Enclosed is construction of fire-resistant electric cable with plastic insulation, intended for transmission and distribution of electrical energy and electric signals in stationary plants in operation on objects of diffusion nnoi danger with preservation of serviceability of at action of open flame in for 3 hours. With the aim of diffusion condensate operational characteristics of using fire-resistant cable has thermal barrier of each current-conducting conductor from slyudosoderzhashchei -based tape mica paper and mineral fabric from silica or basalt fibers or their mixtures, including modified oxides of rare or rare-earth metals, or semiconductor materials or their mixtures. New cable highly technological and has diffusion nnym quality and reliability.
