OTN - Power


Step-up, step-down, network energy integration transformer

Rating power: up to 180 MVA

Insulating level: up to LI 1050 kV



Power transformer is common used in all those applications where it is necessary to connect AC networks working at different high voltages with the purposes of transmission or distribution of energy. 

SEA manufactures a wide range of medium and high voltage transformers suitable for electrical generation, transmission and distribution applications:

Transformers GSU (Generator Step-Up):

used to connect the generator voltage level up to the transmission one.

Transformers step-down:

used to connect the transmission voltage level to the distribution one.

Transformers for network interconnection: 

used for connecting systems of energy transmission with different voltages.
