FIELD: textile, paper.
SUBSTANCE: impregnation of cellulose fibres consists of polyethylenimine. The electrical conductivity of the cellulosic material corresponds to the electrical conductivity of the transformer oil by magnitude order. The electrical conductivity of the cellulosic material is controlled by the choice of polyethyleneimine concentration.
EFFECT: improved resistance to breakdown of transformer insulation.
