Mineral insulated cable

Product characteristics:
1. Fire prevention
Because all cables are made up of inorganic materials (metal copper and magnesia powder), it does not cause fire, can not burn or fuel. Because the melting point of copper is 1083, and the melting point of Magnesium Oxide is 2800, so the cable can continue to keep power under the fire of copper melting point, it is a real fire protection. Cable。 And it can be tested by BS6387 C, W and Z.
Test project
Two, large capacity and waterproof
Because the actual operating temperature of the mineral insulated cable can reach 250 C, IEC60702 specifies that the continuous working temperature of the mineral insulated cable is 105 degrees C, which is considered to the needs of the terminal sealing material and safety. Even so, its carrying capacity is far more than the other cables, because the magnesia powder has a better thermal conductivity than the plastic, so the same is the same. The working temperature of the sample is greater and the flow rate is greater. For a line above 16mm2, a section can be reduced, and two sections can be reduced to places where people are not allowed to contact.

Because the copper sheath used in the mineral insulated cable is a seamless copper tube, the sealing mud used by the terminal is also a high-tech product that can be soaked in the water for a long time, so the water molecules are completely blocked out, which is a real waterproof product.
Three, explosion proof and corrosion resistance
Explosion-proof characteristics: because the copper sheath used in mineral insulated cables is a seamless copper tube, and magnesia powder is tightly compacted, flammable gas, oil vapor, flame can not reach the electrical equipment connected with the cable, so the cable has the explosion-proof characteristics.
Corrosion resistance: because copper has good corrosion resistance, it does not need any additional protection in the normal environment. Under special environmental conditions, such as a strong corrosion to copper, a layer of PVC outer sheath is added outside the cable, so the cable has good corrosion resistance.
Four, mechanical damage, long life, no halogen-free nontoxic
Mechanical damage resistance: because the metal sheath of the cable has a certain strength and toughness, the Magnesium Oxide is highly compressed during the process of cable processing, so the cable is kept unchanged in the relative position between the core line and the core line and the sheath when the cable is subjected to bending, flattening, twisting and so on. It will not produce short circuit or affect the electric power. Performance.
Long life: the materials used in cables are all inorganic materials and are not aging.  Its service life can be calculated according to the rate of oxidation corrosion of copper jacket. The data show that the sheath oxidation is 0.25mm, and it takes 257 years at the ambient temperature of 250 C, and the sheath thickness of the mineral insulated cable is generally between 0.34-1.05 and the temperature is below 250 C, so the cable has the characteristics of long life.
Non halogen-free non-toxic: because all cables are made of inorganic materials (metal copper and magnesia powder), even at the high temperature of 1000 degrees C, no smoke, halogen and toxic gas are produced in the real sense of non halogen-free and non-toxic cables.
Five. Resistance to overload and copper sheath can be used as grounding wire
Resistance to overload: as the melting point of copper is 1083, the melting point of Magnesium Oxide is 2800 degrees C, the capacity of the mineral insulated cable can be increased by a section grade compared with the ordinary plastic cable. At the same time, it can withstand a considerable overload, and its overload capacity can reach more than 10 times that of the normal load.
Copper sheath can be used as grounding wire: for mineral insulated cables, because of the continuity of copper sheath and extremely low grounding resistance, it can be used as grounding wire, and no independent grounding wire is required.
