What is the durability of an electric cable in an electrical installation?

The cables are designed to last, under normal conditions, over 25 years. During normal use, situations can occur that cause the system to overload, overheating the cables and reducing their useful life. Studies indicate that, at every 5 ° C temperature in the operating conductor, above the maximum limit allowed for the cable, it has its life reduced by half.
To minimize this problem, and to avoid major damage, conductors have been developed that are up to 20% more temperature resistant, withstand, in the event of overloads, double the time of conventional cables.
These cables, which withstand an operating temperature of up to 85 ° C, reduce the occurrence of short circuits, the ones most responsible for electrical accidents, making circuits safer.
