Production area

The company PARTZSCH Spezialdrähte GmbH has become a significant business of the PARTZSCH Group. Whether it is the production or repair of motors, generators or transformers – our special wires meet every challenge. Through the close cooperation with engineers from development, engineering and production departments in the field of electrical engineering, we have gathered many years of experience and have the necessary know-how for the manufacture of high-quality wires. We produce rectangular wires in all standard dimensions with a variety of insulation types. Apart from the manufacture and insulation of rectangular wires we dispose of yarn-covering systems for round wires that allow finishing bare or enamelled round wires with different types of insulations.

With continuous quality controls performed by our advanced equipment and the ongoing monitoring through our test facility, we can guarantee the compliance with all customer-specific parameters. Our quality management system is certified according to DIN EN ISO 9001 and forms the basis for an individual customer service and the realisation of shortest delivery times.

Manufacturing of profile wires from bare wires

Range of services

With our machinery we are able to produce rectangular wires in the following dimensions:

  • Copper wires according to DIN EN
    • Width 3.35 – 30.00 mm
    • Thickness 1.00 – 7.00 mm
  • Round wires according to DIN EN
    • Diameters from 0.50 – 11.00 mm
  • Customized wire dimension on request

Range of services

After rolling the copper the structure becomes harder. However, in electrical engineering, a relatively high ductility is required. At the same time, this ductility is a quality feature of the manufactured wires. We can offer quality R200 according to DIN EN 13 601 to our customers. After consultation customer-specific limits can be realised (softer wires).

Machinery

In order to achieve the quality we use state-of-the-art machinery: 3 retort annealing lines, 6 cooling stations and an annealing furnace.

Range of service

We can offer wire enamelling for rectangular and round wires with various wire dimensions in a variety of thicknesses. The following dimensions of enamelled wires are available:

Rectangular wire:

  • Width 3.35 – 14.00 mm
  • Thickness 1.00 – 5.60 mm

Round wire:

  • Ø: 0.50 – 2.60 mm
Tape-covered wires

Range of services

Apart from wire enamelling we offer the tape-covering of rectangular and round wires in dimensions of width 3.35 – 25.00 mm / thickness 1.00 – 7.00 mm or diameter Ø 0.85 – 6.00 mm according to DIN EN with various additional insulating materials.

Machinery

All insulation types mentioned above can only be realised with the help of suitable machinery. For the production of film, Nomex and mica wires we can use 12 rectangular-wire and 12 round-wire taping machines. Another 4 machines are used for the production of polyimide film wires.

Range of services

Wires that are exposed to high levels of stress, vibrations, temperatures and variations in temperature are usually covered with yarn in different designs and materials. For instance, there are yarns made of glass fibre and so-called blended yarns (Daglas). The individual yarns differ in the number of single yarns, thus a variety of designs can be realised, depending on customer requirements, stress levels and field of use.

Machinery

For covering rectangular wires with yarn in the field of Daglas and / glass fibre insulation we have a total of 10 plants at our disposal.

Furthermore, there is the option of finishing bare or enamelled round wires with a variety of yarns or polyimide films in our yarn-covering machine for round wires.

The manufacturing is completed by the application of our tape cutting machines and the respective cross coil machines, used for mica material and glass fibre / Daglas. These machines enable us to respond flexibly to all our customers' needs.
