1. HV wire winding machine

It is suitable for prodcing coils for a distribution transformer. They are ideal for three types of insulation; namely, single strip insulation, double strip insulation and layer insulation.

HV wire winding machines are available in three models with different strip insulation levels. They are:

  • WHC series winding machines: For coils up to 600kVA
  • WHD series winding machines: For coils up to 3000 kVA
  • WHL series winding machines: Full-width insulation.

What user-friendly solutions do these wire winding machines provide? 

Note that these HV wire winding machines are also beneficial due to their level of automation. They can be easily integrated into an existing workflow. Furthermore, customers are provided with remote support solutions in the event of an issue or question. 

Once the correct parameters have been entered, all subsequent calculations will be performed automatically. This is advantageous when dealing with demanding workflows. All Tuboly-Astronic wire winding machines are provided with a full lifetime warranty. 

Having said this, it is important to take a quick look at what sets these units apart from their competitors.

Key features

Strip insulation technology: This allows the conical arrangement of insulation and automatically fills the end of the cone with the same insulation strip(s). The technology comes with dancer-controlled tension that improves the filling factor and reduces radial tolerances.

A dancer-controlled brake system: It maintains the pre-set tension of the conductor by regulating the brakes for various shapes. Consequently, one can achieve a perfect layer even at high winding speeds.

Automatic insulation strip cutting and reattachment system: This system ensures zero stops in the winding process by automatically cutting strips and re-attaching them where necessary. This patented solution is only available on our WHC machine type with one insulation strip.

Flattening unit: It flattens round wires to increase the filling factor. It results in smaller dimensions, less core and conducting materials, and, consequently, the tank volume. The overall benefit of this unit is a significant reduction in the transformer production cost.

Benefits of the features

  • Constant wire tension even when working on different shapes.
  • Constant insulation strip tension.
  • Automatic filler insertion at the ends of the conical layer builds on WHD machines.
  • High filling factor.
  • Significant savings on coil materials.
  • Easy to wind both rectangular and round wires.
  • Optimised material storage and purchasing due to standardized insulation dimension.

The FCCC Series 

The FCCC series employs cold pressure welding as opposed to TIG processes. Similar to the other wire winding machines produced by Tuboly-Astronic, the FCCC is modular in nature. It can also be programmed via in-house methods or with the help of our team. Note that the FCCC 1000 is capable of addressing foil widths between 200 and 1,000 millimeters.

Key Features

Conductor foil decoiler: Each decoiler has an automated brake system to ensure constant foil tension. A diameter compensation system keeps the tension always constant. Insulation decoiler: One can install one or two insulation decoilers to maintain the tension of the insulation.

TIG welding unit: It comes with a high-precision automatic guiding unit, an integrated motor, and clamping jaws. The combination makes it easy to create perfect thick foils and an automated welding process.

Cold pressure welding: The most efficient way to connect the conductor foil with the leadouts (busbars). The following functions are automated in the process: grinding for copper foils, pressure adjustment, pressing process and positioning of downholders.

Motor-driven roller knife: It cuts the foil at pre-set points.

Benefits of the features

  • Controlled foil and insulation tension with automatic diameter compensation.
  • Controlled foil edge control
  • Automated programmable stopping points throughout the entire winding process
  • Operator guidance on colour touch screen
  • Easy to use software with touch screen navigation.

Automatic winder unit: It has a sliding frame system that holds the head and adjustable tailstock. The unit automatically shifts to new disc positions during continuous foil winding. This helps to increase production capacity while not sacrificing quality.

Automated TIG welding unit: It automatically welds the conductor foils to the leadout or disc connections. The welding positions and the speed of the welding torch are pre-calculated.

Benefits of the features:

  • High-quality continuous winding due to the precise sliding system.
  • Constant foil and insulation tension.
  • Automated highly precise TIG welding system.
  • Automatic foil edge control system.
