Benefits of Our 800kVA Transformer
OMEK’s transformator 800kVA not only owns a large capacity, but also achieves a good balance between power efficiency and power distribution reliability.
The 800 kVA capacity can power a significant amount of motor loads, air conditioning systems, lighting, and general production equipment. Thereby, it helps to avoid prolonged full-load operation of the transformer.
Three-phase output provides higher work efficiency compared to single-phase power. Under the same fuel and consumable conditions, it delivers more electrical energy with more balanced power distribution. Equipment like motors can run more efficiently with greater power.
The 800 kVA rating is a popular specification. Therefore, the relative supporting products, such as high-voltage switchgear, low-voltage distribution cabinet and accessories can be easily located on the market. This ensures convenient maintenance and replacement in the future. Thus, it needs relatively lower repair costs.

FAQs
Have any questions? We’re here to help you out.
OMEK’s standard 800kVA transformer is configured with off-circuit tap-changer (±2×2.5%). It is only allowed to adjust when the 800kVA transformer is de-energized. Full load or live operation is strictly prohibited.
If you require 800kVA transformer regulation at full load, select an on-load tap changer (OLTC), which can meet continuous voltage regulation under full load operation.
The above two configurations allow ±5% voltage regulation. When your grid voltage fluctuation reaches ‑15%~+15%, only a step voltage regulator can help.
OMEK Power offers stand‑alone 800 kVA transformer unit, and we also can do compact kiosk substation to include 800 kVA transformer with MV switchgear and LV panels inside enclosure.
| Stand‑alone 800 kVA Transformer | Pad‑mount / Compact Kiosk Substation |
|---|---|
| Only transformer unit, no built‑in HV/LV switchgear | Transformer unit + HV & LV switchgear fully integrated inside metal enclosure |
| Need separate HV/LV switchgears | Install outdoors directly on concrete pad, no dedicated substation room required |
| Replace your old substation transformer equipment | Ideal for construction sites, residential areas, solar PV projects, plug‑and‑play |
