✦ Synopsis

The paper discusses the use of electrical sheets with particular emphasis placed on cryogenics transformers. Since the construction of cryoresistive transformers --and not superconducting ones --seems to be more likely, the anisotropy of resistivity and magnetoresistance of the transformer sheets were examined. It is pointed out that both the phenomenon of magnetocrystalline anisotropy and that of anisotropy of resistivity are encountered. Thus, while designing magnetic cores of cryo-resistive transformers it is necessary to consider a much greater range of anisotropy of the sheet core losses than in the case of oil transformers.
