摘要：

The quench process of a multi-strand cable was investigated using the simplest system: two twisted wires. Several properties of the quench, such as the commutation of currents, the time scale, the resistance rate and the maximum voltage were determined experimentally or by calculation. Particular attention was given to the role of the cable length. Several samples with lengths varying from 1.5 cm to 12 m were made from an AC superconductor with CuNi matrix. In the experiment, the decay of the currents is measured after initiating a local normal spot in one of the wires. An important conclusion is that the quench propagation and stability of a cable depends on its length and can therefore be influenced by soldering it at certain intervals.
