Transformers are the backbone of modern electricity distribution systems. Whether for industrial use, commercial setups, or residential purposes, a reliable transformer ensures that electricity is efficiently transmitted without loss or damage. Among various transformer capacities, the 63 kVA transformer is one of the most popular choices for small to medium-scale industries, commercial establishments, and agricultural applications. If you are planning to purchase one, understanding the 63 kva transformer price and its key features becomes essential.
In this article, we will break down everything you need to know about a 63 kVA transformer, including its specifications, types, factors affecting price, and maintenance tips. This guide will help you make an informed decision while selecting a transformer for your specific needs.
What is a 63 kVA Transformer?
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. It is used to either increase (step-up) or decrease (step-down) voltage levels as per the requirement.
A 63 kVA transformer refers to a transformer with a capacity of 63 kilovolt-amperes (kVA). Here, kVA is the unit of apparent power, which measures the total electrical power supplied by the transformer. A 63 kVA transformer can handle moderate electrical loads, making it ideal for medium-sized businesses, workshops, hospitals, schools, and agricultural installations.
Key Features of a 63 kVA Transformer
Understanding the main features of a 63 kVA transformer will help you know why it is suitable for your application. Here are the key aspects:
1. Voltage Rating
The voltage rating of a transformer indicates the input and output voltage levels it can handle. Most 63 kVA transformers come in standard voltage combinations such as:
- 11 kV/0.4 kV (for stepping down high-voltage distribution lines to low-voltage residential or commercial use)
- 6.6 kV/0.4 kV
It is important to choose a transformer with a voltage rating that matches your electrical system to ensure safety and efficiency.
2. Load Capacity
The load capacity defines the maximum electrical load the transformer can handle without overheating. A 63 kVA transformer can generally supply:
- Around 50–60 kW of electrical power, depending on the load factor
- Suitable for multiple small to medium-scale industrial equipment running simultaneously
Overloading the transformer can lead to reduced efficiency, overheating, and a shorter lifespan. Always choose a transformer slightly above your estimated load requirement for safe operation.
3. Cooling Type
Transformers generate heat during operation. The cooling type determines how effectively the heat is dissipated. There are two main cooling methods for a 63 kVA transformer:
- Oil-Immersed Transformers: These transformers are submerged in insulating oil, which helps in cooling and prevents electrical breakdown. They are more durable and can handle higher overloads but require proper maintenance to prevent oil leakage.
- Dry-Type Transformers: These transformers use air for cooling. They are safer for indoor installations since there is no risk of oil spillage, but they are slightly more expensive and less tolerant to overload.
4. Efficiency
Efficiency is a measure of how well the transformer converts input power to output power without losses. Most modern 63 kVA transformers have efficiencies ranging from 95% to 98%, which ensures minimal wastage of electricity. High-efficiency transformers may cost slightly more but result in lower energy losses and reduced electricity bills over time.
5. Impedance
Transformer impedance is a measure of resistance against the flow of alternating current. It helps in limiting short-circuit currents and reducing voltage drops. For a 63 kVA transformer, the typical impedance value is around 4–6%, depending on the manufacturer. Correct impedance ensures the safety of your electrical system and protects connected equipment.
6. Construction Quality
The construction quality affects the durability and performance of the transformer. Look for the following construction features:
- High-grade silicon steel laminations to reduce core losses
- Copper or aluminum winding with proper insulation
- Strong casing and weatherproof coating (for outdoor use)
Good construction ensures long life, reliability, and minimal maintenance requirements.
7. Safety Features
Modern transformers come with multiple safety features, including:
- Buchholz relay for detecting gas accumulation in oil-immersed transformers
- Overload protection to prevent overheating
- Temperature sensors for continuous monitoring
- Pressure relief devices in case of sudden internal pressure rise
These features are crucial to prevent accidents and ensure uninterrupted power supply.
Factors Affecting 63 kVA Transformer Price
The 63 kVA transformer price varies depending on several factors. Knowing these can help you plan your budget effectively.
1. Material Quality
- Copper vs. Aluminum Windings: Copper-wound transformers are more efficient and durable but costlier. Aluminum-wound transformers are cheaper but slightly less efficient.
- Core Material: High-grade silicon steel reduces losses and improves efficiency but increases price.
2. Type of Transformer
- Oil-Immersed Transformers are generally less expensive than dry-type transformers of the same rating but require regular maintenance.
- Dry-Type Transformers have a higher upfront cost but lower maintenance expenses and are safer for indoor applications.
3. Brand and Manufacturer
Trusted brands or reputed manufacturers usually charge more due to better quality assurance, warranty, and after-sales support. Budget transformers may have a lower initial cost but can lead to frequent maintenance issues.
4. Voltage Rating and Special Features
Transformers with non-standard voltage ratings or additional safety features like temperature sensors, advanced cooling systems, or digital monitoring will have a higher price.
5. Market and Location
Transformer prices fluctuate based on the cost of raw materials (like copper and steel), shipping charges, and local taxes. Prices may vary slightly depending on your location and the distributor.
Benefits of a 63 kVA Transformer
Investing in a 63 kVA transformer provides multiple benefits:
1. Reliable Power Supply

2. Energy Efficiency
Modern transformers are designed to minimize energy losses, reducing electricity bills in the long term.
3. Flexibility
A 63 kVA transformer can serve various applications, including industries, schools, hospitals, and agricultural operations.
4. Low Maintenance
With proper installation and regular servicing, these transformers can last for 15–20 years, requiring minimal maintenance.
5. Safety
Advanced transformers come with multiple safety features to protect equipment and personnel from electrical hazards.
Maintenance Tips for a 63 kVA Transformer
Proper maintenance ensures a longer life and better performance. Here are some simple tips:
- Regular Inspection: Check for signs of overheating, unusual noise, oil leakage, or rust.
- Clean Environment: Keep the transformer area free from dust, moisture, and debris.
- Oil Testing (for oil-immersed): Regularly test the insulating oil for moisture and contaminants.
- Temperature Monitoring: Ensure the transformer does not exceed its rated temperature.
- Load Management: Avoid overloading the transformer. Always operate within the rated capacity.
Following these simple practices can significantly reduce maintenance costs and prevent unexpected failures.
