fire retardant cable is a specially designed cable that can maintain electrical signal transmission and power supply functions in the event of a fire. It has flame retardant, high temperature resistance, and fire resistance properties, and is commonly used in high-temperature environments, fire risk areas, emergency evacuation routes, and important facilities.
The flame resistant cable adopts special materials and design, which can automatically extinguish the fire source in case of a fire, or limit the combustion to a local area without spreading, and protect various other equipment to reduce the losses caused by the fire.
What is the difference between fire resistant electrical cable and flame resistant cable
The structural materials are different
Flame retardant cables are mainly made of flame-retardant raw materials, with an outer layer of flame-retardant sheath and fillers made of flame-retardant materials. The flame retardant principle is achieved through the flame retardant effect generated by halogen materials, which lowers the temperature by releasing water to achieve the purpose of extinguishing the flame.
The fire retardant cable is composed of a conductor and insulation layer, with a fire-resistant layer added in the middle. Its fire-resistant principle is to ensure that the cable can maintain normal operation for a certain period of time during a fire through the fire-resistant and heat-resistant properties of mica materials.
The cost is different
Due to its higher safety and reliability, fire rated cables have much higher production material or process costs than flame retardant cables.
Different functions and purposes
The main function of a flame retardant cable is to delay the spread of flames along the cable, preventing the fire from spreading. Under specified experimental conditions, after the sample is burned, the spread of the flame is only within a limited range, and the residual flame or burn can extinguish itself within a limited time. The flame retardant cable is suitable for environments such as homes, shopping malls, factories, etc. It may be burned out and unable to operate in the event of a fire, but it can prevent the spread of the fire.
A fire rated cable can maintain normal operation for a certain period of time under flame burning conditions, ensuring the integrity of the circuit. It is 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.
In short, fire rated cables and flame resistant cables have an irreplaceable position in the field of security, and their wide application and diversity require us to consider multiple aspects when choosing and using them. Only by fully understanding the basic concepts, classifications, application scenarios, and selection principles of fire rated cables and flame resistant cables can we better ensure the safety of life and property.
