  • LV: Class 1,2, 2.5, 5, 8.7, 15, 25 or 34.5kV

  • Application: outdoor or indoor, standard or aggressive environments

  • Protection: IP-00, IP-2X, 3X-IP, IP-4X, 5X or IP-IP-6X.

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.
