Torsion Test Machine

The Torsion Test Machine determines the flexibility of any type of cable under torsional stress conditions (electrical conductors as well as fibre optic cables).

  • Suitable for temperatures from  -45 °C to +85 °C.
  • The capacity of the cables to be inspected is tested during axial torsion.
  • During the test cycle the cables are checked by one external measuring system. 
  • If a failure occurs, the system records the time and angle, without interrupting the machine operation (this option can be altered according to the requirements). 
  • On completion of the test cycle, a test log listing all the failures ocurred can be exported. 
  • The failure log in the display registers 100 events at a time, up to 50,000 events can be stored internally. 
  • All adjustments are carried out using the touch screen on the control panel.
  • The system was realized utilizing a digital servo drive, a brushless servo motor with planetary gearbox, as well as an industrial PC with customer-specific software.

This machine can test 6 cables simultaneously!
