About this product
Product information from the supplier.
The Three-Phase 380V to Three-Phase 220V Transformer is a precision-engineered power solution designed to resolve critical voltage adaptation challenges in industrial environments. In many modern power grids, the standard supply is three-phase 380V; however, a vast array of specialized instruments, control modules, lighting systems, and sensitive electronic devices require a steady three-phase 220V supply to function safely and efficiently.
By seamlessly converting high-voltage input into the required lower-voltage output, this transformer eliminates the risk of equipment failure due to overvoltage and ensures a stable startup process. Whether integrated into a large-scale manufacturing line or a localized control center, it provides the necessary electrical foundation for uninterrupted operational continuity and enhanced equipment longevity.

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.
