The facility is built in 11.000m² and divided in three well differentiated areas:

Metal Shop: Area where tanks, expansion tanks, and yoke presses, for both power and distribution transformers are manufactured. These are manufactured using steel type SAE 1010.

Conductors Shop: Copper conductors used for both power and distribution transformers are manufactured. The manufacturing process includes the casting and drawing of copper wire, its heat treatment and stripping, where the conductor is covered with several layers of insulation paper known as "kraft paper" characterized by its high dielectric strength and aging resistance. The most appropriate conductor is selected after considering the voltage and power of the transformer. When required the continuously transposed conductor (CTC) is used. This is composed of several wires individually covered with enamel and this entire wire unit is covered with several layers of insulation material.

Distribution Transformers Unit: Area where the core assembly, winding manufacture, and final assembly and testing of all distribution transformers takes place. For the winding manufacture the company owns five low voltage and five high voltage winding machines.
