To research the magnetic field interference on cables nearby three‐phase air‐core reactors and the shielding effect of different materials, this study analysed the influence on spatial magnetic field by using high‐conductivity materials and high permeability materials after the basis of three‐dimensional electromagnetic simulation model, and analysed the causes. Furthermore, the induced voltage in different shielding methods is calculated and discussed by using magnetic vector potential resulted from the finite element method. From the result, to achieve a satisfying effect, the shields under three‐phase reactors need connect when using high permeability. Moreover, a large number of magnetic leakages on the edge of shield can aggravate the magnetic field interference in surrounding areas. Therefore, the distribution of onsite cables in substation need to be considerate when using high permeability.
