Abstract :
Organic insulations compose. of parer or cloth base with phenolic or black asphaltic varnish impregnant are shown by extensive tests to have an aging rate in air dependent on the insulation thickness. A change in insulation thickness from that representative of turn insulation to that used for a major voltage barrier may increase its useful life in air by as much as ten times if in a dry atmosphere. `Iιe corresponding change in temperature class for a specific number of hours of life in air may be of the order of 30 C to 50 C for this change in thickness, under the same favorable conditions.
