Three phase core-type transformer

GTS Elettrotecnica’s three-phase core-type transformers offer an advanced and highly reliable technical solution, specifically developed for industrial and commercial applications requiring high power ratings ranging from 40kVA to 1200kVA.

These transformers are characterized by their unique construction, in which the concentric primary and secondary windings are directly wound on the magnetic core of the columns. The entire structure, consisting of columns and heads, is carefully locked in place using sturdy metal plates and tie rods and vacuum impregnated with epoxy resin (VPI – Vacuum Pressure Impregnation technology). This treatment is followed by a thermal polymerization phase in an oven, which permanently consolidates the structure and guarantees the necessary insulation class, ensuring maximum stability, strength, and operational life.

Particular attention is paid to defining the connection between the primary and secondary winding phases, as well as to managing the required angular phase shift between the input and output voltages, allowing perfect adaptability to the specific requirements of each system. This configuration makes it possible to respond effectively to the specific technical requirements of each system, optimizing efficiency and energy performance.

Design flexibility is another key feature of these three-phase transformers from GTS Elettrotecnica. Each model can be fully customized in terms of input and output voltages, physical dimensions, installation methods, and selection of optional accessories, satisfying specific customer requirements with targeted, high-performance solutions.

Thanks to the high quality of the materials, the precision of the construction techniques, and compliance with the most stringent international standards, GTS Elettrotecnica’s three-phase core transformers are the ideal choice for those looking for reliable, safe products that guarantee excellent performance even in the most demanding operating conditions.
