The difference between fire resistant cable and flame retardant cable

The main difference: Fire-resistant cable can maintain normal power supply for a period of time in the event of a fire,but flame retardant cables can’t.

Fire-resistant cables are classified into Class A and Class B. Class A is better than Class B.

Class B cable can withstand combustion for at least 90 minutes in a flame at 750 ° C ~ 800 ° C and rated voltage, without cable breakdown (that is 3A fuse does not blow)

Class A cable can withstand combustion for at least 90 minutes in a flame at 950 ° C ~ 1000 ° C and rated voltage, without cable breakdown (that is 3A fuse does not blow)

Flame-retardant cable is a kind of excellent performance in fire-resistant cable. It is made of copper core, copper sheath and magnesium oxide insulation.

Flame-retardant cable is a good fire-resisting cable, and can work for a long time under high temperature of 250 °C. It also has the characteristics of explosion-proof, strong corrosion resistance, large current capacity, radiation resistance, high mechanical strength, small volume, light weight, long life and smoke free.
