This tester is used to test torsion resistance of metal wire or rubber insulated cable. One end is fixed and the other is under continuous torsion till specimen breaks. The rotation can then be measured.
|Grips distance||200 mm, cable dia. >= 2.8 mm (steel wire)|
|150 mm, cable dia. < 2.8 mm (steel wire)|
|150 mm, cable dia. <= 1 mm (copper & lead wire)|
