What Makes Tuboly Astronic Such a Widely Respected Winding Machine Manufacturer? 

At Tuboly Astronic, we attend trade fairs and exhibitions to demonstrate our systems and explain what makes us stand out as a winding machine manufacturer. One of the things we are always keen to point out is how reliable our systems are. We have a proven track record in supplying winding machine technology to our clients and continuing to support them thereafter. Our LV and HV foil winding machines showcase how cleverly designed our products are for modern production methods.

The low-voltage winding machinery we make can be used to process large cross-sections of material, even when high winding force loads are called for. Cold pressure welding or TIG welding are deployed to ensure a reliable result without expending additional energy. Our FHV series of winding machines operate with high voltages, but they are just as reliable as our LV systems. These are ideal machines for cast resin transformers, and they even work with an automated foil edge control system.

This helps to ensure quality control with the right tension being applied at all times. In addition to our standard systems, many of the devices we make as a winding machine manufacturer can be automated. For example, insulation for coils of up to 3000 kVA can be made using our automatically operated WHD machines.  Furthermore, automatic strip technology is a common function that you can expect to find in many of our systems, such as those in the WHC and WHL ranges, as well as the WHD.

By deploying this technology, our winding machines can offer either single-strip or double-strip insulation which, crucially, is processed simultaneously with the conductor. It is not just our know-how with automated winding systems that our customers like. We also produce some world-class vertical winding machines to go alongside our horizontal ones. Features like swivelling counter bearings are available to help the mandrel function properly with our vertical systems. Any firm that wants to produce cost-effective results for transposed disc windings, for example, should look into our vertically operated winding machines and the additional possibilities that such technology affords.

At Tuboly Astronic, we don’t think that you will be able to find a superior vertical winding machine anywhere else! Given that what you have read so far is merely an overview of the sort of innovative and carefully designed winding technology we produce, we think that you will be suitably impressed by taking a more in-depth look at some of our main product ranges. Our current clients often report how satisfied they are with them. Remember that if you cannot find a standard coil winding machine for your exact needs, then it is highly likely that we will have produced something for another client that will fit your specifications. We have extensive knowledge of the industry, which is why we are so highly respected in a number of industrial sectors.

Specialist Winding Technology from a Trusted Manufacturer

Tuboly Astronic AG was established in Switzerland in 1988. Since then, we have developed unparalleled expertise in winding technologies, such as coil winding, foil winding, bushing winding and transformer winding. This means we are trusted as a world leader in winding technologies. We can produce effective systems for even the most specialised requirements. Our experience spans diverse industries.

At Tuboly Astronic, our know-how is not only found in the field of transformer coil winding machines but is also relevant to several other market niches. For instance, we make high-quality bushing winding machines that are used in a number of different industrial sectors. You will find these in our BK, BW and BC ranges. What the BK, the BW and the BC machines have in common is that they are each designed to wind insulation bodies for condenser bushings. As specialist systems, they can cope with materials as diverse as craft paper, crepe paper and aluminium foil.

In the case of aluminium, our machines can be used with automatic aluminium cutting and inserting systems, too. These systems maintain a constant diameter of the body, which helps the end product to avoid an electric flashover. Furthermore, either end of the insulation body can be formed into cones or stair-shapes, as preferred. In addition, our effective paper drying systems lessen moisture content to the bare minimum.

Our MRI winding machines are no less trusted by our customers, thanks to a similarly precise engineering approach with plenty of customisable options. Designed to meet the most exacting customer requirements, these machines make use of a highly sensitive and accurate dancer technology that maintains a constantly adjusted wire tension. These specialist winding machines can be supplied with differtent options on request.  Little wonder, then, that our engineering prowess is so widely regarded to be at the cutting edge.

Automation for Consistency and Reliability

Great reliability and consistency of production are achieved through the effective use of automation. Tuboly Astronic machines use automation to optimise certain processes, ensuring consistent quality and reducing costs and production times. For example, our wire winding machines automatically calculate stop points for cooling ducts or taps.

With our vertical coil winding machines, bending is executed automatically. The bending systems are highly configurable in our winding machines. They are also able to cope with a range of operating situations. Single flat wire or CTC conductors are bendable with adjustable height and length parameters. It is also possible to utilise a multiple bending unit, which allows the concurrent individual bending of up to eight single conductors.

Industry Trust and Reliability

Reliability and professionalism are vital for gaining customers’ trust in a winding machine manufacturer. We are very respectful of the relevant laws and regulations in our industrial sectors and our products are certified to meet the following standards:

ISO 9001:2015 Quality Management System

ISO 14001:2015 Environmental Management System

OHSAS 18001:2007 Occupational Health and Safety Management System

We place great confidence in our products and are always keen to demonstrate, discuss and learn. That’s why we regularly attend trade fairs and exhibitions, such as the recent Middle East Energy Conference, held in the Dubai World Trade Centre, UAE, in March 2020. We are also planning to present our devices at the upcoming CWIEME in Berlin in May 2021.

PC Control with Winding Systems

The Advantages of Transformer Winding Machines

In the modern age, what sets one winding machine manufacturer apart from another is the willingness to adopt new digital technology in the pursuit of winding excellence. The team at Tuboly Astronic appreciate this, which is why so many PC-based control systems are now offered with our products. The software and data logging afforded by these computerised systems means that our clients can program each layer of their coils independently if they want to.

This function can vary from firm to firm or even for individual projects if so desired. Basically, our software systems aim to simplify the automation of many coil winding processes. This allows for fewer errors to be made, less wastage to occur and – above – all for our clients to be able to meet their customers’ changing needs with the same level of reliability we like to afford. After all, if your clients like what you’ve produced using our machines, then that is good for us, too.


A good winding machine manufacturer should offer not just a range of products. It should offer also significant configuration options for individual machines. Meeting customers’ closely specified requirements precisely is something we take very seriously at Tuboly Astronic. 

For example, our wire winding machines can, if needed, include winding mandrels, clamping adapters, a round wire flattening unit and overhead decoiler, a rectangular wire decoiler and other options. Our FCCC range of foil winding machines are similarly configurable and may include an optional expandable decoiler shaft, foil cleaning and edge treatment devices, compensation feed roller and many more possibilities.

Specialist Machines

In some cases, Tuboly Astronic provides winding machines with very particular requirements. For example, we offer coil winding machines for MRI units where the most precise winding is essential. As well as the highest accuracy of winding, these machines operate with constant wire tension and crane-free loading. Quality assessment is facilitated by a full data capture of the process. Similarly, our bushing winding machines, used in the production of RIP or OIP condenser bushings. They are sensitive enough to work with both crepe paper and aluminium foil. These machines feature automated cutting systems and an innovative heating system to avoid moisture.

The Advantages of PC Control in Modern Transformer Winding Technology

Much of the manufacturing sector currently benefits from data collection and computerised control systems. At Tuboly Astronic, we are aware that PC control systems are what transformer winding machine manufacturers are increasingly demanding in order to keep with this trend. Of course, the biggest advantages of using computers in manufacturing is to maintain a high standard of quality control.

When transformers – or any manufactured product, for that matter – fail, it is commonly down to a fault that occurred in the manufacturing process and not all manual quality control measures will be able to pick them up. However, when PC control systems are in place, fewer errors are made when a product is put together. With greater precision and less reliance on human intervention, productivity and quality should rise in tandem. 

In short, this means fewer interruptions to your transformer production line to fix issues, earlier identification of problems when they do occur and fewer returned products. This means keeping your clients happier with the products they receive from you along with all the attendant benefits that will facilitate business growth. Ask yourself this: If you can take advantage of the sort of software and automated PC control systems offered by Tuboly Astronic nowadays, why wouldn’t you?
