Abstract :
Features of steady normal-zone evolution in the transverse and longitudinal directions of multi-strand region composed of superconducting composite and insulation are discussed. It is shown that allowance for a transient diffusion process in insulation does not practically change the results of quantitative description of the normal-zone kinetics in superconducting coil. The propagation of the normal zone in a layer structure of conductor and nonconductor parts is mainly affected by the thermal resistance of insulation.
