The FUSHIN 3-phase to 1-phase transformer is a static power conversion device that plays the role of converting industrial 380V current down to residential 220V voltage. Specifically, this device provides a safe energy platform, helping 1-phase machinery operate smoothly in factory environments.
There are many segments of FUSHIN brand 3-phase transformers manufactured from pure copper wire cores to optimize lifespan. Next, these products are far superior to cheap aluminum transformer lines thanks to their extremely durable continuous load-bearing capacity.
FUSHIN's 380V to 220V transformer system brings the perfect solution to support phase balancing and maximally limit dangerous phase unbalance conditions. Furthermore, the electrostatic shielding manufacturing technology helps protect the load system from unwanted short-circuit and fire incidents.

What is a 3-phase to 1-phase 380V to 220V transformer?
A 3-phase to 1-phase 380V to 220V transformer is a static electromagnetic device used to step down voltage from an industrial 3-phase power grid to residential 1-phase voltage. More specifically, the operating principle of the machine is based on electromagnetic induction to change the voltage value while keeping the frequency constant.
This transformer is widely applied in substations, manufacturing workshops, or industrial parks where only a 3-phase 380V power source is available but there is a need to operate a mass of residential 220V equipment. Thanks to the closed magnetic field structure, the device not only steps down the voltage but also creates an electrical isolation barrier, minimizing harmonic interference and protecting sensitive electronic circuits. Continuous operation requires the product to meet extremely high insulation standards, ensuring no electrical leakage to the outer casing causing danger to users.
What do the main structural components of a 3-phase to 1-phase transformer include?
There are 3 main structural components of a 3-phase to 1-phase transformer including the electrical technical steel core, the conductor winding system, and the protective machine casing. To illustrate, each part plays an irreplaceable role in stable energy conversion.
The electrical technical steel core is assembled from many thin silicon steel laminations, coated with insulation to minimize Foucault eddy currents. The conductor winding system includes a primary winding receiving 380V power and a secondary winding outputting 220V power.
-
The most important quantitative factor is using a 100% pure copper wire transformer.
-
Copper wire has low resistivity, helping to reduce thermal energy loss.
-
The machine casing is made from anti-corrosion electrostatically painted steel, accompanied by a system of voltage meters, ammeters, and overload protection circuit breakers.
Is a 3-phase to 1-phase transformer capable of phase balancing and current stabilization?
Yes, a 3-phase to 1-phase transformer is fully capable of phase balancing and current stabilization thanks to the load-sharing mechanism, closed magnetic field structure, and electrostatic shield. Besides, this feature helps factories avoid the risk of reactive power penalties from the power company.
When connecting 1-phase equipment to a normal 3-phase grid, the load will concentrate on one phase causing local overload and unbalancing the entire system. However, when using a 3-phase to 1-phase transformer, the special winding structure allows the device to draw power evenly from all 3 input phases, then synthesize and output a large-capacity 1-phase source. This helps the power grid maintain a perfect state of balance, and the output voltage always remains at a stable 220V regardless of supply source fluctuations.
What popular FUSHIN 380V to 220V transformer lines are there today?
There are 2 main FUSHIN 380V to 220V transformer lines popular on the market: the small capacity transformer line for residential use and the large capacity substation line for industry. Below, we will carefully analyze each type to choose the most optimal investment level.
The small capacity transformer line usually ranges from 3KVA to 15KVA, designed compactly, easy to move and install in family workshops, laboratories, or control cabinets. The large capacity substation line from 20KVA to 100KVA is constructed with an oil heat dissipation system or forced fan cooling, specialized for heavy-duty production lines. This classification criterion is directly based on the power consumption of the load equipment. Choosing the wrong capacity not only wastes budget but can also cause the machine to constantly trip the circuit breaker due to overload.
How does the performance of FUSHIN copper wire transformers compare to regular transformers?
The FUSHIN copper wire transformer excels in the ability to withstand continuous 100% capacity load, while a regular aluminum transformer is only good in terms of initial cheap price. However, considering the long-term operational economic problem, the copper wire transformer is the only correct choice.
The most important criterion to evaluate performance is electrical conductivity and heat generation level. Copper has a resistivity of only about 60% compared to aluminum, so the current passing through the copper wire transformer loses less as thermal energy. This helps the machine run quietly, coolly, and save significant electricity. Conversely, aluminum transformers radiate heat very strongly, easily leading to brittle breakage of the coils after about 2 to 3 years of high-intensity use.
What is the basic difference between a 3-phase to 1-phase transformer and a 1-phase to 3-phase transformer?
The 3-phase to 1-phase transformer excels in the feature of evenly stepping down the 380V industrial source to 220V, while the 1-phase to 3-phase transformer is optimized for the ability to boost the residential 220V source to the 380V industrial standard. Conversely, if applied in the wrong environment, both types of machines are useless.
The biggest distinguishing criterion lies in the direction of voltage transformation and practical application. The 3-phase to 1-phase transformer solves the problem of "excess" high voltage, safely redistributing the current to small equipment. Meanwhile, the 1-phase to 3-phase transformer handles the "shortage" problem, helping small-scale facilities without the conditions to run a 3-phase line still be able to operate large-capacity motors. Confusion between these two types frequently occurs with non-professional users. Customers need to clearly determine how many phase wires the input source has and how many Volts the output equipment voltage requires before making a purchase decision.
Should one use a FUSHIN transformer to thoroughly handle serious phase loss and phase unbalance conditions of the power grid?
Yes, you absolutely should use a FUSHIN transformer to handle power grid phase loss thanks to load-sharing phase balancing technology, precise control components, and absolute protective isolation capabilities. Especially, this is the most urgent asset protection solution for expensive automation systems.
Phase unbalance occurs when the load on the 3 phases is uneven, leading to high-phase and low-phase voltages, causing motor fires and explosions. The FUSHIN brand 3-phase transformer is manufactured with a flexible compensating magnetic flux system. When the power grid encounters a 1-phase loss or local voltage drop incident, the machine will automatically regulate the surplus current from the remaining phases to compensate, ensuring the 220V output voltage is not interrupted. The device acts as a giant buffer, absorbing all abnormal electrical surges before they spread to the machinery.
In what niche cases are 1-phase to 3-phase transformers mandatory to use?
There are 2 niche cases mandating the use of a 1-phase to 3-phase transformer: mini carpentry workshops that cannot pull a 380V grid line and laboratories that need to test basic 3-phase motor equipment. In addition, this equipment also assists auto garages in operating car lifts.
The 1-phase to 3-phase transformer (also known as a power booster) completely solves infrastructure difficulties.
-
Small-scale processing workshops are often located in residential areas, where the power company does not permit pulling a 380V line.
-
The machine helps operate lathes and CNC machines running on 3-phase motors smoothly, protecting the rotating shaft from jerking.
