Abstract
The invention discloses a manufacturing method of a polyvinyl acetal enameled NbTi/Cu superconducting wire. The superconducting wire takes a polyvinyl acetal paint as a paint for enameling, and a NbTi/Cu superconducting wire as a wire core. The method comprises an enameling process at a softening furnace temperature of 220-400 DEG C and a baking furnace temperature of 250-430 DEG C. The inventive method employs a polyvinyl acetal paint as an insulating paint, to ensure no cracking or pulverization of the enameled film at 269 DEG C below zero, and guarantee the insulation property of the enameled film, so as to ensure normal use of NbTi/Cu superconducting enameled wire at 269 DEG C below zero and realize superconducting performance.
