Discussion on the difference between flame-retardant and fire-resistant cables in Xinchi Cable

1. Flame retardant cables and fire-resistant cables are both within the scope of GB/T19666-2019 standard management, which means that flame retardant cables and fire-resistant cable products must meet the relevant requirements (mainly referring to performance) in GB/T19666-2019 standard.

2. Explanation of flame retardancy: The sample is burned under specified test conditions, and after removing the fire source, the spread of the flame on the sample is only within a limited range, possessing the ability to prevent or delay the occurrence or spread of flames.

3. Explanation of fire-resistant cables: The characteristic of the specimen being able to operate continuously under specified conditions when burned under a specified source of fire and time.

4. The essential difference between the two: Flame retardant cables use flame retardant fuels, and during production and manufacturing, the characteristics of preventing or delaying the occurrence or spread of flames are reflected in the flame retardant materials, just like ordinary cable processes. When encountering flames or fires, they can only play a role in preventing, delaying, and spreading, not necessarily preventing combustion; The fire-resistant cable uses mica tape wrapped around the surface of the conductor. When the cable burns, it should not form a short circuit and can continue to be powered for a certain period of time. In the event of a fire, the fire-resistant cable, due to its continuous power supply, can better demonstrate its unique advantages in safe evacuation and maintaining the operation of some equipment.
