The transformer incorporates a copper-wound core and heavy-duty cooling fins, ensuring efficient power transmission in extreme temperatures (-40°C to +60°C). With a high short-circuit withstand capacity and IP66 protection, it reliably powers mining equipment, ventilation systems, and processing plants in challenging environments.
Extreme Environment Resistance: Sea Grey anti-corrosive coating and sealed bushings protect against salt, sulfur dioxide, and abrasive dust common in mining sites.
High Voltage Capability: Rated for 35kV input/output, ideal for long-distance power transmission in large mining complexes.
Enhanced Mechanical Strength: Thickened steel tank and shock-absorbing mounts reduce damage from seismic activity and heavy machinery vibrations.
Advanced Cooling System: Optimized fin geometry and low-viscosity oil ensure rapid heat dissipation during continuous high-load operation.
Explosion-Proof Design: Optional flameproof enclosures available for use in gas-rich underground mines (ATEX/IECEx certified).
Underground Mines: Powers conveyor belts, pumps, and lighting systems in deep shafts with high humidity and dust levels.
Open-Pit Mining: Supports large excavators, crushers, and processing equipment in outdoor environments with high UV and temperature fluctuations.
Quarry Operations: Reliably distributes power to drilling rigs and loaders in abrasive stone-handling environments.
Marine Ports: Suitable for coastal mining terminals, resisting salt corrosion from sea air and occasional water splashes.
Q: What is the IP rating of these transformers?
A: Standard models have IP66 (dust-tight and water jet-proof); custom IP68 (submersible) versions available for flooded mine applications.
Q: How often does the oil need to be replaced?
A: Regular oil testing is recommended every 2 years; replacement intervals depend on contamination levels, typically 10-15 years under normal conditions.
Q: Can they be used with variable frequency drives?
A: Yes, designed to handle harmonic distortions from VFDs, with additional surge protection available as an option.
