This is an one phase transformer from our only one 750/400 kV substation. It's weigh dimensions are similar than the last transformer, but it has 1500 MVA power (about 2500 MVA 3 phase power), 750/400 kV and it is about $5-6 million USD.

We have 3 pieces from this transformer, and one backlog.

Across these transformers we receive cheap Russian power. From this substation accross an 1000 km long 750 kV line we can receive more power than from our nuclear power plant, but the nuclear power is the cheapest here. The cooperation system is working, the nuclear power plants are working on full power, the cheap power is good business, to give it to other grids. Our 750 kV line are working on about 12-15 % now, the Polish and Romanian-Bulgarian line working on this rate also, come from Ukraine.

They were built for the "communist help giving" stuff, now they are a good way to make good buisness, and keep contact between the European and Russian grids.
