Thermal Aging Studies of Encapsulated Motorette Insulation Systems

reportActive / Technical Report | Accession Number: AD0744951 | Open PDF

Abstract:

Thermal aging studies were conducted on four epoxy encapsulated insulation systems on motorettes to establish their thermal ratings. Encapsulation of Class A and B INSULATION SYSTEMS RESULTED IN UPGRADING THE class A system from 105 to 138 C and the Class B system from 130 to 150 C. It is recommended that the encapsulated insulation systems studied be rated thermally Class B.
