Fireproof cable is also called mineral insulated cable and magnesium oxide cable.
It is copper core copper sheath cable with mineral material magnesium oxide powder as insulation. Mineral insulated cable is composed of copper conductor, magnesium oxide and copper sheath two kinds of inorganic materials.
Magnesium oxide fire cable definition
Fireproof cables are all using inorganic (copper and magnesium oxide powder), it itself does not cause fire, could not burn or fuel, as a result of the copper melting point is 1083 ℃, magnesia melting point is 2800 ℃, so this kind of cable can be close to the melting point of copper fire cases continue to maintain the power supply, is a real sense of fire retardant cable.
And can pass BS6387C, W, Z test.
Magnesium oxide fire cable structure
Fireproof cable is a cable with annealed copper as conductor, dense magnesium oxide as insulation and annealed copper tube as sheath. When necessary, a layer of plastic outer sheath is extruded outside annealed copper sheath, and a layer of low-smoke halogen-free sheath can be added outside when it is required to be smokeless and halogen-free.
Meishen is the world's leading producer of magnesium oxide, Magnesium oxide is an oxide of magnesium, an ionic compound. It is a white solid at room temperature. Magnesium oxide exists in the form of periclase in nature and is a raw material for magnesium smelting. Magnesium oxide is white or light yellow powder, odorless, tasteless, this product is insoluble in water and ethanol, melting point 2852 ° C, boiling point 3600 ° C, magnesium oxide has high refractory insulation properties. It can be converted into crystal by burning at a temperature above 1000 ° C. If it rises above 1500 ° C, it will form a burnt magnesia or sintered magnesia.
Magnesium oxide can be used in the manufacture of metallurgy, smelting, advanced magnesia bricks, refractory materials and moisturizing materials. It is also widely used in rubber, rubber sheet, rubber products, pharmaceutical industry, food industry, plastic sheet accelerator, glass fiber reinforced plastics and Surface coating of silicon steel sheet, paper production, steel ball polishing, leather treatment, insulation materials, grease, dyes, ceramics, desiccant, resin, flame retardant, etc.
Hebei Meishen Chemical Technology Group is the main magnesium oxide producer in the world. It is also the largest magnesium salt producer in China and has won the ISO9002 quality system certification. It also has GMP-Certification.
With rich experience in the research, development, production, management and operation of magnesium oxide products, Meishen Group has always attached great importance to the research and development of new products and strict requirements on product quality. Meishen has a high-level sales team. The business covers more than 20 countries and regions around the world. It is widely welcomed by new and old customers.
