Abstract
By using Chebyshev polynomials approximate expressions for determination of radial and tangential components of magnetic field intensity on the surface of power cable steel armour are obtained. The increase of precision is obtained by choosing appropriate nodes of approximation. Obtained expressions for radial and tangential components are sufficiently correct for determination of behavior of mentioned com-ponents on the surface of of power cable armour.
