Product Mode： Fixed mode of products： Test Speed： Number of tests： Equipment size： Description: The wire torsion testing machine is specialized in testing the breaking strength of various metal wires and the number of times the paint film of enameled wires can withstand torsion. The testing method is to clamp one end of the sample tightly and fix it in place, while continuously twisting the other end back and forth until the sample is twisted or the paint film of the enameled wire falls off, exposing the conductor, and recording its torsional resistance. The wire winding and torsion testing machine complies with both GB/T4909.4-2009 and GB/T4909.7-2009 standards.
