The 3-phase bare transformer 380V to 220V is a specialized static electromagnetic device for stepping down industrial currents, featuring a casing-free design for direct integration into control cabinet systems. Following this, the use of a bare transformer not only maximizes the saving of assembly space but also accelerates the natural convection heat dissipation process, ensuring safety for the entire electromechanical system.
There are 4 main capacity ranges of the FUSHIN 380V/220V transformer categorized from light load to super heavy load based on the kVA rating criteria. Specifically, this clear classification helps electrical engineers easily choose the right equipment for each factory scale. Besides, the diverse power levels also perfectly meet the strict requirements of CNC machines, milling machines, or automation equipment directly imported from Japan and the US.
The bare transformer wins in optimizing electrical cabinet space, while the model with a protective casing excels in resistance to mechanical impacts from the external environment. In short, the choice between these two product lines depends entirely on the actual installation location of the factory. In particular, to thoroughly solve complex technical problems, the custom transformer manufacturing service of FUSHIN will provide the most suitable power supply solution for all specific needs.
What is a 3-phase bare transformer 380V to 220V?
The 3-phase bare transformer 380V to 220V is an industrial step-down device belonging to the FUSHIN brand, standing out with a completely unshielded casing design to maximize natural heat dissipation capabilities.
Regarding the question of what a 3-phase bare transformer 380V to 220V is, more specifically, this device brings many outstanding advantages during electromechanical construction and assembly.
The outstanding feature of this machine series lies in its ability to accurately and stably step down the standard 3-phase 380V grid power to the standard 3-phase 220V level. The product possesses extremely solid foundational attributes including a premium oriented silicon steel magnetic core, a pure copper winding system, and safe insulated base stands. The main use of the device is to provide a standard power supply for fully imported industrial equipment systems. Furthermore, the complete removal of the outer casing helps electrical cabinet manufacturers easily arrange components and route cables within strictly size-limited spaces.
How are the capacity ranges of FUSHIN 380V/220V transformers categorized?
There are 4 main groups of FUSHIN 380V/220V transformer capacity ranges: small capacity, mid-range, large capacity, and super heavy load according to the actual kVA capacity rating criteria.
Revolving around how the capacity ranges of FUSHIN 380V/220V transformers are categorized, next we will delve into the technical specifications to optimize operational efficiency.
Operational note: To optimize efficiency, when selecting large capacity and super heavy load groups, it is necessary to pre-calculate the heat dissipation space, the load-bearing capacity of the installation site, and design the protective electrical cabinet corresponding to the equipment size. Are you needing to optimize a transformer station for a specific project?
This classification criterion is strictly determined by the actual load demands of modern manufacturing plants. Specifically, the small capacity group (from 1kVA to 15kVA) typically serves local control cabinets of individual machines. The mid-range group (from 20kVA to 45kVA) is an ideal choice for small-scale production lines. The large capacity group (from 50kVA to 100kVA) is specialized for central workshop clusters, and the super heavy load group (over 120kVA) robustly meets the needs of internal step-down substations. The clear quantitative factors from these capacity ranges help electrical engineers accurately calculate wire cross-sections, absolutely preventing overcurrent or sudden voltage drop phenomena.
Which industrial machinery lines are required to use a 3-phase 220V transformer?
There are 3 main groups of industrial machinery required to use a 3-phase 220V power source: precision mechanical processing machines, plastic injection molding machines, and automation equipment according to the national power grid standards of the manufacturing country.
Revolving around which industrial machinery lines are required to use a 3-phase 220V transformer, more specifically, this is an indispensable solution for imported equipment.
The classification criteria for these machine lines are mainly based on their import origins from Japan, the US, or Taiwan, where the 3-phase 220V voltage standard is a mandatory regulation. Mechanical processing machines like CNC milling machines and lathes need a standard power source for their motherboards to operate accurately. Plastic injection molding machines require a stable supply to maintain their heating bars, while automation equipment needs to synchronize its servo motor systems. Practical quantitative factors show that supplying the correct original voltage helps machines increase their motor durability to the highest level, minimizing maintenance costs.
Can bare 3-phase transformers be installed directly outdoors?
You should not install bare 3-phase transformers directly outdoors because the IP00 design is not waterproof, which can easily cause dangerous short circuits and rapidly oxidize the silicon steel core.
Regarding the issue of whether a bare 3-phase transformer can be installed directly outdoors, you nevertheless need to firmly grasp the technical standards concerning the machine's operating environment.
The most important reason is the IP00 protection rating of the bare machine series, which has absolutely no casing to shield it from adverse weather impacts. In more detail, when in direct contact with rainwater or high moisture fog, the insulation layer between the windings will break down, leading to the risk of electrical leakage and short-circuiting the entire system. Besides, the oxidation of the silicon steel core due to moisture will increase Foucault currents, causing massive power loss and severely shortening the lifespan of the step-down device.
What is the difference between a bare 3-phase transformer and a model with a protective casing?
The bare transformer wins in the criterion of optimizing electrical cabinet space, while the model with a protective casing excels in the criterion of withstanding impacts from the external environment.
Discussing what the difference is between a bare 3-phase transformer and a model with a protective casing, in short, each version is designed to serve a completely distinct application context.
The most important criterion for comparing these two product lines is the installation location and heat dissipation method. The bare type has an absolute competitive advantage as it helps save up to 30% of the space inside main control cabinets, reducing cabinet manufacturing costs for contractors. Conversely, the transformer series with a protective casing (usually IP20 standard or higher) is mandatory for independently placed transformer stations, areas with high metal dust density, or places where there is a risk of direct physical impact on the equipment.

How do the silicon steel core structure and insulation class affect the durability of FUSHIN transformers?
The oriented silicon steel core structure is the core component of FUSHIN transformers, notable for its ability to eliminate magnetic flux loss and maintain the stability of the windings.
Explaining how the silicon steel core structure and insulation class affect the durability of FUSHIN transformers, more specifically, this is the key factor determining the product's lifespan.
The prominent feature is that the silicon steel sheets are cut and assembled with absolute tightness, synchronously combined with a premium high heat-resistant insulating varnish layer. This technical attribute helps eliminate adverse heat-generating Foucault currents throughout the process when the machine has to work at high intensity. The main use of this material combination is to keep the transformer block always at a safe temperature level, thoroughly preventing internal short-circuit incidents, thereby extending the equipment's lifespan up to decades.
