Deep analysis of the prospects and trends of three-phase transformers in the African market

A three-phase oil immersed transformer is a power transformer that converts electrical energy from one voltage level to another. It consists of three independent coils and an iron core, each coil usually wrapped around the iron core and then soaked in insulating oil. When electrical energy flows through a transformer from one coil, it generates a magnetic field that is transmitted to another coil and causes changes in the electrical energy output. Three phase oil immersed transformers are widely used in industrial and public utility fields to provide safe and stable power supply.

 

 

 

 

The reasons for using three-phase oil-immersed transformers in Africa are as follows:

 

 

 

1. Large electricity demand: Many parts of Africa lack electricity and require large generators and transformers to meet the electricity demand, while three-phase oil-immersed transformers can provide high voltage and high current output to meet the large electricity demand.

 

 

 

2. High reliability: The climate conditions in Africa are harsh, and sometimes harsh weather and environment may occur. However, three-phase oil-immersed transformers have undergone strict testing and verification, with high reliability and durability, and can operate stably in harsh environments.

 

 

 

3. Low maintenance cost: Oil immersed transformers have lower maintenance costs than dry transformers because they require less inspection, maintenance, and upkeep. This is crucial for regions in Africa that lack professional skills.

 

 

 

4. High safety: three-phase oil-immersed transformers can effectively isolate the high-voltage and low-voltage terminals, reducing the possibility of safety accidents.

 

 

 

5. High economic efficiency: The cost of three-phase oil immersed transformers is generally lower than that of dry type transformers, and their service life is also relatively long, which has advantages in terms of economy.

 

 

 

JACK, Sales Director of Hengfengyou Electric, combined with years of experience in exporting transformers, believes that Nigeria, Egypt, and South Africa are the most commonly used three-phase oil-immersed transformers in African countries.

 

 

 

The main reasons are as follows:

 

 

 

1. High electricity consumption: These countries have a very high demand for electricity, requiring a large amount of electricity supply, so large transformers are needed to meet the demand.

 

 

 

2. Rapid economic development: Nigeria, Egypt, and South Africa are relatively developed countries in Africa, with high levels of industrialization and a need for a large amount of electricity support, thus requiring the use of large transformers.

 

 

3. Traditional equipment: Three-phase oil-immersed transformers are mature equipment that is stable and reliable in use. African countries have been relatively late in the construction of power facilities, so they tend to choose mature equipment.

 

 

 

4. Adaptation to the environment: The three-phase oil-immersed transformer adapts to the complex environmental conditions of African countries, can withstand problems such as high temperature, humidity, and pollution, and has a long service life.

 

 

 

Overall, the main reason why three-phase oil-immersed transformers are most commonly used in African countries is that they can meet electricity demand, are stable and reliable in use, and are adaptable to the environment.

 

 

The three-phase transformers exported to Africa need to meet the following requirements:

 

Compulsory certification: For some countries or regions, it is necessary to obtain mandatory certification certificates, such as GCC, IECEE-CB, CE, UL, etc.

 

License certification: Some countries or regions require license certification, such as Nigeria.

 

Compliance with regulatory requirements: Local regulatory requirements need to be followed, such as compliance with the African Bureau of Standards (BSOA) standards in the African region.

 

Quality assurance: It is necessary to ensure product quality and provide corresponding quality documents and certificates.

 

 

 

Therefore, before exporting three-phase transformers to Africa, it is necessary to understand the regulations and certification requirements of the target market, ensure that the product meets the requirements, and conduct relevant certification and license applications. At the same time, necessary quality assurance documents and certificates need to be provided.
