750 KVA Transformer Price in India – Cost, Features, and Buying Guide

Summary 

When planning for industrial or commercial power needs, a 750 KVA transformer becomes a crucial element in ensuring efficient and stable electricity distribution. These transformers are widely used in factories, hospitals, data centers, large buildings, and infrastructure projects where a steady power supply is essential for smooth operations. Understanding the cost, features, and key considerations before purchasing helps industries make informed and cost-effective decisions.

Price Range and Market Overview

The price of a 750 KVA transformer in India varies depending on design specifications, materials used, manufacturing standards, and additional features. On average, the cost ranges between ₹5 lakh and ₹15 lakh. Manufacturers such as Power Tech Transformers, Servo Star, Perfect Electricals, and Vajra Transpower offer 750 KVA oil-cooled or dry-type transformers within this range. The variation in price is mainly due to differences in cooling systems, copper or aluminum windings, voltage ratings, and protection mechanisms. For instance, a basic oil-cooled transformer may start from around ₹5 lakh, while a high-efficiency model with premium insulation, tap changers, and low-loss materials can reach ₹14 to ₹15 lakh.

The price also depends on whether the transformer is designed for distribution or power applications. Distribution transformers, which step down voltage for localized use, are generally more affordable compared to power transformers that handle higher voltage transmission. Additionally, customization for site conditions, climate, or load profile can influence the total cost.

Features and Technical Highlights

A 750 KVA transformer in India is typically built with high-quality materials to ensure maximum energy efficiency and reliability. The core is usually made from cold-rolled grain-oriented (CRGO) silicon steel, which minimizes energy losses. Copper windings are preferred for their excellent conductivity and longevity, although aluminum winding versions are available at a lower cost. Most units come with ONAN or ONAF cooling systems that prevent overheating during continuous operation.

Transformers of this capacity include features such as tap changers to regulate voltage, protection relays to prevent short circuits, and oil conservators for thermal management. The design focuses on reducing iron and copper losses, maintaining low noise levels, and ensuring consistent performance even under heavy load conditions.

Buying Considerations and Guide

Before purchasing a 750 KVA transformer, it is important to clearly define the voltage levels, load requirements, and installation environment. Industrial buyers should choose models that comply with IS and IEC standards to ensure safety and performance reliability. It is also wise to consider the type of cooling system and loss levels, as these factors influence long-term efficiency. While copper windings offer better efficiency and durability, they are slightly more expensive than aluminum alternatives.

After-sales support is another key factor when selecting a manufacturer. Reputed brands like Shakti Servo and other trusted names provide installation, testing, and maintenance services along with performance warranties. Buyers should also check whether transportation, commissioning, and accessories such as bushings and lightning arresters are included in the quoted price.

FAQs
