GB4909.4-2009 • GB4909.7-2009 Bare Wire Mandrel Winding and Torsion Tester

Product description: Bare wire mandrel winding and torsion tester is used for copper rods, aluminum rods, steel wires mandrel winding and torsion tests under the specified torsion speed; as well as test of broken resistance strength and torsion frequency performance for different metal wires, and toughness and adhesion performance for overhead wire and galvanized steel wire. Test method is to clamp the both ends of the specimen, one end is fixed and the other end 360º continuously twisted Standards: • GB4909.4-2009 • GB4909.7-2009 Technical parameters: • Torsion specimen diameter range: copper rod less than φ8mm, steel wire less than Ф3mm • Torsion speed range: (10, 30, 60)r/min, adjustable • Grip space: 0~500mm • Grip movement: chuck type • Winding specimen diameter range: aluminum wire: Ф3mm-6mm, use the core rod for test, those of diameter are less than Ф3mm, we suggest to wind them manual; steel wire: less than Ф4mm • Core rod range: Ф3mm, Ф4mm, Ф5mm, Ф6mm, Ф8mm, Ф10mm, Ф12mm, Ф14mm, Ф16mm, Ф18mm, Ф20mm • Weight: 500g×1, 1000g×1, 2000g×4 • Hook: 587.5g Specifications: • Overall dimensions: 1400mm×500mm×1500mm • Power supply: AC 220V 50/60Hz 4A
