400 KVA Electrical Transformer: Efficient Power for Industrial

Summary

A  400 KVA electrical transformer is a reliable and efficient power solution designed to handle the demanding needs of industrial and commercial facilities. It plays a crucial role in ensuring a stable and safe power supply by stepping down high-voltage electricity from the grid into a usable voltage for various applications. Industries that rely on continuous operations and precision equipment greatly benefit from transformers of this capacity due to their durability and consistent performance.

Overview of 400 kVA Transformers

A 400 kVA transformer is typically used in medium to large industrial units, manufacturing facilities, hospitals, and infrastructure projects where stable power distribution is essential. The transformer ensures smooth voltage regulation, preventing machinery damage caused by fluctuations or surges. These transformers are available in oil-immersed and dry-type configurations. The oil-immersed model is preferred for outdoor installations because it provides superior cooling and long-term reliability, while the dry-type model is ideal for indoor use, offering fire resistance and low maintenance.

Price Range and Specifications

The price of a 400 kVA electrical transformer in India generally ranges from ₹4 lakh to ₹8 lakh, depending on the type, material, efficiency class, and manufacturer. Copper-wound transformers are more efficient and durable compared to aluminum-wound models, though they come at a slightly higher cost. Cooling methods like ONAN (Oil Natural Air Natural) or ONAF (Oil Natural Air Forced) influence both efficiency and longevity. Leading brands such as Shakti Servo manufacture high-performance 400 kVA transformers that meet BIS and IEC standards, ensuring reliability, safety, and energy efficiency.

Key Features and Benefits

A 400 Kva Transformer is built to deliver superior energy efficiency by minimizing load and no-load losses. It is constructed using high-quality core materials and advanced insulation systems that enhance durability. The transformer’s design supports continuous operation under varying loads while maintaining low noise levels. It also offers high thermal stability and strong overload capacity, making it suitable for industries that operate round the clock. With proper installation and maintenance, these transformers can last over two decades, offering long-term value and consistent output.

Applications

A 400 Kva Transformer finds applications in factories, hospitals, commercial complexes, educational institutions, and renewable energy projects. It ensures an uninterrupted power supply, protecting sensitive electrical equipment and improving operational efficiency. In manufacturing setups, it supports heavy machinery and production lines, ensuring smooth performance even under fluctuating grid conditions.
