Low smoke halogen free cable and mineral insulated cable are two different types of cables; The editor will share with you a comparison between low smoke halogen-free cables and mineral insulated cables in terms of materials, characteristics, voltage, usage, and price.
1. Comparison of Cable Materials
Low smoke and halogen-free cable: rubber insulation without halogen (F, Cl, Br, I, At) and environmental substances such as lead, cadmium, chromium, mercury, etc
Mineral insulated cable: There is a tightly compacted magnesium oxide insulation layer between the magnesium oxide (inorganic material) sheath and the metal wire core.
2. Comparison of cable characteristics
Low smoke halogen-free cable: It does not release halogen-containing gases during combustion, has low smoke concentration, and allows for a working temperature of up to 150 ° C. Through irradiation crosslinking process, the cable achieves flame retardant effect, and is an environmentally friendly cable that complies with the European Union.
Mineral insulated cable: It does not burn or support combustion, does not produce harmful gases, can maintain normal power supply for 3 hours at a flame temperature of 1000 ° C, has strong electrical stability, long service life, and high current carrying capacity.
3. Comparison of cable rated voltage and usage
Low smoke and halogen-free cable: suitable for places with rated voltage of 450/750V and below, requirements for halogen-free, low smoke, flame retardant, and high safety and environmental protection. Densely populated areas such as high-rise buildings, stations, subways, airports, hospitals, libraries, family residences, hotels, hospitals, office buildings, schools, shopping malls, etc.
Mineral insulated cables: Suitable for places with rated voltage of 0.6/1KV and below, and high requirements for flame retardancy, fire resistance, flexibility, and high temperature resistance. Places such as petrochemical industry, airports, tunnels, ships, offshore oil platforms, aerospace, steel metallurgy, shopping centers, parking lots, etc.
4. Comparison of cable prices
Low smoke and halogen-free cables are about 10% -20% more expensive than regular cables.
Mineral insulated cables are about 1-5 times more expensive than regular cables.
In summary, there is no comparability between low smoke halogen-free cables and mineral insulated cables. The two are two different types of cables with different characteristics and advantages; Comparing two different levels of cables is meaningless.
