The INTERNATIONAL WIRE press-welded shunts are made with an assembly of strips.

The terminals are manufactured according to the press-welding process.

This same process allows the solid reconstitution of the material which constitutes the terminals under the associated combinations of both pressure and temperature.

Consequently, the contact resistance between the strips does not exist any longer, same for the rooting up effect of the material at the time of machining, drilling or punching of the endplates.


All applications linked to power and supply production, furnaces, electrolysis.

Medium voltage electrical appliances (Switchboards – Circuit breakers – Inverters/converters)

Transformers – power distribution.

The range

  • Standard widths : from 20 to 200mm (other dimensions upon request).
  • Strip thickness : from 0.1 mm to 0.3 mm.
  • Shunt Thickness : as from 10 mm up to 40 mm (other dimensions upon request).


  • The press-welded process enables to preserve the physical characteristics (electrical – mechanical and thermic) of the strips assembly.
  • Press-welding :
    • Shaping of the shunts.
    • Surface treatment of the terminals: tinned or silvered with DALIC process.
  • BT press welding :
    • Additional silvered strip without any residual chemical rejection during the exploitation.
    • Limitation of the temperature elevation during the welding process in order to prevent the oxydation of the raw material on the flexible part of the shunt together with contact endplate.
