Transformers Type

Pedestal

Nacional de Transformers - TESLA puts at your disposal the manufacture of oil-immersed transformers with dead front or garden type with a range of powers ranging from about kVA to 3000 kVA, and voltage series up to 34.5 kV, using mineral oil as a cooling medium. or vegetable oil according to the technical requirement. Optimal for underground electrical energy distribution, offering a safer and more modern installation.

They are classified into radial type and mesh (ring), according to the type of circuit specific to each project. Depending on the type, the transformer has one or more disconnectors, protection fuses sensitive to excessive load currents or oil temperature, and current limiting backup fuses; pre-molded type connection terminals and elbow type surge arresters , among other accessories.

The construction of the internal active part is similar to that of transformers in oil both in the manufacture of the core and in that of the low and medium voltage coils; What makes them different is the mechanical construction of the tank, the addition of the protection cabinet and the internal installation of new protection and sectioning elements, making this type of transformer a compact substation.

They are designed with 65 ° C winding temperature rise and top oil temperature 60 ° C or less, winding material: copper / copper , copper / aluminum , aluminum / aluminum , K-factor designs for harmonic control. ( K1 , K2 , K4 , K6 , K9 , K13 , K20 , K30 ), among others.

Transformers suitable to meet the electrical energy requirements in sectors such as:

• Residential buildings

• Urbanizations

• Malls

• Hospitals

• Education centers (colleges, universities
