EFFECT OF ELECTRICAL INSULATION MATERIALS ON PROTECTIVE METAL FINISHES UNDER CONDITIONS OF HEAT AND MOISTURE.

Abstract

An investigation was made of the effects of certain AIEE, Class O(90C) and A(105C) electrical insulation materials on protective metal finishes. Sleevings, tapes, varnishes, insu lated wires, and insulation paper were evaluated in contact with and in confined close proximity to bare steel, uncoated aluminum, anodized aluminum, and cadmium and zinc (with and without chromate treatment). Temperatures and initial relative humidities utilized were 160=2F and 100% R.H., and 200=2F and 50% R.H. Sleeving materials in general were the most corrosive and insulated wires the least corrosive insulation material. Zinc with and without chromate treatment was most susceptible to corrosion by the insulation materials tested and anodized aluminum the least affected metal. The greatest amount of corrosion occurred at a test temperature of 200F. (Author)
