摘要：

The article presents investigations into dependences of direct-current conductivity of dampness-soaked pressboard on the dampness level and temperature of the samples. Conductivity activation energy has been determined. It has been found that the conductivity is realized by hopping exchange of electrons between potential wells formed by water molecules in the amorphous cellulose structure. On that basis, theoretical dependences have been determined. They accurately describe the experimentally obtained dependences on the water content and temperature. (Electron hopping and DC conductivity of dampness-soaked paper-oil insulation of high voltage transformers).
