Product Mode： Fixed mode of products： Test Speed： Number of tests： Equipment size： Description: The wire torsion testing machine is specifically designed to test the torsional strength of various metal wires and the number of times the paint film of enameled wire can withstand torsion. The testing method involves clamping both ends of the test sample with one end fixed and the other end continuously twisted back and forth until the test sample breaks or the paint film of the enameled wire peels off, exposing the conductor. The number of torsion cycles is recorded. The wire winding + torsion testing machine complies with both GB/T4909.4-2009 and GB/T4909.7-2009 standards.
