At Transformers & Rectifiers Ltd., quality and precision are at the heart of everything we do. Every transformer we manufacture is the result of decades of engineering experience, skilled craftsmanship, and a dedication to excellence that has defined our company since 1951.
Today, we take a closer look inside one of our essential manufacturing processes — the creation of disc windings, a critical component in many of our transformer designs.
Precision Engineering for Reliable Power
The disc winding shown here has been expertly produced from copper strip conductors with Kraft paper insulation — a well-proven design widely used on 33 kV power systems. This configuration is renowned across the power industry for its mechanical strength, thermal stability, and long-term reliability under demanding operating conditions.
Disc windings play a vital role in ensuring efficient electrical performance and resistance to short-circuit forces, helping to safeguard both the transformer and the wider network. Their layered, compact structure allows for uniform voltage distribution and improved heat dissipation, leading to greater operational safety and efficiency.
Custom-Made Solutions for Every Application
No two projects are the same. At Transformers & Rectifiers Ltd., each transformer is custom engineered to meet the exact needs of the customer and the application. Our in-house design and manufacturing teams work closely with clients across industries — from utilities and transport to industrial power and renewable energy — to deliver solutions that perform reliably in even the most challenging environments.
Our transformers are designed, built, and tested at our factory in Guildford, Surrey, then supplied to customers not only across the United Kingdom but also to destinations around the world. This global reach reflects the continued confidence our partners place in the T&R name and our reputation for engineering integrity.
Craftsmanship You Can Trust
Behind every winding, coil, and core lies the dedication of our highly skilled team — engineers, technicians, and craftspeople whose attention to detail ensures that each unit meets our exacting standards. Their experience and commitment form the foundation of our success and are central to maintaining the trust of our worldwide customer base.
We would like to extend a sincere thank you to our entire team for their continued hard work, and to our customers for the confidence they place in us. It is this partnership — between craftsmanship and trust — that drives everything we do.
