This paper considers a high-contrast, two-component composite 
of random structure, for whose simulation a two-dimensional network 
model is used. The dependence of the medium conductance on the volume 
content and composition of the filler that is characteristic of percolation 
theory has been obtained: up to some volume content, the effective 
conductance is small and then it grows rapidly. The results are based 
on statistical modeling (solving a large number of problems at various 
random distributions of inclusions and with subsequent statistical 
processing).
