Oil type transformers are designed to operate at high altitudes by taking into account the effects of reduced air pressure and reduced cooling capacity. This is achieved by increasing the size of the transformer’s core and windings, as well as by using a higher grade of insulation. Additionally, the oil used in the transformer must be able to withstand the lower air pressure and higher temperatures that occur at higher altitudes.
Compared to Dry type transformers, Oil type transformers are better suited for high altitude operation due to their increased cooling capacity. The oil used in Oil type transformers is able to absorb more heat than air, allowing the transformer to operate at higher temperatures without overheating. Additionally, the oil is able to circulate more efficiently, allowing for better cooling of the transformer’s components.

Oil type transformers are also designed to be more resistant to the effects of reduced air pressure. The transformer’s core and windings are designed to be larger and more robust, allowing them to withstand the increased stress caused by the lower air pressure. Additionally, the insulation used in the transformer must be able to withstand the higher temperatures and lower air pressure that occur at higher altitudes.
Overall, Oil type transformers are designed to operate at high altitudes by taking into account the effects of reduced air pressure and reduced cooling capacity. By increasing the size of the transformer’s core and windings, as well as by using a higher grade of insulation, Oil type transformers are able to withstand the higher temperatures and lower air pressure that occur at higher altitudes.
