On October 18, 2010, Tubos Trans Electric (TTE) dispatched the remaining four 20 MVA / 220 kV single phase transformers that, together with the 41.66 MVA / 220 kV transformer shipped on September 4, will be installed at the San Lorenzo Transformer Station, which will help continue expanding Paraguay's electrical system.

These dispatches completed the purchase orders for 11 transformers issued by the National Bureau of Electricity (ANDE) of the Republic of Paraguay. Therefore, TTE complied with the commitments undertaken with the client and added a new export operation, thus reinforcing its presence in foreign markets.
