ERS tower installation: Supreme repeats its stellar performance

After the successful erection of the first ever bypass arrangement line by an Indian manufacturer on a high voltage transmission line in Ghaziabad, Supreme achieved yet another feat in Uttar Pradesh.

Construction of a new 400 kV Transmission Line between Atur and Indira Puram, remained suspended since February and was likely to remain idle for more than three months, due to a line crossing over 132 kV Single Circuit Transmission Line between Loni and Mohan Nagar in Uttar Pradesh which required a shut down for 5 to 7 days for unstringing of existing S/C line, followed by stringing of 400 kV Quad-Line, replacing a 132 kV Angled Tower and re-stringing with ACSR conductor near Raja Nagar Extension of Ghaziabad.

To put things in perspective due to this problem of 400 metres, the entire line of 18 kms could not be completed resulting in a massive investment condemned to an indefinite “work in progress status” without getting capitalised. Due to obstruction from 132 kV 5 MW line, power evacuation of 580 MW was getting indefinitely delayed.

Supreme was given an opportunity by UPPTCL to offer a suitable solution, in view of earlier contract executed for a Bypass arrangement between Vaishali and Sahibabad S/C TL.

Supreme’s engineering team conducted a survey and analysis report to install three ERS Towers considering a river, a national highway and flyover crossings for scheduled bypass of four spans.
The project was executed in four days with only a line shutdown of 4 hours on 5th June 2017. It may also be noted that we achieved yet another challenging feat of taking the bypass line and crossing the highway without necessitating the disruption of highway traffic even for a minute and without any shutdown.

The project encountered heavy rain and hailstorm after the execution but no damage was found.

“No heavy machinery or earthmovers were used for the execution of the above, other than for transportation,” Supreme informs.
