What is the difference between fire-resistant cables and flame-retardant cables?


Fire-resistant cable

Fire resistance refers to the ability to maintain a certain period of operation in the case of flame combustion, that is, to maintain the integrity of the circuit. This type of cable has a certain time power supply capability in the flame.


Flame retardant cable

Flame retardant refers to retarding and delaying the spread of flame along the wire and cable, so that the fire does not expand. This type of cable has self-extinguishing performance after fire.


Main difference between fire-resistant cables and flame-retardant cables:

1. Fire-resistant cables can maintain normal power supply for a period of time in the event of fire, but flame-retardant cables do not have this feature.

2. The principle of annoying cable and flame retardant cable are different. The flame retardant principle of halogen-containing cables relies on the flame retardant effect of halogen, and the flame retardant principle of halogen-free cables relies on the precipitation of water to reduce the temperature to extinguish the flame. Fire-resistant cable relies on the fire-resistant and heat-resistant characteristics of mica material in the fire-resistant layer to ensure that the cable will work normally in the event of a fire.
