Studies of selected properties of high-temperature superconducting tape 2G HTS SF series - the example: tape SF12050

摘要

Purpose: In presented paper were characterized selected properties of high-temperature superconducting tape 2G HTS SF series - the example of the tape SF12050. Design/methodology/approach: As part of the study smples of tape SF12050 were made. At first made to measure of chemical compsition and compared with manufacturer's information about that kind of tape. Second step of researcher were research about adhesion of the individual layers of SF 12050. After then research was made about tensile strengtht what is the justification utility, as these tapes are subjected to tension at the time of their formation and winding on the transformer core. Findings: As a result of research obtained information on the chemical composition, scratch resistance, adhesion of coating on the tape and about tensile strength. On the last step studies were conducted about critical currents - Ic. Research limitations/implications: These results allow to identify the suitability of these tapes for use on a wide scale - in particular, the winding of the transformer cores. Originality/value: On the basis of studies have demonstrated applications for which the tape may be used SF 12050. Given its properties - scratch resistance and tensile strenght reistance, and information about critical current, was indicated best use of that tape for trnasformers production.
