Thermal Aging Studies of Encapsulated Motorette Insulation Systems

摘要

Thermal aging studies were conducted on four 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 138C and the Class B system from 130 to 150C. It is recommended that the encapsulated insulation systems studied be rated thermally Class B. Work is under way on determining how long encapsulated systems will remain sealed from a hostile environment. (Author)
