Aging Properties of Insulation Coating for High and Low Voltage Electric Wires

Abstract

The purpose of the paper is to clarify the deterioration characteristics of the insulating coating for electrical wire. In order to make a database for the mechanical strength and insulation performance of the insulating coating installed in actual field, existing removal insulating wires are randomly selected and tested based on JIS testing standards. Based on the developed database, the relationships among the mount of insolation, the period of service, and the deterioration performance of the insulating coating are analyzed using appropriate hypothesis testing. As a result, the standard deterioration characteristics with aging are quantified for each insulation coating type of electric wire.
