What is the difference between distribution transformer and Immersed Transformer?

Distribution Transformer vs Immersed Transformer: The Farady Difference

Power distribution plays a vital role in maintaining a steady supply of electricity to our homes, businesses, and industries. At the heart of this distribution system are transformers, responsible for stepping down the high voltage power from the grid to a safe and usable level. When it comes to transformers, two major types dominate the market: distribution transformers and immersed transformers. In this article, we will explore the key differences between these types, with a particular focus on Farady’s product offerings.

What is a Distribution Transformer?

A distribution transformer is a step-down transformer that reduces the high voltage power received from the substation to a lower level suitable for commercial and residential use. It is a crucial element in power distribution systems, distributing electricity from the main transmission lines to the consumer’s premises.

Difference between distribution transformer and Immersed Transformer

The role of a transformer is crucial in the process of transmitting electricity from power plants to our homes and businesses. It converts high voltage electricity into low voltage electricity, making it safe and usable for everyday consumption. There are various types of transformers available in the market, such as distribution transformer and immersed transformer. In this article, we will compare and contrast these two types of transformers, focusing on the products offered by Farady – a leading company in the field of power transmission and distribution.

Part Ⅰ: Material of Distribution Transformer and Immersed Transformer

Farady is a renowned company that specializes in manufacturing and supplying high-quality power distribution solutions. In their extensive product range, two types of transformers stand out – distribution transformer and immersed transformer. While both these products serve the same purpose of converting high voltage power to low voltage power, there are some notable differences between them in terms of their construction and performance.

One of the major differences between these transformers lies in the materials used in their construction. It is usually made from high quality copper or aluminum for windings, which ensure efficient and reliable performance. On the other hand, immersed transformers are typically made from magnetic steel, which allows for a smaller and lighter design. These two different materials have their own benefits and are carefully selected by Farady to suit the specific requirements of their customers.

Part Ⅱ: Transformer Losses

Distribution transformers and immersed transformers also differ in terms of their losses. Transformer losses refer to the energy lost in the process of converting electrical energy from one form to another. These losses can be classified into two types – copper losses and iron losses. Copper losses are caused by the resistance of the copper windings, while iron losses are caused by the magnetic properties of the core material.

Due to the nature of their construction, distribution transformers have lower copper losses as compared to immersed transformers. This is because they use high-quality copper or aluminum windings, which have lower resistance. However, due to the use of magnetic steel in their construction, immersed transformers have lower iron losses. Farady ensures that both their distribution and immersed transformers are designed to minimize losses, making them highly efficient and cost-effective options for their customers.

Part Ⅲ: Turns Ratio

Another important factor that sets distribution transformers apart from immersed transformers is the turns ratio. The turns ratio is the ratio of the number of turns of wire in the primary winding to the number of turns in the secondary winding. It determines how much the voltage is stepped down in the transformer.

Distribution transformer usually have a lower turns ratio as they are designed to convert high voltage to low voltage for distribution purposes. Immersed transformers, on the other hand, have a higher turns ratio as they are used for step-up applications, such as in power generation. Farady offers a wide range of turns ratio options for both distribution and immersed transformers to cater to the diverse needs of their customers.

Part Ⅳ: Cost Performance

Cost performance is a crucial consideration for any product, and it is no different when it comes to distribution transformers and immersed transformers. Distribution transformers are relatively more expensive than immersed transformers due to their use of high-quality copper or aluminum windings. However, this higher cost is offset by their lower maintenance and replacement costs in the long run.

In contrast, immersed transformers are relatively cheaper due to their use of magnetic steel in construction. They are also easier and quicker to install, further reducing the overall cost. Farady manufactures both types of transformers with utmost precision and quality control, ensuring that their customers get the best value for their investment.

Part Ⅴ: Safety Considerations

Safety is a critical factor to consider when selecting a transformer for any application. Both distribution and immersed transformers have different safety considerations due to their unique designs. Distribution transformers have higher insulation and are generally installed in outdoor areas, making them less susceptible to accidents.

Whereas, immersed transformers have a more compact and secure design due to their use of magnetic steel and are usually installed indoors. Farady takes stringent measures to ensure the safety of their transformers, following all necessary standards and regulations, to provide their customers with a reliable and safe product.

Part Ⅵ: Core of Distribution and Immersed Transformer

The core is the most important component of any transformer as it provides the magnetic path for efficient power conversion. The core of distribution transformers is made from laminated silicon steel, which provides high magnetic permeability, thus increasing the efficiency of the transformer.

In comparison, the core of immersed transformers is made from magnetic steel sheets, which are tightly stacked together to form a compact core. This design reduces the energy losses in the core and also allows for a more compact and lightweight transformer. Farady pays special attention to the design and quality of the core in both their distribution and immersed transformers to ensure optimal performance.

Part Ⅶ: Insulation of Distribution and Immersed Transformer

Insulation is crucial in transformers to prevent any electrical breakdown or accidents. Both distribution and immersed transformers have different insulation systems. Distribution transformers have a high insulation level, mostly due to their outdoor installation. They also have additional features such as neutral grounding to ensure safety.

Immersed transformers, on the other hand, have a more compact and efficient insulation system. They are designed to withstand high voltages and have multiple layers of insulation for added protection. Farady constantly invests in research and development to improve their insulation systems, ensuring the safety and reliability of their transformers.

In conclusion, while both distribution transformer and immersed transformer serve similar purposes, they have distinct differences that make them suitable for specific applications. Farady offers a wide range of options for both types of transformers, with their focus on quality, efficiency, cost-effectiveness, and safety. Their commitment to continuous research and development, along with their highly skilled team of engineers, ensures that their transformers are of superior quality and meet the highest standards of performance and reliability.
