Frequently Asked Questions

Q: What is the primary purpose of a 380V to 220V transformer?

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.

Q: Can this transformer be used for both indoor and outdoor installations?

Yes, we offer both indoor air-cooled models and outdoor oil-immersed versions with protective enclosures to withstand various environmental conditions.

Q: How do I determine the correct kVA capacity for my needs?

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.

Q: Does it support different frequencies like 50Hz and 60Hz?

Yes, our transformers are engineered to be compatible with both 50Hz and 60Hz global power standards, ensuring versatility across different regions.

Q: What materials are used in the windings to ensure efficiency?

We use high-purity electrolytic copper for the windings, which minimizes internal resistance and maximizes electrical efficiency compared to aluminum alternatives.

Q: Is professional installation required for this equipment?

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.
