The military electronic transformer and future insulation system requirements

With the above considerations in mind, our efforts to understand and characterize insulation systems should provide a better understanding of end of life capabilities. This development should allow a more proficient use of the older materials to meet the new requirements for specified reliability. Insulation system requirements for space and underwater ambients will, by necessity, have to await the results of additional exploratory work. As for trends in equipment for use in atmospheric ambients, needs have been demonstrated for such materials as: (a) An epoxy dip coating with electrical and mechanical characteristics equivalent to the epoxy moulding compounds. (b) A liquid dielectric with equivalent electrical and physical characteristics of transformer oil through the extended temperature range of 200-250°C. (c) A layer insulation with the electrical, physical, and mechanical characteristics of Kraft paper through the extended temperature range of 200-250°C.
