200 kVA Single-Phase Low-Voltage High-Current Transformer

200 kVA Single-Phase Low-Voltage High-Current Transformer

Capacity and input/output voltage can be customized.

This single-phase high-current dry-type transformer adopts a robust laminated core and high-capacity copper winding structure. The secondary side is equipped with large copper busbars to deliver extremely high output current at low voltage. As a special industrial transformer, it is widely used in resistance welding, metal smelting, electrolysis, industrial heating and other heavy-duty working conditions. The dry-type design eliminates oil leakage risk, featuring stable performance, low noise and easy maintenance. Customization on capacity, voltage ratio and busbar layout is available to meet diverse client requirements.

Operating Conditions

Ambient temperature: ‑5℃ ~ +40℃. Monthly average max ≤ +30℃, yearly average ≤ +20℃. Derate capacity if operating above +40℃.
Altitude: ≤1000 m. Derate for altitude over 1000 m.
Relative humidity: ≤90% at +25℃, no surface condensation.
Installation: Indoor dry location, free of corrosive gas, explosive mixtures and conductive dust.
Environment: No heavy shock or violent vibration.
Operation: Continuous rated duty.
Input supply: Nearly sinusoidal AC waveform, voltage fluctuation ±10% of rated value.
Cooling: Natural air cooling, maintain adequate ventilation clearance.
