Mineral insulated cable (MI cable) is a cable with a copper conductor core wrapped in a copper sheath and magnesium oxide powder as an inorganic insulating material to isolate the conductor and sheath. The mineral cable can become MICC cable (Mineral Insulated Copper Clad Cable) or MI cable (Mineral Insulated Cable).
1.Cable conductor: it is made up of stranded copper wires, with favorable flexural property.
2.Insulation layer: it adopts high-temperature resistant inorganic insulating materials
3.Copper sheath: copper materials, through special machining, with favorable flexural property, used as PE wire.
4.Outer sheath: it is made of plastic materials of low-smoke non-toxicity, with favorable corrosion protection.
Huadong mineral insulated cables have the advantages of high-temperature resistance, large current carrying capacity, corrosion resistance, smokeless and non-toxic, anti-electromagnetic interference, long service life, economy, and environmental protection. It is currently the safest and most environmentally friendly fireproof cable with high-cost performance. It is suitable for emergency lighting systems and fire alarm systems in the oil, natural gas, and petroleum industries, airports, and power and control circuits, and provides circuit integrity of 950°C.
PRODUCT STRUCTURE
Conductor: The conductor is made of the first high-quality annealed copper in accordance with GB/T3956.
Insulation layer (magnesium oxide): high temperature resistant, non-combustible inorganic magnesium oxide powder.
Metal sheath: Use high-quality annealed copper as the sheath.
Outer protective layer (optional): when there are requirements for corrosion protection, identification or aesthetics, a plastic coat can be used (halogen-free low-smoke coat is recommended).
Standard: GB/T34926; IEC60702; BS6387:1994; GB/T13033.1.2-2007, etc.
