Frequently Asked Questions
Its primary purpose is to step down three-phase 380V power from the grid to three-phase 220V, allowing equipment designed for lower voltages to operate safely without risk of damage.
Yes, we offer both indoor air-cooled models and outdoor oil-immersed versions with protective enclosures to withstand various environmental conditions.
You should calculate the total power consumption (Watts) of all connected 220V devices and add a safety margin of 20-30% to avoid overloading the transformer.
Yes, our transformers are engineered to be compatible with both 50Hz and 60Hz global power standards, ensuring versatility across different regions.
We use high-purity electrolytic copper for the windings, which minimizes internal resistance and maximizes electrical efficiency compared to aluminum alternatives.
Due to the high voltage involved (380V), installation must be performed by a certified electrician to ensure compliance with local safety codes and proper grounding.
