Product type
Oil immersed transformers are electrical devices that transfer electrical energy between two or more circuits through electromagnetic induction. They are filled with insulating oil, which helps in cooling and provides electrical insulation. The oil also serves to protect the internal components from moisture and contaminants. These transformers are typically used in power distribution systems to step up or step down voltage levels efficiently.
| Cooling method | Oil-immersed |
| Voltage rating | Up to 765 kV |
| Frequency | 50 Hz or 60 Hz |
| Power rating | From 10 MVA to over 1000 MVA |
| Insulation class | Class A to Class H |
| Protection level | IP20 to IP67 |
When selecting an oil immersed transformer, buyers should consider the required voltage and power ratings based on their application. It's important to specify the cooling method, insulation class, and any environmental factors that may affect performance. Certifications such as ISO or ANSI may be relevant, depending on regional standards. Additionally, buyers should determine the quantity needed for their project to ensure cost-effectiveness.
