750 kVA Transformer Price in India – A Complete Buyer’s Guide

Summary

A 750 kva transformer price in india is a vital component in industrial and commercial power systems, ensuring reliable voltage transformation and efficient energy distribution. These transformers are commonly used in factories, hospitals, large offices, and housing complexes to step down high-tension power to usable low-tension voltage. In India, the demand for 750 kVA transformers has increased significantly due to expanding infrastructure and manufacturing growth.

Understanding a 750 kVA Transformer

A transformer rated at 750 kilovolt-amperes (kVA) can efficiently handle large electrical loads. Typically, it steps down voltage from 11 kV or 33 kV to 433 V, providing stable output for machinery, motors, and commercial systems. Depending on the site conditions, 750 kVA transformers come in oil-cooled and dry-type (cast resin) variants. Oil-cooled transformers are ideal for outdoor use, offering high cooling efficiency, while dry-type units are suited for indoor installations where fire safety is crucial.

750 kVA Transformer Price in India

The price of a 750 kVA transformer  in India generally ranges from ₹6 lakh to ₹15 lakh, depending on technical specifications, build quality, and brand.

• Standard aluminum-wound oil-cooled units cost around ₹6 – ₹8 lakh.

• Copper-wound and energy-efficient transformers are priced between ₹10 – ₹15 lakh.

• Premium customized models with On-Load Tap Changers (OLTC), low-loss cores, or smart monitoring features may exceed ₹18 lakh.
  
  

Brands such as Shakti Servo, Kirloskar, Servostar, and Schneider Electric manufacture BIS-certified and high-performance transformers designed to meet industrial power requirements.

Key Factors Affecting Transformer Price

Several factors determine the final price of a 750 kVA transformer:

1. Winding Material: Copper provides better efficiency and durability but costs more than aluminum.

2. Cooling Type: ONAN (Oil Natural Air Natural) or ONAF (Oil Natural Air Forced) systems affect pricing and cooling capacity.

3. Core Material: High-grade CRGO steel or amorphous core materials reduce losses and increase lifespan.

4. Energy Efficiency Class: Transformers with low no-load and full-load losses are slightly costlier but save electricity over time.

5. Accessories & Features: Tap changers, relays, temperature indicators, and protection devices influence cost.

6. Testing & Certification: Transformers tested to IS/IEC standards and supplied with warranties usually have a premium price.
   
   

Benefits of Using a 750 kVA Transformer
