Product type
Oil immersed distribution transformers are electrical devices used to step down voltage levels in power distribution systems. They are filled with insulating oil, which serves both as a coolant and an insulator, allowing for efficient operation and heat dissipation. These transformers are commonly found in substations and industrial applications where they facilitate the safe and reliable distribution of electricity.
| Cooling method | Oil-immersed |
| Power rating | Up to 10 MVA |
| Voltage class | Up to 36 kV |
| Frequency | 50/60 Hz |

When selecting an oil immersed distribution transformer, consider the power rating and voltage class required for your application. It's important to specify the cooling method, as well as any specific insulation class needed for your environment. Additionally, inquire about certifications and standards compliance relevant to your region. Quantities may vary based on project size, so be clear about your needs when requesting a quote.
