With our headquarters in the heart of Europe, located about midway between Zurich and Basel, Tuboly Astronic AG is perfectly placed to serve the needs of any business that requires world-class transformer machinery. We have over three decades of experience in this technology that your enterprise can benefit from. What makes our systems so outstanding? The truth is that there is no single element that makes our transformer machinery any better than others you could find.

One trait that separates our business from the masses involves an innate sense of flexibility. Our industry knowledge has led us to believe that operational requirements should not be associated with a “one-size-fits-all” mindset. Rather, the needs of the individual customer must be taken into account. The trick here is to embrace this notion of malleability without sacrificing quality.

Another core tenet of Tuboly-Astronic involves the ability to establish working relationships with each and every customer. This allows us to fully understand their desires and ultimately provide targeted solutions. Considering the speed at which the entire transformer machinery sector is evolving, this is simply the most logical approach. Why leave anything to chance?

Furthermore, it is the attention to detail that has gone into the design and construction of our systems that adds up to make something superior. This means you can expect reliability but there is so much more to add. In other words, our transformer machines are designed by experts who leave no stone unturned in the pursuit of perfection. If you are now wondering exactly what makes our systems so advantageous, then you should read on to find out what makes the business case for investing in them so compelling.

1. Transformed Efficiency

One of the most important things to take on board about Tuboly Astronic is our business ethos. This goes into everything we do, including the design and production of high-quality transformer machinery. It can be summed up in our slogan: Transform our efficiency into yours. In other words, our vision is to make products that don’t simply do a job for our customers but which add value to their enterprises.

This means our systems must be versatile to meet changing business needs but also efficient so that their productivity can immediately be transformed into something that adds genuine value to our clients. The fact that we are so committed to efficient working practices, which then benefit our clients when they start using our equipment, is evidenced by our quality management systems. As you’d expect, these conform to the exacting standards of ISO 9001:2015.

2. Swiss Engineering Excellence Brought to Modern Transformer Machinery

Modern Transformer Machinery

At Tuboly Astronic, we know that Swiss engineering is something that has a reputation right around the globe. We are proud to continue in this tradition of excellence and know that what we do plays its part in maintaining it. Anyone who has seen our transformer machinery in use will soon realise just how precisely it can be configured. Of course, this is in part due to the aforementioned traditions of engineering excellence that we pursue to this day. It is also down to the fact that our engineers and designers are drawn from some of the most highly skilled individuals available in the labour market. By investing in people, we allow our transformer machinery to better benefit you.

With that being said, it is just as important to mention that flexibility is key in these modern times. We fully understand the fact that transformer manufacturing needs differ from organisation to organisation. This is why we offer a wide range of options in accordance with your discrete requirements.

From specialised core manufacturing configurations to units intended to create MRI machines, little is left to the imagination. As always, we are also happy to provide additional advice when required. Simply contact one of our trained specialists to learn more about your options. Our aim is to effectively address every solution.

3. Computer-Controlled Automation

Explore the Modern Automatic Winding Machines from Tuboly Astronic

We use software and computer-controlled elements in our transformer winding systems more than ever before. After all, this is the way of the world and failing to do so would mean that our products would ultimately fall behind. Today, automation can be found in many aspects of our machinery. Things like remote diagnostic software can be used to help our support engineers to assist you without the time-consuming need to make trips to your premises.

However, it is important to remember that automation will serve few purposes if user-friendly platforms are not adopted. Therefore, our transformer machinery is built in accordance with the needs of the customer. Thus, streamlining real-time operations from scalable configurations to intuitive user interfaces should not present an issue.

This level of on-site intuition is then augmented with a superior sense of modularity. In other words, machines can be combined in order to accommodate your production needs. This would simply not be possible when implementing generic solutions. Why settle for anything less than the most modern manufacturing solutions for your business?

Furthermore, we have also developed a Windows-based control system for your own operatives to use. This makes set up times for new production runs as short as possible. It also means that an internationally standardised approach can be taken to automation, which is of benefit to all concerned. You can use such software to quickly set up automated stopping points and to create workflows that can be conveniently shared between systems.

4. Differing Strip Insulation Levels to Suit All Needs

Our strip insulation levels provide complete flexibility. In other words, they allow for the conical arrangement of the insulating material to automatically fill the end of the cone. For our HV wire winding systems, which are ideal for forming transformers, there are three strip insulation levels you can opt for. 

The importance of strip insulation within transformer coils cannot be overstated. Without this type of insulation, electricity would automatically follow the path of least resistance. It would simply jump from wire to wire rather than through the wires themselves. As a result, creating a magnetic field would be impossible. This negates the entire purpose of a transformer.

As should be expected, there are numerous variables that need to be accounted for when installing strip insulation. Once again, this is when the concept of automation comes into play. Tuboly-Astronic has created several proprietary methods that our customers can choose from.

Thanks to the dancer-controlled tensioning systems that come with the HV range, radial tolerances are reduced while full-width insulation remains possible. You can see this in our WHL series, for example. The HV range also includes the WHC series, which allows for coils of up to 600 kVA, while the WHD series can produce 3,000 kVA. 

5. Wire Tensioning Processes

When you invest in our transformer machinery, you can keep the tension of the wire your system is winding at the same level with ease. This is thanks to our motor-driven and dancer-controlled brake rollers, which work in the background to keep the tension at the same level no matter where you happen to be in the process.

Why is constant tension so important when manufacturing transformers? As this article notes, uneven tension can lead to several problems. It can cause malformed coils, problematic installations, and even electrical short circuits. The issue here is that manual winding can represent a laborious and time-consuming process. Furthermore, accuracy is often called into question.

Therefore, automatic tensioning systems are preferred, as these combine efficiency with reliability. These configurations are even more relevant within environments associated with high throughput. Once again, the user-friendly nature of our systems helps to provide superior levels of operational oversight.

What’s more, this precise wire tensioning can be achieved with either round or rectangular wire, something that is not always possible with inferior equipment. Furthermore, with our proven flattening units, any round enamel-insulated wiring can be rolled into a flattened state with remarkable ease at an adjustable height that suits your particular needs. 

6. Exceptional Support and Servicing 


All of the transformer machinery made by us is designed for durability. It should run without any issues for many years. That said, any technology is only as good as the support it receives and this is certainly the case with our products. At Tuboly Astronic, we take great pride in the technical support we offer our many clients. This can often be achieved by using diagnostic software to detect problems even before they might occur.

It can also be delivered by reaching out to our support team in person, either by email or over the phone. We have dedicated engineers who have the right experience to deal with service issues. This includes technical support assistance, spare parts support and even retro-fitting help.

Simply stated, we believe that ongoing assistance is the key to long-term success. This is perhaps one of the reasons why Tuboly-Astronic has enjoyed industry-wide recognition for more than 30 years. Let’s also remember that robust levels of customer support make good business sense.

Perhaps you have a question about a specific winding model. You might instead be interested to learn about the applications of a coil winding machine. Either way, our dedicated service centre is always here to help address your queries. Do not hesitate to take a closer look at your various service and support options.

We believe that no other transformer machinery made today receives such exceptional levels of ongoing business support once it has been installed.


Perhaps the main takeaway point in regard to the information above is that the industry is constantly evolving. Solutions that might have been appropriate yesterday could be outdated in the near future. Therefore, cookie-cutter approaches will no longer suffice. Customers require targeted transformer machinery to accommodate demanding operational needs.

Tuboly-Astronic has remained at the forefront of this sector for over three decades, and this reputation continues to grow. This is why we encourage you to take a closer look at what we have to offer you. There is no doubt that you will be quite impressed with what is in store.
