Transformers
Utilligence makes, designs, builds, supplies and installs a wide range of transformers. Whether it’s step up, step down or low or high voltage, we have a comprehensive range of transformers to meet the needs of our customers.
- Power transformers
- Distribution transformers
- Cast resin transformers
- Low loss transformers
Power transformers are essential components that enable DNOs to efficiently distribute electricity at different voltage levels, ensuring a reliable supply.
While off-the-shelf solutions might be adequate for some scenarios, they often fall short of meeting the specific requirements of DNOs, who have unique and demanding operational needs, including high power capacities, complex grid configurations, stringent safety standards and diverse load demands and environmental factors. Bespoke power transformers which are tailored to the precise needs of each DNO are imperative for ensuring optimal performance and operational efficiency.
Utilligence are expert in the design and manufacturing of power transformers for DNOs. We understand load fluctuations, cooling systems, insulation materials, and protection mechanisms. Investing in bespoke power transformers enables DNOs to mitigate potential risks, enhance reliability, and maximise the lifespan of the transformers, optimising the overall performance of their power grid.
Whether you need a maintenance solution, a simple replacement for a single distribution transformer or a complete overhaul of your power solution, we can help. Our customers benefit from world-class solutions, competitive pricing and the attention to detail of our consultancy-style approach.
Our design team has expert low and high-voltage engineers to ensure that we can design transformers and control systems of any size, voltage or type.
For customers who are making the move towards net zero, we also offer transformers that harness biodegradable, non-corrosive oils, as well as solid-state versions. As part of our bespoke service, we can design to your unique safety requirements, or a transformer that operates under specific fault conditions. You tell us what you need, and we’ll design it!
Utilligence also offers a transformer testing and diagnostic service, to identify transformer issues and optimise performance.

Low loss distribution transformers
We provide transformers that meet tiers one and two of the EU Eco Design Directive and are fully compliant with industry standards, including BS, IEC and ANSI.
For a transformer with reduced fire risk and optimised environmental performance, our efficient distribution transformers are an ideal option, to support adherence to the stringent environmental standards of your site. We have distributed transformers available that use fully biodegradable transformer fluid, with the added benefit of enabling a safe increase on transformer loading, or a transformer size reduction.
Our focus is on maintaining maximum efficiency, minimising power loss and saving you money over the lifetime of your transformers. This commitment to environmental performance can also be used to support your adherence to environmental standards such as ISO 14001.
A wide range of switchgear can complement all of our power transformers – either closed coupled or free standing as required.
All of Utilligence’s transformer designs can be configured to meet your specific requirements - get in touch to find out how we can help.
Distribution transformers
Utilligence provides both standard and custom-designed distribution transformers. Our manufacturing team can craft these transformers in radiator style, corrugated tank, or cast resin, ensuring a range of options to suit your needs.
A distribution transformer plays a crucial role in stepping down voltage levels for efficient electricity distribution. Drawing on our extensive experience, we have successfully delivered tailored solutions for a wide variety of applications. Whether it's for industrial, commercial, residential, or renewable energy use, our distribution transformers can be adapted precisely to meet your specific requirements.
We offer a range of insulation options, including liquid-filled and dry, with reduced fire risk and improved environmental features.
Power transformers
Whatever your power needs, we can provide the solution, with the capacity to supply transformers, from 5MVA to 1000MVA and 415V to 750kV.
Our power transformers are made for your specific needs. Committed to quality, we source our components from the world’s best suppliers and manufacture to our own high standards.
We work closely with you throughout the entire process, from manufacturing to delivery and installation.
Our highly experienced engineers will support you from your initial enquiry until the successful completion of your project. You can rely on outstanding technical support coordinated by a dedicated account manager.
Package transformers
We offer MV or LV mounted, free-standing, distribution boards and complete containerised solutions.
Cast resin transformers
We manufacture and supply up to 25MVA and 36kV. Our cast resin transformers can be provided in an IP55 enclosure and fans to improve performance and energy rating.
Other transformers
We also offer eco-friendly, increased impedance, non-standard voltage, special tank and bespoke connection transformers, and a range of combi, and cast resin transformers – contact us for more information.
Switchgear
We work closely with world-leading manufacturers such as ABB and Schneider, to provide a range that spans from simple ring main units to full distribution boards with a voltage up to 36kV.
Transformer servicing and O&M
We offer a wide range of O&M services, to ensure that your transformers are well-maintained and any issues are responded to promptly by our highly trained support team. Our customers benefit from our professional expertise which ensures the optimal performance and longevity of your electrical infrastructure.
