30 kVA Single Phase Isolation Transformer, 110V to 220V

Note:

1. The transformer can only convert voltage, and CANNOT convert frequency.
2. The transformer CANNOT convert 1-phase voltage to 3-phase voltage.
3. Support voltage customization, various specifications customization.

Q1. What are the three insulation grades, and how do I choose the right one?

The three available insulation grades correspond to different maximum operating temperature classes, offering increasing levels of thermal tolerance. The appropriate grade depends on your installation environment, ambient temperature, expected load profile, and applicable safety standards. For high-ambient or continuous heavy-duty applications, a higher insulation grade is recommended to ensure long-term reliability. Please consult with our team when specifying your order to select the grade best suited to your requirements.

Q2. What does the 1.2× overload capacity mean in practice?

It means this transformer can safely operate at a load exceeding its rated 30 kVA capacity — specifically, more than 1.2 times that rating (i.e., over 36 kVA) — for a continuous period of up to one hour. This is particularly useful in applications involving motor starting, intermittent peak loads, or temporary demand spikes, where the transformer must handle brief but significant overload conditions without tripping or sustaining damage.
