During the process of serving multiple UAE transformer customers, JACK, the sales director of Hengfengyou Electric, found that the UAE power grid mainly operates in 380kV, 220kV, and 132kV substations, and transmits electricity to various cities and regions through transmission lines. Therefore, the transformers used in the United Arab Emirates are mainly designed for these voltage levels. At the same time, there are also a small number of 66 kV and 11 kV substations and distribution stations.



The main types of transformers used in the United Arab Emirates are dry-type transformers and oil-immersed transformers, with oil-immersed transformers being the most widely used type. This is because oil-immersed transformers have advantages such as high durability and reliability, strong temperature control ability, and are suitable for the hot climate and high load power system needs of the United Arab Emirates. At the same time, in some special occasions, such as explosion-proof areas and high-altitude areas, dry type transformers are also widely used.



The reasons why oil immersed transformers are particularly widely used in the United Arab Emirates are as follows:



Climate conditions: The climate in the United Arab Emirates is extremely dry and the temperature is relatively high, which can lead to aging of circuit boards and wires and shorten their service life. Oil immersed transformers can effectively dissipate heat and protect circuit boards and wires by circulating insulation oil, thus adapting to this climate condition.



Energy demand: The United Arab Emirates is one of the largest energy producers in the world, with abundant oil and natural gas resources. Due to the high demand for energy, the UAE government tends to use oil immersed transformers with lower costs.



Maintenance cost: compared with dry type transformer, the maintenance cost of oil immersed transformer is lower. Due to the recyclability of insulation oil, oil-immersed transformers can save on usage costs and make it easier for maintenance personnel to inspect and repair equipment.



Safety: Although oil is used as the insulation medium for oil-immersed transformers, this oil is specially made, non flammable, and not explosive. The equipment itself is also designed with various safety protection devices, such as oil spill holes, fire prevention devices, etc. Therefore, the safety performance of oil-immersed transformers is also guaranteed.



Mature technology: compared with other types of transformers, oil immersed transformers have developed more maturely. Therefore, in the power industry of the United Arab Emirates, oil-immersed transformers are widely used in the power system.



Hengfengyou Group has rich experience in customized production of transformers, and its products are exported to more than ten countries around the world. Currently, they operate well and have reliable quality, proving the high reliability of Hengfengyou transformers（ hfy@hengfengyou.com ）。 Oil immersed transformers are widely used in the United Arab Emirates, closely related to factors such as climate conditions, energy demand, maintenance costs, safety, and the maturity of Hengfengyou Electric technology.



In the United Arab Emirates, oil immersed transformers are mainly used in the following fields:



1. Power system: Oil immersed transformers are the most common type of transformer in the power system, used to convert the voltage level of electrical energy to meet the power needs of different regions.



2. Industry: Oil immersed transformers are also widely used in the industrial field. For the operation of some machines and equipment, the voltage demand may be higher than that of ordinary household power systems, and low-voltage power sources cannot meet these needs.



3. Architecture: In the construction of large buildings, oil immersed transformers help provide stable power supply to ensure the normal operation and safety of the building.

4. Community: Oil immersed transformers are also used to distribute electricity in cities and communities to ensure stable voltage and power demand in each area.
