- Materials
Built for three-phase power networks, enabling stable delivery of 50 kVA across industrial and commercial systems.
50 kVA Single-Phase Transformer:
Designed for single-phase power supply, delivering the same 50 kVA capacity but for smaller and simpler loads.
50 kVA Oil-immersed Transformer:
For 50 kVA oil-immersed transformer, it can cool down efficiently, so it’s great for outdoor use. It works well in industrial environments where you need stable power all the time.
As to 50kVA dry-type transformer, it is ideal for indoor use. This kind of transformer needs less maintenance and is a safe choice for places where safety is a top priority.
50 kVA Core-type Transformer:
When it comes to 50kVA core-type transformer, the first thing comes to our mind is that it’s more affordable. What’s more, it is capable of working reliably in standard, everyday applications. So it’s a solid choice for basic needs.
50 kVA Shell-type Transformer:
50 kVA shell-type transformer also has its advantages. It’s more efficient and mechanically stronger. Moreover, it’s perfect for tight spaces and heavy-duty work environments.
50 kVA Silicon Steel Transformer:
Great for standard uses. It has a lower upfront cost and gives steady performance.
50 kVA Amorphous Alloy Transformer:
Energy efficiency, lower no-load losses, and eco-friendly operation. So it’s good for the environment while saving you energy costs.

Key Features & Advantages
Stable Voltage PerformanceEquipped with multi-step tap changers (e.g. ± 5 % or ± 2 × 2.5 %) to adjust to local grid voltage fluctuations, ensuring safe and stable voltage delivery to downstream equipment.
High Efficiency & Low LossesOMEK provides Level 1, Level 2 and Level 3 energy efficiency options. The higher the efficiency level, the lower the no-load and load losses. Lower losses help you reduce costs and achieve sustainable development goals.
Built to LastWe are committed to using premium-grade materials in our transformers, ensuring zero compromise on quality. Designed for durability, our transformers boast a service lifespan of up to 25 years even in demanding operating environments.
Strong Against Short CircuitsOur transformers are built to handle short-circuit currents—up to 10-25 times the rated current. Even when that happens, they maintain structural integrity and safety.
Meets Global StandardsAll transformers we make comply with international standards, like ISO, ANSI and CE. You can always trust their safety and reliability, no matter where in the world you use them.
Friendly to the EnvironmentWe use eco-friendly insulation materials and amorphous steel core technology. This cuts down on no-load energy losses, so we can reduce the impact on the environment.
Made Just for YouWe can customize transformers to your needs—like different voltage ratings, cooling methods, and mounting types. We’ll deliver your tailored solution with fast lead times.
Fast DeliveryMost orders are shipped in just 1 week. If you’re in a hurry, we also offer an expedited delivery option for urgent needs.

It’s suitable for supplying power to small- to-medium-sized loads, including:
Small and Medium-Sized Industries
Commercial Buildings
Residential Power Supply
Small Renewable Energy Systems
A 50 kVA transformer can supply up to 50 kilovolt-amperes of load. To put it simply, that’s roughly 40 kW of usable power (it might vary a bit depending on the power factor).
Absolutely. Our 50 kVA transformers come in both oil-immersed and dry-type options. You can choose the one that satisfies your work needs and suits the installation environment.
It depends on the type of your 50 kVA transformer. Oil-immersed transformers are ideal for direct outdoor installation. Dry-type transformers, however, are usually better installed indoors or in a sheltered spot, like a covered area that keeps out wind and rain.
The size of the 50 kVA transformer is related to those things: its rated capacity, number of phases, cooling method, how you install it and so on. Generally speaking, the higher the rated capacity, the bigger and heavier the transformer is. So 50 kva transformer are relatively small in volume. Three-phase transformers are larger than single-phase transformers of the same capacity. Dry-type transformers are usually bigger than oil-immersed transformers with the same rating. Pad-mounted transformers are larger than pole-mounted transformers of the same capacity.
Maximum Temperature: +40℃
Minimum Temperature: -25°C (for outdoor transformers)
Minimum Temperature: -5°C (for indoor transformers)
Of course! If you buy our 50 kVA transformer, we will provide full technical support—including helping you with installation, fixing problems if they come up, and giving advice on maintenance. If you need some on-site to help, we can arrange that too!
