Electrical properties of MgO-ZrO2 insulating coatings on different types of epoxies

The insulating coating of MgO-ZrO2 was coated on Stainless-Steel-304 (SS) tapes by reel-to-reel sol-gel process for investigation of electrical properties under various pressures at room temperature (298 K) and liquid nitrogen temperature (77 K) for HTS/LTS high field insert coil. Solutions were...
