DSubstation - Cooling of generators,
In order to reinforce the reliability of supply and to increase the capacity, the Norwegian power supplier Statnett extended and renewed its grid in the year 2013 and could increase the mains voltage from 300 to 420 kV. A particular challenge posed the consideration of environmental-relevant criteria. In doing so, old lines were replaced by new ones without the erection of new trails.
The substation in Feda connects the Norwegian with the Dutch power grid and provides for a reliable power supply in both countries.
For the cooling of the generators, thermofin®
delivered nine dry coolers of the series TMDH with a capacity of 280 kW each. Because of increased corrosion requirements, the casings are designed in C4 standard. In order to increase the throwing range, the fans are equipped with streamers.
