High Precision DX8440 Wire Winding Torsion Tester

DX8440 wire winding torsion tester

Product Introduction: Mainly suitable for conducting torsion and winding tests on copper rods, aluminum rods, and steel wires at the specified torsion speed. It can also be applied to the twisting strength of various metal wires and the number of times the paint film of enameled wires can withstand twisting.
Test method: The test method is to clamp both ends of the test piece and fix one end in place, while continuously twisting the other end 360 º back and forth until the test piece breaks or the paint film on the enameled wire peels off, exposing the conductor, and recording its resistance to twisting.
Compliance with standards: Meet the requirements of GB4909.4-2009 and GB4909.7-2009 test standards.
