Types of Transformers for Data Centres

SES Isolation Transformers: Reliable Power Solutions

If you need stable, clean power to protect sensitive equipment from electrical noise, surges, and interference, isolation transformers are your best choice. 

At Southern Electronic Services (SES), we specialise in high-quality isolation transformers that deliver exceptional performance and reliability across a wide range of industries, from industrial operations to commercial projects, including data centre transformers for critical IT infrastructure.

What Are Isolation Transformers and Why Are They Important?

Isolation transformers separate primary and secondary windings, preventing the direct flow of current between them. This design enhances safety, improves power quality, and provides protection against electrical surges and interference, which can otherwise damage equipment and disrupt operations. 

Isolation transformers are especially valuable in environments that rely on stable power, such as manufacturing facilities, medical equipment setups, and commercial buildings.

SES Isolation Transformers: Quality, Flexibility, and Durability in One Place

SES Isolation Transformers are engineered to meet all of your requirements, combining quality materials and customisation options to ensure they fit any application. Here’s what makes SES Isolation Transformers stand out:

1. Versatile 3-Phase Isolation Transformers

SES offers a versatile range of 3-phase isolation transformers, ready for hardwiring into various systems. With the option to customise input/output and configuration settings, these transformers can be adapted to meet the demands of industrial, commercial, or specialised applications.

2. LV Dry-Type Transformers up to 750kVA

SES’s LV dry-type isolation transformers offer power ratings of up to 750kVA. Dry-type transformers are ideal for indoor use and areas where fire safety is a concern, as they don’t require oil for cooling. This makes them perfect for a wide range of applications, from factories to commercial buildings.

3. Custom Input/Output Designs up to 3.3kV

While our standard isolation transformers are rated for 415V/415V input and output, SES can custom design transformers to support voltages up to 3.3kV. 

This flexibility allows our transformers to integrate seamlessly into almost any power setup, ensuring compatibility with your project’s specific requirements.

Isolation Transformers Made with High-Quality Components

SES isolation transformers are crafted from top-grade materials to ensure durability and efficiency:

• Enamelled Copper Windings: Our transformers are wound with enamelled copper, which enhances conductivity and longevity.
• High-Grade Electrical Steel Cores: We use high-quality steel in our cores, which minimises energy losses and ensures optimal performance.

Standard and Customisable Configurations

Our standard isolation transformer configuration is Delta/Star (Dyn11), which is commonly used for balanced power delivery and reliable grounding. However, SES offers full customisation options to suit your specific needs, including:

• Electro-Static Shielding: This option minimises electromagnetic interference (EMI), improving power quality.
• Off-Load Tapping: Allows for fine voltage adjustments to suit various requirements.
• Additional Switchgear: Provides added control and functionality as needed.

Customisation Options for SES Isolation Transformers

Built for Demanding Conditions: Class H Insulation (180°C)

SES Isolation Transformers come with Class H insulation, rated for operation in temperatures up to 180°C. This high-temperature tolerance means our transformers can perform in demanding settings, such as industrial facilities or environments where equipment may run continuously.

Enclosures Designed for Durability

SES isolation transformers are housed in durable enclosures, available in:

• IP33 (Indoor): Protects against dust and accidental contact.
• IP65 (Outdoor): Provides high resistance to dust and water, ideal for outdoor installations.

These heavy-duty enclosures are made from powder-coated mild steel, ensuring longevity and resistance to environmental wear. Additional custom enclosure options are available upon request, allowing SES transformers to perform reliably in both indoor and outdoor environments.

Designed to Handle Harmonics with tailored K-Factor Design 

Many applications, particularly those with electronic equipment, create harmonic currents that can lead to transformer overheating. 

SES Isolation Transformers come with a standard K4 K-Factor rating, but can be designed to accommodate any K-factor requirement, enabling them to handle these harmonic loads effectively. For projects that include non-linear loads, such as those in manufacturing or medical facilities, the K4 rating ensures transformers remain cool and operate efficiently.

Reliable and Fast Delivery

SES maintains high inventory levels of quality materials, ensuring that we can produce and deliver your transformer on schedule. Our efficient production process guarantees that we meet your timeline without sacrificing the quality and reliability of our products.

Final Thoughts

SES Isolation Transformers offer unmatched reliability and performance, with customisation options to fit nearly any application. 

Built with high-quality components and available in various configurations, SES transformers are the ideal choice for projects requiring stable, clean power, whether in manufacturing, commercial, medical, or specialised industrial settings.
