Features
-
HV and LV windings made of aluminum to minimize the mechanical stresses of overload or short circuit conditions.
-
Windingss encapsulated in epoxy resin under high vacuumto eliminate the presence of micro-bubbles in the insulation.
-
The micro-bubbles are responsible for creating a capacitive effect in isolation that produces partial electrical discharges and compromises the operation and life of the transformer.
-
The encapsulation in epoxy resin under high vacuum guarantees the elimination of partial discharges.
-
Core made from grain-oriented silicon steel sheets and step-lap construction to reduce stray losses and noise level.
-
Final assembly is performed in a controlled environment.
-
Final testing with the issuance of the reports.
-
Encapsulation is available in class F (155 ° C) or class H (180 ° C) insulation.
