Product introduction
1. Flexible mineral insulated cable is composed of copper stranded wire, mineral compound insulation, and mineral compound sheath.
2. Flexible structure, the main materials are made of inorganic materials, to make up for the structure of hard, easy to burn, toxic and other defects.
3. Fire resistance, large current load, impact voltage resistance, mechanical damage resistance, halogen-free non-toxic, explosion-proof, waterproof, corrosion resistance, long life, safety, overload resistance, high temperature resistance, low cost characteristics.
Mineral insulated cable, a copper sheath wrapped copper conductor core wire, and magnesium oxide powder as inorganic insulation material to isolate the conductor and sheath of the cable, the outermost layer can be selected according to the need for appropriate protective sleeve. Commonly known as MICC or MI cable. There is a similar cable with metal instead of copper sheath to wrap the core wire and insulation material, called mineral insulated metal sheathed cable
Mineral insulated cables are all composed of inorganic substances (metal copper and magnesium oxide powder), which will not cause a fire, it is impossible to burn or ignite, because the melting point of copper is 1083 ° C, and the mineral insulation layer is also a melting point above 1000 ° C. Therefore, this kind of cable can continue to maintain power supply in the case of fire close to the melting point of copper, and is a fire proof cable in the true sense.
Since the actual normal use temperature of mineral insulated cable can reach 250 ° C, IEC60702 stipulates that the continuous working temperature of mineral insulated cable is 105 ° C, which is taking into account the needs of terminal sealing materials and safety, even so, its current carrying capacity is far more than other cables, because mineral insulation has better thermal conductivity than plastic. So the same operating temperature, the carrying capacity is larger. For lines of more than 16mm2, one section can be reduced, and for places where human contact is not allowed, two sections can be reduced.
