    As a result of experimental and theoretical progress over the last decade, our understanding of water treeing is approaching the molecular level at which the fundamental chemical nature of the phenomenon will be revealed. Further effort is required to complete the picture. The analytical techniques employed to date indicate that the water tree region contains a wide range of chemical species, with...

    Cellulose serves as raw material for various electrical insulating materials, for instance, insulation paper and electrical pressboard. The practical application of these insulating materials involves situations where a reduction in strength may occur due to impurities, structurally inhomogeneous features, and ageing of the cellulose, or by boundary layer phenomena. The insulating capacity is rest... View full abstract»
