A Fire Resistant Cable is a cable that can operate safely for a certain period of time in the event of a flame. China's ** standard GB12666.6 (such as IEC331) will be fire test divided into two levels, A, B,
Class A flame temperature is 950~1000°C, and the continuous fire time is 90min.
Class B flame temperature is 750~800°C, and the continuous fire time is 90 min.
During the entire test period, the specimen shall withstand the rated voltage rating specified by the product. Fire-resistant cables are widely used in high-rise buildings, underground railways, underground streets, large power stations and important industrial and mining enterprises in places related to fire safety and fire rescue, such as power supply lines and control lines for emergency facilities such as fire fighting equipment and emergency light.
Common fire-resistant cables in China are classified into Class A and Class B: Class B cables can withstand combustion for at least 90 minutes in flames and rated voltages of 750 ° C to 800 ° C without the cable being broken down (ie, the fuses are not blown). Based on the improvement of the refractory layer manufacturing process and the increase of the refractory layer, a Class A fire-resistant cable was developed, which can withstand combustion for at least 90 min in the flame at 950 ° C to 1 000 ° C and the rated voltage without the cable being broken down. (ie 3A fuse does not blow).
Class A Fire Resistant Cables have better fire resistance than Class B. In addition, the mineral insulated cable is a kind of excellent performance in the fire resistant cable. It is made of copper core, copper sheath and magnesium oxide insulating material, referred to as MI (minerl insulated cables). The cable is completely composed of inorganic materials to form a refractory layer.
