1000kva KNAN Oil Immersed Power Distribution Transformer

07-01 2025 | By:

(Mineral) Oil Natural Air Natural (ONAN) – The core and coils are cooled by surrounding in oil. Heat transfer of oil by natural air convection.
(Non-Mineral) Oil Natural Air Natural (KNAN) – The core and coils are cooled by surrounding in synthetic oil. Heat transfer of oil by natural air convection.

The cooling ways of the oil immersed transformers depend on the fire point of the oil being used in the transformer. Mineral oils are symbolized with “O” since their fire point is below 300°C. Non-mineral oils such as silicone oil, Synthetic Esterand Natural Ester (vegetable oils) are designated with “K” since their fire point is above 300°C.

Non-mineral oils are more expensive but they have different advantages based on the application area of the transformers asked. Non-mineral oils can be devided into two types: synthetic ones and natural ones. Both have higher flashing points and thus are more safe to use in explosive areas defined as Zone 1 and Zone 2.
