FIELD: physics.
SUBSTANCE: invention relates to insulating element (1) having low electric conductivity and intended for electric insulation of electrical component in high-voltage range. Element (1) comprises natural fibres (2) and electroconductive particles (3) having nonconducting core (5) enclosed in electroconductive or semiconducting shell (6). Element (1) also contains cationic polymer (4), wherein the size of electroconductive particles (3) lies in range of 2–200 mcm, preferably in range of 2–100 mcm.
EFFECT: invention provides accurate adjustment of electrical conductivity of insulating element.
