Purpose: The paper deals with the determination of the impact and the possibility of heat treatment in order to improve the properties of YBa2Cu3O7-x- YBCO 2G HTS high-temperature superconducting tapes. Design/methodology/approach: Test samples of SF12050 superconducting tape, subjected to heat treatment - annealing in the temperature range of 450-1000°C. Two types of cooling were used on the air and with the furnace. Thus prepared samples were subjected to differential scanning calorimeter DSC - TG NETZSCH STA 409C.Results:The analysis was also subjected to the influence of temperature on the consistency of the protective layer with the other components of the tape, and a mechanism for destruction of the tape as a result of the impact of elevated temperatures. The paper also contains images of selected sections of the SF12050 superconducting tape which were preheated in the temperature range of 450-1000°C. Originality/value: Research carried out in the context of the article, made it possible to trace the influence of temperature on the destruction of superconducting tapes. Those studies show the destructive effects that may occur when using the type of tape, in particular as regards their application in the form of windings in transformers. Detailed knowledge of the thermal degradation mechanism of superconducting tapes, may lead to a response on how to modify them in order to avoid the devastating effect of temperature during operation.
