FIELD: electricity.
SUBSTANCE: hydrophobic organosilicic compound for electric insulating structures is made on the basis of organosilicic compositions of cold hardening. The compound contains silicon low-molecular rubber, a filler, and also a hardener or a catalyst. The compound in vulcanised condition is characterised by the value of the edge angle of wetting from 60° to 179°, tracking erosion resistance at duration of tests making at least 500 hours at working voltages of 6-750 kV, and also with arc resistance characterised with arc current value of at least 100 mA with duration of effect of at least 600 s.
EFFECT: increased reliability and higher service life of a hydrophobic electric insulating coating on the basis of a compound, which is provided by composition and ratio of compound components and specified operating properties of a coating in vulcanised condition.
