750 kVA Transformer Price in India: Complete Guide and Buying Tips

Summary

A 750 kVA transformer is a critical power distribution solution widely used in industrial, commercial, and utility sectors to maintain stable and reliable electricity supply. This medium-to-high capacity transformer is suitable for large industrial units, hospitals, educational campuses, commercial complexes, and high-load manufacturing facilities where uninterrupted power is essential. Its popularity in India has grown with increasing industrialization and infrastructure development, as it provides efficiency, durability, and reliable voltage regulation.

Price of 750 kVA Transformer in India

The price of a 750 kVA transformer in India typically ranges from ₹12 lakh to ₹25 lakh, depending on several factors such as cooling type, winding material, voltage rating, efficiency class, and brand reputation. Oil-cooled copper winding transformers are usually on the higher end due to their enhanced performance and longevity, while aluminium winding models are more cost-effective but may have slightly higher energy losses over time. Additional features like advanced insulation, energy-efficient design, and BIS-certified components also influence the cost.

Specifications

A standard 750 kva transformer price in india operates at a frequency of 50 Hz and is available in primary voltage levels of 11 kV, 22 kV, or 33 kV with secondary voltage output typically at 433 V for industrial or commercial distribution. Most 750 kVA transformers use ONAN or ONAF cooling methods to maintain optimal operating temperatures and extend service life. The Dyn11 vector group is common, ensuring minimal harmonics and stable three-phase power delivery. Compliance with IS 1180 standards and BIS certification guarantees safety, efficiency, and regulatory compliance. Transformers are designed with robust insulation, low losses, and durable enclosures suitable for both indoor and outdoor installations.

Applications

The 750 kVA transformer is widely used in large industrial manufacturing units, textile and chemical plants, food processing industries, and medium-to-large commercial buildings like malls, hospitals, and office complexes. It is also ideal for educational campuses, residential societies with high load requirements, renewable energy integration, and backup power systems supported by DG sets or UPS. By stabilizing voltage and providing reliable power, it helps prevent equipment damage, production downtime, and energy wastage.

Buying Tips

When purchasing a http://shaktiservo.website3.me/blog-2, it is crucial to assess your current and future load requirements to ensure optimal sizing. The choice between copper and aluminium windings affects efficiency, energy losses, and maintenance cost, with copper preferred for continuous heavy loads. Cooling type should match installation conditions; oil-cooled transformers are generally better for high-load and outdoor environments. Ensure the transformer meets BIS certification and IS 1180 standards for safety and reliability. Warranty, after-sales support, and availability of spare parts are equally important for long-term operational efficiency. Working with a trusted manufacturer can also ensure installation guidance and proper maintenance advice.
