Structural principle: Mineral insulated cables are composed of mineral material magnesium oxide and metal material copper, and the magnesium oxide insulating material is highly compacted in the seamless copper sheath, forming a dense body together with the core and the sheath. The melting point of magnesium oxide insulation material is as high as 2800°C. Below this temperature, its insulation performance will not change significantly, while the melting point of copper is 1083°C. As long as the melting temperature of copper is not reached, the cable will not be damaged and can still continue to work. run.
Fire resistance: The fire resistance of mineral insulated cables meets the fire resistance time of 950 °C and 180 min specified in the product standard. Many fire scenes have also fully proved that after the fire, among all the cables, only the mineral insulated cables are still intact.
High temperature resistance, no aging: Mineral insulated cables can be used continuously for a long time at 250 ℃, with a life span of more than 250 years. Since the cables are all composed of inorganic materials, they are extremely difficult to age, and will not cause and spread fire, which is an essential Safe product.
Smoke-free, halogen-free, radiation-resistant: In the case of overload or fire, the mineral insulated cable itself will not release any harmful gas and smoke, and the light transmittance reaches 100%, which is very important for ensuring the safe evacuation of personnel under fire conditions It is very important; it can also ensure that houses and equipment are not damaged by acid gas. It is an environmentally friendly cable. Since the entire structure of the cable is made of inorganic materials, there will be no change after irradiation, so it is especially suitable for the environment of nuclear radiation; also due to the structural characteristics of the seamless copper sheath of the cable, it can provide very good shielding for electromagnetic induction Effect.
