Three-phase power transformers immersed in insulating oil (mineral or vegetable) are used in power and electrical energy distribution substations, both in sheltered locations and outdoor installations.
It can be used as a voltage elevator or voltage regulator. They are manufactured in powers above 300 kVA up to 5000 kVA in voltage classes of 7.2 kV, 15 kV, 25 kV and 36 kV.
In photovoltaic energy generation systems, they are used as step-up transformers, adapting the low generation voltages to the levels required for consumption or distribution.
Usual powers of 500, 750, 1000, 1500, 2000, 2500 and 3000 kVA, in classes 15, 24.2 and 36.2 kV. High performance with high yields and converging with the needs and strategies of reducing system losses and energy conservation of each particular customer.
