrical regions of India.
"Alstom has been a key player in HVDC for over 50 years and the company is currently executing two 800KV UHVDC bi-pole projects in India.
"The 800KV HVDC transformers are locally manufactured from Alstom’s world-class facilities and reinforce its leadership in the transformer market."
Under the deal, Alstom will also deliver 32 converter transformers, 24 double Thyristors valves, 400KV / 220KV gas and air-insulated switchgears with substation equipment, including Alstom’s first AIS 800KV high-speed direct current switch.
The project further includes overall project management, studies, design, engineering, training, manufacturing, civil works, site erection, testing and commissioning.
To date, Alstom has delivered more than 40 HVDC projects and has several currently ongoing, such as DolWin3 in Germany, and Rio Madeira in Brazil.
