Tanks of submersible transformers are made of what two types of metal?

Submersible transformers are typically designed to endure harsh environmental conditions while ensuring safety and efficiency in electrical operations. The tanks that house these transformers are made from two types of metal: stainless steel and mild steel.

Stainless steel is used because of its resistance to corrosion and ability to withstand various environmental impacts, which is essential for maintaining the integrity of the transformer in submersible applications. Mild steel, on the other hand, provides a strong structural framework that can be easily fabricated and welded, making it ideal for creating robust tanks that can contain the transformer components effectively.

The combination of these two metals ensures that the transformer can operate safely under water or in wet environments without deteriorating or compromising the electrical system's functionality. This makes stainless and mild steel the optimal materials for submersible transformer tanks in the electrical engineering field.
