In our Project Kylarevägen article series, we have covered the entire process, from casting and assembly to final delivery.
Tekniska Verken in Linköping, one of our framework agreement customers, submitted a request that extended beyond our existing contract. With a strong focus on charging infrastructure, they are developing a charging site in central Linköping for both electric cars and heavy-duty electric trucks. This required a power grid substation with a capacity exceeding 3 MVA. After evaluating different options, Tekniska Verken selected our cost-efficient solution, the TSB3E – our largest indoor-serviced concrete station. The standard configuration houses three transformers of up to 1250 kVA each.
The production process began with concrete casting, the first crucial step in manufacturing the substation. This was carried out by experienced professionals, following a carefully planned procedure. Next, the station was assembled and equipped with our compact switchgear unerRING, configured with three transformer compartments and two line compartments.
After testing and quality control, we invited our customers to gain a closer insight into the manufacturing process and discuss any final adjustments.
On Monday, March 11, the final step was taken as the station was transported to its destination in Linköping.
Currently, two of the three transformers will run at nearly full capacity due to the new connections. The third transformer compartment will temporarily house a smaller transformer for the existing connections. However, the station is future-proofed, allowing the smaller transformer to be replaced when higher power demands arise.
