What are the properties and uses of mineral insulated cables?

I. What is the performance and use of mineral insulated cable? Mineral insulated cable is made of high conductivity copper as conductor, inorganic magnesium oxide as insulation, seamless copper tube as sheath, made by special technology. Due to the special nature of its materials and structure, the product has the electrical properties, mechanical properties, environmental performance and performance that cannot be compared with the machine cable (plastic cable). Fire, explosion-proof, waterproof, smoke-free, halogen-free, non-toxic, high temperature, corrosion resistance, radiation resistance, anti-electromagnetic interference, high current-carrying capacity, overload capacity, high mechanical strength, small size, light weight, long life, good grounding and other characteristics. Long-term use of bare cable temperature of 250 ℃, in 950 ~ 1 ℃ can be continuously powered 3h (standard 90min), a short period of time or very close to the melting point of copper 1083 ℃ work (magnesium oxide insulation melting point of 280 ℃). Used in important electrical engineering fields, such as hazardous areas: airports, oil depots, liquefied petroleum gas stations, chemical industry, coal mines, (nuclear) power stations, iron and steel smelting and shipbuilding, etc.; Important public facilities: satellite earth station, railroad wiring, alarm, fire, etc.; to ensure the safety of personal property places: historic buildings, hotels and guesthouses, high-rise buildings, museums, libraries, banks, hospitals, insurance, shopping malls, scientific research institutes and so on. Once laid, the cable can be used forever.
