High voltage breakdown (HVbd) tests was carried out to investigation electrical properties of high temperature MgO-ZrO2 insulation coatings on long-length stainless-steel 304 (SS) tapes under various pressures at room temperature (298 K) and liquid nitrogen temperature (77 K) for applications of HTS/LTS coils and magnets. Solutions are prepared Mg and Zr based precursors and insulated on SS substrates using reel-to-reel sol-gel technique. Thicknesses of coatings (7 and 12 m for 4 and 8 dips) and stycasted ribbons were determined by using Environmental Scanning Electron Microscope (ESEM). HVbd and dielectric constant of ribbons have been presented graphically. |
