Construction Materials-Other Building Materials
The product is suitable for high-rise buildings, oil fields, power stations, electric power plants, mines, chemical industries, subways, and other scenarios that require high fire protection standards. It is also used as an emergency power supply, fire pump, and elevator communication signal system's standby cable. This product has flame-retardant and fire-resistant cable capabilities. Under direct flame exposure, it does not short circuit or break within a certain period (not less than 3 hours), ensuring continued power supply to maintain lighting and signal transmission, providing personnel with sufficient time for safe evacuation, and aiding in firefighting and reducing losses. 1.
