Transformer Types and Their Role in Reliable Energy Systems | Nasaen Energy

Electricity is the foundation of modern life — powering industries, cities, and homes across the globe. To ensure energy is transmitted safely and efficiently, the right type of transformer plays a vital role at every stage of the power network.
At Nasaen Energy, we provide reliable transformer solutions from trusted global manufacturers, ensuring every project meets high efficiency and safety standards.

What Is a Transformer?

A transformer is an electromagnetic device designed to transfer electrical energy between circuits through electromagnetic induction. It adjusts voltage levels — either stepping them up for transmission or stepping them down for distribution — while maintaining the same power level.

This process ensures efficient long-distance energy transmission, reduces losses, and stabilizes voltage levels throughout the electrical grid.

Types of Transformers Offered by Nasaen Energy

Our portfolio includes a wide range of transformer types designed for different operational and environmental requirements. Each is sourced from certified, high-quality manufacturers and selected according to project needs.

1️⃣ Dry-Type Transformers

Dry-type transformers are air-cooled or resin-encapsulated, making them ideal for indoor environments where safety and low maintenance are priorities.

• Fire-resistant and environmentally friendly
• No oil required — minimal maintenance
• Commonly used in hospitals, commercial buildings, and renewable energy systems
• Silent operation and compact design

2️⃣ Hermetically Sealed Distribution Transformers

Hermetically sealed transformers are designed for distribution networks that require a fully enclosed, maintenance-free system. The transformer tank is completely sealed to prevent oxidation and moisture entry.

• Maintenance-free, long service life
• Compact and robust design
• Ideal for outdoor and underground networks
• Highly resistant to environmental conditions

3️⃣ Conservator-Type Distribution Transformers

Conservator-type transformers include an oil conservator tank that compensates for oil expansion and contraction during temperature changes. These are widely used in high-demand distribution systems.

• Oil-cooled for superior heat dissipation
• Long lifespan with high efficiency
• Suitable for rural and urban distribution grids
• Ease of monitoring and oil filtration maintenance

4️⃣ Power Transformers

Power transformers are essential for high-voltage transmission networks. They step up voltage levels at power plants and step them down at substations for regional distribution.

• Used in generation plants and transmission substations
• High capacity and superior insulation systems
• Low energy loss and long-term reliability
• Critical for efficient bulk power transmission

5️⃣ Voltage Transformers

Voltage transformers (VTs) are precision devices that measure and monitor voltage in high-voltage systems. They ensure the safety of measurement instruments by providing a scaled-down version of the system voltage.

• Used in protection and metering circuits
• Accurate voltage monitoring and isolation
• Essential for grid control and automation systems

6️⃣ Current Transformers

Current transformers (CTs) convert high current levels into measurable, lower values for monitoring and protection. They are indispensable in energy measurement, protection relays, and control applications.

• Provide accurate current readings for system safety
• Protect sensitive devices from high current levels
• Used in power plants, industrial facilities, and substations

7️⃣ Special Production Transformers

For unique or demanding applications, Nasaen Energy offers customized transformer solutions developed in collaboration with specialized manufacturers.

• Tailor-made designs for specific voltage, capacity, or environmental requirements
• Applications include renewable energy projects, marine systems, and heavy industry
• Produced according to international standards (IEC, ANSI, ISO)
