Another very important issue, but that comes after installing the cables, is the durability that they may have. 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 its useful life. Studies indicate that, for every 5ºC of temperature in the conductor in operation, above the maximum limit allowed for the cable, it has its life reduced by half. In order to minimize this problem and even avoid further damage, conductors have been developed that are up to 20% more resistant to temperature, withstanding, in the event of overloads, twice the time of conventional cables. These cables, which withstand an operating temperature of up to 85ºC, reduce the occurrence of short circuits, the biggest responsible for electrical accidents, making the circuits safer.
