Experimental studies were conducted to simulate cabling in a fire risk. Cables AVVG 3h25 an x16 gorizonatlno were laid on trays and covered with a layer of sawdust. When laying in three rows and 14 cables in a number of cable connection completely burnt out the entire length. At this speed were recorded: on the bottom row 0.00154 m / s, on average, 0.00167 m / s, the top .00170 m GOST 5960-72 “Plasticized polyvinyl chloride insulation and protective coverings of wires and cables” was developed and put into effect from 1 January 1974, has 9 enhancements . Since 1991, work on introducing technical changes to the GOST 5960-72 were terminated. Further development and modification of existing brands were made out of flexible PVC in the form of technical specifications. From 1 July 2010 abolished the action of the Russian Federation GOST 6323-79 “The wires with PVC insulation for electrical installations. W “and GOST 16442-80,” Power cables with plastic insulation.
N “and put into effect GOST R 53768-2010” wires and cables for electrical equipment for a nominal Voltage 450/750 V, inclusive. TSP “and GOST R 53769-2010″ Power cables with plastic insulation for rated voltage of 0.66 1 and 3 kV. OTU. ” Impregnated paper insulation cable paper in accordance with GOST 23436-83 for insulation of power cables for voltages up to 35 kV grades K and the Commission are made from unbleached kraft pulp, KM mark – of unbleached kraft pulp for paper multi-cable..
