effect of fire-resistant carbonate coating for electric cable safety

Electrical fires occur in electrical power lines, wires, circuit breakers, and on other electrical components. the electrical wiring is the core area in power transmission and is of great importance. the carbonates of alkali and alkaline earth metals to combat the circumstances of an electrical fire with a single standalone metal carbonate or as a combination of two or more carbonate mixtures for determining the ideal mixture combination along with % increase in the temperature at which the electrical cables fires started as well as the % increase in theprolongation time of the electrical cables to catch the fire is studied in this work. the carbonate materials were applied in the inner covering of the electrical cables. application of these self-extinguishing chemicals as fire retardants produces carbon dioxide emissions as a gas blanket on heating. this co2 release from wire cables increases its ignition temperature and further helps to prolong the time for the cables to catch fire. the study optimal results for 3/29 wire gauge with an applied combination mixture of sodium carbonate and calcium carbonate in a 1:1 ratio by weight revealed a % increase in the ignition temperature and the % increase in time to ignite the electrical cables as 38.39±0.48% and 21.86±8.0% respectively. in addition, for the 7/29 wire gauge cable in a similar ratio, the mixture combination of sodium carbonate and magnesium carbonate shows respective results as 13.02±1.7% and 54.5±1.10% increased.
