Step up your power infrastructure with the H59 3 Phase Step Up Power Transformer, engineered to convert low voltage (415V) into high voltage (11kV) efficiently and safely. Designed for modern industrial and utility-scale operations, this oil-immersed transformer offers robust insulation, stable performance under varying environmental conditions, and long service life.
A step-up transformer increases voltage from a lower to a higher level—critical for power transmission over long distances. The H59 3 phase transformer transforms 415V to 11kV, minimizing energy loss in the transmission process. It is ideal for grid interfacing, renewable energy systems, manufacturing plants, and rural distribution networks.

Product Construction
Iron Core:
The core is constructed from cold-rolled grain-oriented silicon steel sheets with high magnetic permeability. Losses are minimized through careful lamination and clamping techniques.
Windings:
Multi-layered cylindrical copper windings provide uniform ampere-turn distribution and high short-circuit resistance. The windings are vacuum-dried and oil-impregnated for superior insulation.
Oil Tank:
Made from welded steel with corrugated panels that allow for thermal expansion without a conservator tank. This design improves heat dissipation and reduces overall transformer height.
- Excellent heat resistance and thermal dissipation.
- Moisture-proof and sealed construction.
- Equipped with gas relay, pressure relief device, and over-temperature alarm.
- Vacuum oil filling prevents oxidation and prolongs oil life.
Operating Conditions
