Hyderabad metro to get aerial power line
Hyderabad- The Hyderabad metro rail project will soon have aerial 25 KV power line across 72-km viaduct. This line will be constructed in three corridors.
The concerned authorities initially thought to go for prevalent trend in Europe of having power line between tracks. But later on discussions with experts and studying the power systems of some existing metro lines this plan was rejected.
The Managing Director of Hyderabad Metro Rail (HMR) assured that they will try to compensate for the overhead traction line with improved design. AP Transco is assigned to supply uninterrupted power to railway traction and also stations and depots. The project requires total amount of 75 MW of power a day. And AP Transco will supply 130 KV power, which will be scaled to 25 KV for the traction and 35 KV for stations and depots.
There will be four new key substations for this project which includes Uppal, Miyapur, Yousufguda and Mahatma Gandhi Bus Station (MGBS) Imliban. The Upaal and Miyapur are the two main power receiving stations which will cover five acres of land. The construction of Uppal site is almost finished while the work on Miyapur substation is expected to begin soon.
Both Mahatma Gandhi Bus Station (MGBS) and Yousufguda substations will cover one acre of land. Work at Yousufguda substation is all set to begin while land at MGBS is yet to be delineated. Free land has been given to AP Transco to construct all the facilities. It is estimated that the design of power system will serve to draw power continuously from any of the three corridors in case of any problem on a particular stretch or corridor.
