An Executive Analysis of Power Infrastructure Requirements in Orkhon Province, Mongolia
Erdenet, located in northern Mongolia's Orkhon Province, stands as one of the world's most significant centers for heavy copper and molybdenum mining and pyrometallurgical processing. At the heart of this industrial cluster is the Erdenet Mining Corporation (EMC), which operates massive open-pit mining complexes, froth flotation concentrators, and hydrometallurgical electrowinning plants. These industrial operations consume immense quantities of continuous Direct Current (DC) power. Converting grid-supplied High Voltage Alternating Current (HVAC) into clean, ultra-stable, high-amperage Direct Current requires rectifier transformers designed to withstand extraordinary electromechanical, thermal, and electrical stresses.
To overcome the intense industrial constraints of Erdenet, Zhejiang Tanaka Electric Co., Ltd. supplies advanced multi-pulse rectifier transformers built upon specialized magnetic phase-shifting architectures. By utilizing extended delta, star, and zig-zag secondary vector configurations (such as Dd0y11, Dy11d0, or multi-winding fission designs), our transformers achieve precise electrical phase shifts of 30°, 15°, or 7.5°. This effectively multiplies the effective pulse number to 12-pulse, 24-pulse, or 48-pulse systems.
Higher pulse numbers cancel out harmonic currents on the primary HVAC side, eliminating the need for expensive, high-maintenance active filter banks. Furthermore, our transformer designs incorporate extra-low loss Cold-Rolled Grain-Oriented (CRGO) silicon steel cores (M0H/M1H grade) and 99.99% oxygen-free copper conductors insulated with thermally upgraded Nomex paper, guaranteeing maximum efficiency under continuous full-load duty (S1 duty cycle).

Turnkey Transformer Engineering Solutions Designed for Mongolian Industrial Logistics
In hydrometallurgical processing plants across Orkhon Province, our oil-immersed rectifier transformers are coupled with high-power thyristor bridge assemblies. They convert 35kV medium-voltage utility power down to precise low-voltage (0V to 3.3kV), high-current DC output (up to 100kA). Featuring multi-winding step-down secondary outputs, these systems provide exceptionally smooth DC current necessary for cathode copper deposition without thermal overload.
As Mongolia transitions toward green mining energy initiatives, Tanaka provides specialized hydrogen production rectifier transformers. These units seamlessly handle dynamic load fluctuations caused by solar and wind power inputs, providing continuous DC power to alkaline (ALK) and proton exchange membrane (PEM) electrolyzers in extreme cold climates.
For industrial foundries in Erdenet and Darkhan, our furnace transformers feature reinforced magnetic cores designed to withstand severe electrical arc strikes, sudden short-circuit impacts, and cyclic thermal shock without structural degradation or insulation loss.
Providing DC traction power conversion for heavy haul mineral transport rail lines running between Erdenet, Ulaanbaatar, and border dry ports. Designed with hermetic oil sealing and synthetic ester fluids rated for -50°C freezing conditions.
Shipping massive industrial equipment into landlocked Mongolia requires seamless logistics planning. Zhejiang Tanaka Electric maintains established heavy-freight transport routes originating from our Zhejiang manufacturing hub directly into northern Mongolia via the Erenhot – Zamiin-Uud border freight rail corridor.
