Mineral insulated cable is distinguished from fire resistant cable


There are also many types of cables, so what is the difference between mineral insulated cables and fire resistant cables?The biggest difference between mineral insulated cable and fire-resistant cable is that the cable structure is completely different, which determines the maximum temperature and duration of fire protection.Next I will introduce the specific differences and whether it can be laid together with the bridge.

Introduction to mineral insulated cable

Mineral insulated cables are non-combustible, smokeless, non-toxic and fire-resistant, usually composed of copper conductor, magnesium oxide insulation material, copper or copper alloy sheath, performance in line with the national standard "rated voltage 750V and below mineral insulated cables and terminals" GB/T13033 related provisions of the cable.Mineral insulated cable can be coated with organic material as the outer sheath. The outer sheath should meet the requirements of halogen free, low smoke and flame retardant.

Two, fire-resistant cable

Fire-resistant cable in the specified test conditions, wire and cable in the flame is burned in a certain period of time can still maintain the normal operation of the characteristics, that is, the ability to maintain the integrity of the wire and cable, this and flame retardant cable is also different.Flame retardant cable in the specified test conditions, the wire and cable is burned, in the removal of the fire source, the flame in the wire and cable spread only in a limited range and self-extinguishing characteristics, that is, has the ability to prevent or delay the occurrence or spread of the flame of the wire and cable.There is another kind of cable is a combination of the two called halogen-free low-smoke flame-retardant cable: the material does not contain halogen, the combustion product is less corrosive, the combustion produces less smoke and dust and light transmittance is high and has the ability to maintain the integrity of the fire-resistant wire and cable.

Three, mineral insulated cable and fireproof cable fire performance difference

1, mineral insulation cable fire performance requirements

Fire performance of mineral insulated cable

2. Fire-resistant cable fire performance requirements

Fire resistance of cable

Obviously, the maximum temperature of the mineral insulated cable should reach 950℃ and maintain normal power for 3 hours.The highest temperature of fire-resistant cable is 750℃, and it can keep normal power on for 90 minutes.

So according to the above point of comparison, we can see that mineral insulated cable and fireproof cable can be laid with the bridge frame, but it is best to add layer partition.Even so, mineral insulated cables and fire-resistant cables are slightly different, and the actual application should be considered as appropriate.
