STANDARDIZATION OF MAGNET WIRE (TWO TYPES) FOR USE AT 500 C (932 F)
Abstract
Firing techniques require that fine wire be fired in a vacuum in order that the wire conductor not be affected by oxidation. The firing cycle for larger sized wires is done in air with 5 to 30 min exposures at 500 and 675 C with breakdown strengths of 1000 v/mil. The initial physical properties of the enameled wire as well as the shelf aging problem can be improved to acceptable levels by proper choice of resin and a graduated reduction in glass content. Moisture-proofing of coils depends on the continuity of a treating glass applied after a coil has been fired. Both fiber-served and enameled wire have been made on a semi-production scale by semi-skilled personnel utilizing only standard methods and procedures. (Author)
