【Abstract】 This paper presents first the calculation of self and mutual inductances of a CD HTSC cable in case its return current that flows through shield is equal and opposite to the phase current in conductor as well as the design procedure for uniform distribution of a multilayer superconducting conductor and shield of CD HTSC cables.Current distribution in conductor and shield for several typical structures of CD HTSC cables is calculated and investigated to illustrate the influence of shield current on current distribution in superconducting conductor and shield of the CD HTSC cables.Calculation procedure of CD HTSC cables with current uniform distribution in superconducting conductor and shield is recommended to be the basis for design of CD HTSC cables.A complete computer program in this regard is available for practical application.更多还原
