TH Syncro, the new CTC transposing machine by Proteco

TH Syncro, the new CTC transposing machine by Proteco

Proteco srl is an Italian company specializing in the construction of machines for the production of CTC cables. The majority of its activity is directed, since the very beginning, to R&D, to enhance the process technology and create new products.
 
In the CTC field, one of the priorities, when it comes to product evolution, is to produce transposed cables with enamelled strips thinner and thinner; this in order to reduce the Foucault currents, which are detrimental as orthogonal to the main current flow. Of course, a reduced thickness of the strips requires a higher amount of them to get the same total cross section area for the current flow. A higher number of strips leads in turn to a reduction of the transposition pitch, in order to maintain the possibility to easily wind the cable in the transformer.
 
Proteco’s efforts in this direction have already brought, a few years ago, to the creation of a new CTC machine with innovative features, thanks to a rotary transposing device. This machine, known as TH5.E in its current release, has heavily enhanced the ergonomy standard and the production quality of the transposed cable.
 
The new invention, now being patented, goes beyond this, introducing and additional motion in the machine, that creates a synchronous folding of the enameled strips during the transposing process.
 
The machine is called TH5 Synchro, a name given by this new operating principle, and completes the productive range of the "bigger sister". This machine is equipped with 4 servo-motors, thus much more sophisticated in terms of control. It is currently being tested in the laboratory of Proteco. The first results confirm the expectations. Soon it will be launched in the market.
