Fire-resistant cables are used in high-rise buildings, subways, power stations, and other critical locations, providing fire-retardant properties in environments. In addition to transmitting power at the rated working voltage of 0.6/1KV, these cables can maintain safe operation for a certain period during a fire. They can continue to operate safely for three hours under the intense heat of flames reaching 950-1000 degrees Celsius. This significantly enhances the safety coefficient of fire-resistant cables, providing valuable time for fire rescue efforts.
