Product Features
it features AN/AF cooling with integrated fans and temperature
sensors, aluminum windings on a silicon‑steel core with an
electrostatic shield, and an off‑circuit tap changer for stable
voltage regulation. Engineered for low losses and low harmonic
distortion (THDi < 3%), F‑class insulation and controlled
temperature rise ensure robust thermal performance, and compliance
with AS60076/AS3000 standards guarantees reliable, efficient power
distribution in demanding installations.
Performance Characteristic
1)The iron core is made of high-quality silicon steelsheet.The
surface is coated with anti-corrosionand good heat dissipation to
ensure the transformer's low loss and corrosion resistance.
2)The high voltage winding has a continuous drop downdisc with a
strip conductor(alumi num or copper)anddouble layer insula-
tion.Windings are cast undervacuum with epoxy resin.
3)The low-voltage winding is made of aluminum orcopper foil and
wound with insulating foil pre-im-pregnated with epoxy resin.The
coil is cured in anoven to form a very compact winding.
4)The encapsulation process is a key stage withinthe manufacturing
process Encapsulation is car-ried out under the most rigorous
conditions inorder to ensure optimum insulating and mechani-cal
characteristics.
5)In the vacuum casting chamber,the resin is pouredinto the mold to
cure and form a high strength FRPbody structure.
