Fire resistant cables are cables that can maintain safe operation for a certain period of time under flame combustion conditions. Fire resistant cables are widely used in places related to fire safety and firefighting, such as high-rise buildings, underground railways, underground streets, large power stations, and important industrial and mining enterprises.
Characteristics of fire rated electrical cable
Compact structure: The core arrangement of the fire rated cable is compact, not easy to loosen, and convenient for installation and maintenance. The conductor is made of high-purity oxygen free copper, and there is a fire-resistant tape between the copper conductor and the insulation. In the event of a fire in the fire rated cable, it can ensure that the fire retardant cable works for a period of time and strive for escape time.
Excellent flame retardant performance of fire resistant electrical cable: The insulation and sheath layers of the fire retardant cable are made of flame-retardant materials, which can effectively prevent the spread of flames.
Good high-temperature performance: The insulation and sheath materials of fire-resistant cables have undergone special treatment, which can maintain good electrical and mechanical properties in high-temperature environments.
The safety performance of fire retainer cables: Fire cables have high safety performance and can continue to supply power in case of fire, providing power support for important facilities such as emergency lighting, alarm systems, and firefighting equipment. It can also reduce the threat of fire to personnel and property, and improve the emergency response capability for fire accidents.
Fire rated cable is widely used in buildings, transportation, petrochemical industry, ships, subways, nuclear power stations and other places. The use of fire-resistant cables can improve the safety and reliability of electrical systems, protect the safety of personnel and property, and reduce the impact of fire accidents on society.
Precautions for choosing a fire retainer cable
Choose the appropriate type based on the usage environment: Different types of fire retainer cables have different characteristics and applicable locations, and the appropriate type should be selected based on the usage environment.
Consider the convenience of installation and maintenance: When selecting fire-resistant cables, the convenience of installation and maintenance should also be taken into account. Cable products with compact structure, easy installation and maintenance should be selected to reduce engineering and maintenance costs
Consider cable cross-section and voltage level: When selecting a fire rated electrical cable, its cross-section and voltage level should be taken into account to ensure that it meets the usage requirements. At the same time, attention should also be paid to its electrical performance parameters such as current carrying capacity and short-circuit withstand capacity.
Choose fire-resistant cables that meet the standards: When selecting fire rated electrical cables, cable products that meet national standards should be chosen to ensure reliable performance. For example, the fire rated electrical cable in Australia adopts the AS/NZS 3013 fire rated cable standard.
In short,fire-resistant cables have an irreplaceable position in the field of fire safety, and their wide application and diversity require us to consider multiple aspects when selecting and using them. The use of fire-resistant cables can improve the safety and reliability of electrical systems, protect the safety of personnel and property, and reduce the impact of fire accidents on society.
