Mineral insulation cables are referred to as MI cables. When used as a wiring, domestic habits are called magnesium oxide cables or fire -proof cables.It is a copper -core copper -cubes cable with magnesium oxide powder for mineral materials. The mineral insulating cable consists of two inorganic materials: copper conductor, magnesium oxide, and copper cover.
Mineral insulation cable standard
The types and standards of commonly used rigid mineral insulation cables: According to the standard of mineral insulation cable, rigid mineral insulation cables can be divided into light rigid mineral insulation cables, and heavy rigid mineral insulation cables.The standards of division are divided according to voltage. Among them, the AC voltage used is 500 volts and its below 500 volt is light.It is heavy if the AC voltage is 750 volts or 750 volts.Power cables mainly include: BTTZ heavy copper core copper-cord cup mineral insulation cable, BTTVZ heavy copper cinemal cubic cubic cubin p-chloride outer crickets, mineral insulation cable, LSF-BTTZ heavy copper core, low-smoke halogueInsulation cable.Control cables are mainly: BTTQ light copper-core copper cupped jacket mineral insulation cable, BTTVQ light copper core copper cupcopyclene outer cricket mineral insulation cable, LSF-BTTQ light copper cadron cubes low smoke and halogen-free lymite mineralsInsulation cable.Copper -core copper clocks in insulation in mineral insulation cables are mainly magnesium oxide oxide oxide, mainly composed of copper conductors and magnesium oxide and copper cases: two inorganic materials.
Mineral insulating cable load flow
Because the actual normal use temperature of mineral insulation cables can reach 250 ° C, IEC60702 stipulates that the continuous operating temperature of mineral insulation cables is 105 ° C. This is considering the needs of terminal sealing materials and safety. Even so, its load is far more than other cables.Because magnesium oxide powder has a better thermal conductivity than plastic, the same working temperature, the load volume is greater.For lines above 16mm2, one cross -section can be reduced. For places that do not allow people to contact, two sections can be reduced.
