Compared with traditional wires and cables, the durability and reliability of mineral insulated fire-resistant cables are the most prominent. In addition, the mineral insulated fireproof cable has advantages in its fire resistance. The continuous working temperature of the mineral insulated fireproof cable is 250 ℃, and the power can be continuously supplied for 3 hours at 950 ℃ -1000 ℃. The normal melting point of copper is 1083 ° C. Due to these excellent properties of mineral insulated fireproof cables, it is very suitable for lines with a rated voltage below 1000V.
Mineral insulated fire-resistant cables also have large current carrying capacity, water, explosion-proof, corrosion resistance, high operating temperature, corrosion resistance, and overload protection, so their life is longer than traditional cables. These advantages combined make the mineral insulated fireproof cable have excellent fire resistance.
Whether in government departments, factories, or residential buildings, the safety of electrical wiring is very important. According to detailed statistics from relevant national departments, among various types of fires, fires caused by electrical lines account for more than 50%. Wires and cables are an important part of electrical circuits. Therefore, wires and cables must not only stabilize themselves, but also have the ability to resist external flame erosion. The mineral insulated fire-resistant cable is made of inorganic materials. The material used for the insulation is magnesium oxide. No open flame will occur when overloaded or short-circuited. Therefore, transmission lines composed of mineral insulated fire-resistant cables will not catch fire.
As for the external flame erosion, the mineral insulated fireproof cable has extremely strong fireproof performance. In addition, the mineral insulated fireproof cable should not cause toxic smoke gas for the reason of the flame, so as to ensure the normal starting of fire fighting equipment, fire extinguishment and the evacuation of personnel.
