Product Q&A
Q:What is the capacity range of this oil-immersed distribution transformer?
A:
We can supply from 10 kVA to 2500 kVA, covering single-phase and three-phase types. Customized capacities are also available upon request.
Q:Is this transformer fully sealed or with a conservator tank?
A:
Both designs are available. The model shown uses a conservator tank for oil level stabilization. We also produce fully sealed types for specific applications.
Q:What are the no-load loss and load loss levels?
A:
Our transformers are designed to meet international energy efficiency standards (such as IEC 60076 and local IE2/IE3 equivalents). Exact loss values depend on capacity and voltage class please contact us for the detailed technical datasheet.
Q:Do you provide tap changing?
A:
Yes. We offer both off-circuit tap changer (manual, de-energized) and on-load tap changer (OLTC) options, depending on your requirements.
Q:What cooling method does this transformer use?
A:
It uses oil natural air natural (ONAN) cooling. The corrugated tank design increases the heat dissipation area for reliable continuous operation.
