Leeds Transformer
Air Cooled Transformers
Leeds Transformer specialises in the design and manufacture of bespoke air-cooled transformers, tailored to meet diverse industrial applications. Our air-cooled range includes single and three-phase double-wound (isolating) transformers with ratings up to 500 kVA and up to 300kVA as Ecodesign (larger for Auto Transformers) and maximum service voltages up to 11 kV. These transformers are particularly suitable for installations where space constraints exist, as they can be integrated into switchgear cabinets or ventilated cubicles.
The absence of liquid coolant in these designs not only reduces environmental concerns but also minimises maintenance requirements. Leeds Transformer air-cooled transformers are ideal for applications requiring reliable performance in confined spaces, offering efficient voltage conversion without the complexities associated with liquid-cooled systems.
We also offer British Gas/Transco/National Grid-approved isolation and supply transformers, as well as Buck/Boost transformers for voltage regulation. Additionally, Leeds Transformer manufacture combined LV transformers and MCB distribution cubicles for safety supplies, and custom-built transformers tailored to specific requirements, including enclosures designed to fit unique spaces or match existing equipment. Our commitment to quality is evident in their adherence to British and international standards, with all products conforming to ISO 9001:2015.

Leeds Transformer Air Cooled, Double Wound (Isolating) Transformers are expertly designed and manufactured to meet a wide range of application requirements. Standard units are available up to 500kVA, while Ecodesign Tier 2 compliant models can be produced up to 300kVA, both supporting voltages up to 6kV. These transformers are ideal for installations where oil or liquid cooling is not suitable, offering reliable performance with minimal maintenance.
Our air cooled isolating transformers provide effective electrical separation between circuits, ensuring enhanced safety and protection for your equipment and personnel. Whether you require a standard configuration or a fully bespoke solution, our engineering team is ready to assist. Please contact us with your specific requirements, and we will work with you to deliver a transformer that fits your exact needs.
Leeds Transformer continues to demonstrate a strong commitment to environmental sustainability through the ongoing development and production of advanced, energy-efficient transformer solutions. With a clear focus on reducing environmental impact and improving power system performance, we have expanded our innovative product lines to include a comprehensive range of ECO and Ecodesign transformers. These include highly efficient voltage-matching buck and boost transformers, which play a crucial role in optimising voltage levels across various applications, ensuring improved system stability and energy use.
In addition, our ECO range features specialised K-Factor transformers, purpose-built to address the unique challenges posed by harmonic currents generated by non-linear electrical loads. These harmonics, if left unmanaged, can lead to excessive heat buildup and equipment stress. Leeds Transformer’s K-Factor designs help minimise these thermal effects, promoting longer equipment life and significantly enhancing overall energy efficiency. As a result, the use of these transformers supports a marked reduction in energy consumption and operational costs, aligning perfectly with sustainable energy goals.
Leeds Transformer also provide harmonic current reduction transformers: state-of-the-art systems engineered specifically to combat the issues caused by harmonic distortions in modern electrical networks. Harmonics can compromise power quality, affect sensitive equipment, and lead to system inefficiencies. Leeds Transformer’s solutions actively mitigate these distortions, ensuring smoother operation and improved electrical performance across a wide range of industrial and commercial settings.
Through the integration of these advanced transformer technologies, Leeds Transformer delivers more than just power conversion solutions – we provide forward-thinking, environmentally responsible innovations. Each product is designed not only to meet and exceed demanding industrial power requirements, but also to contribute meaningfully to broader environmental sustainability initiatives. By prioritising efficiency, reliability, and ecological impact, Leeds Transformer positions ourselves as a leader in the transition toward greener, smarter energy infrastructure.
Leeds Transformer Air Cooled, Auto (Single Winding Non-Isolating) Transformers are designed and manufactured precisely to your project requirements, offering a compact and efficient solution where electrical isolation between primary and secondary circuits is not necessary.
