Polyimide film has been used as an insulation material in the excitation winding of the high temperature superconducting motors. The existence of surface charge has a great influence on the breakdown characteristic. Direct fluorination is an effective method of polymers surface modification which can improve the electrical properties of original material. Therefore, it is necessary that the surface...
High temperature superconducting (HTS) cable has now reached the stage where their application in power systems is in the process of being implemented. Polyimide film has been used as an insulation in HTS cable systems with the advantages of low temperature resistance, good mechanical properties and excellent dielectric properties. Due to the organic properties of polyimide, the breakdown of the films...
With the emergence of superconductor technology, high temperature superconducting (HTS) power devices are quickly being developed. Among them, the HTS cable is receiving considerable attention and application in power systems due to high capacity and low loss. To develop a HTS power cable system, the terminal technology is essential component. The HTS cable terminations must withstand a temperature...
