The "Transformer Substation Installation" project completed in 2017 as part of the In İstanbul Project significantly contributed to Istanbul's energy infrastructure. The project included the installation of 6 units of 1600kVA dry-type transformers and 1 unit of 1250kVA oil-type transformer, totaling 10,850kVA transformer capacity. Supported by 21 medium voltage (MV) cells and 4,800 meters of MV cable installation, the system was designed integrally with low voltage distribution panels and cable channels. All electrical infrastructure testing and commissioning processes were successfully completed, ensuring the region's reliable and uninterrupted energy supply.
