Because the mineral fireproof cable is composed of inorganic substances (copper and magnesium oxide powder), it will not cause a fire, nor can it burn or support combustion. Because the melting point of copper is 1083°C and the melting point of magnesium oxide is 2800°C, this kind of cable can continue to supply power when a fire occurs near the melting point of copper. It is a real fireproof cable.
Ratio of flexible mineral insulated fireproof cable to rigid (hard) mineral insulated fireproof cable:
Flexible mineral fireproof cable not only has the advantages of hard cable fireproof, explosion-proof, temperature resistance, and large current carrying capacity. But also overcomes many shortcomings of rigid mineral insulated fireproof cable, and its performance is greatly improved.
Improved Insulation Stability: Flexible mineral fire-resistant cables not only retain the fire-resistant properties of rigid mineral insulated cables, but also have the characteristics of being unsuitable for moisture absorption, so the insulation performance is more stable.
Improved Voltage Resistance Level: The withstand voltage level of the flexible mineral fireproof cable can reach 1000V, which reduces many impulse voltages caused by the frequent start of inductance and frequency conversion appliances, and correspondingly greatly extends the service life of the line system.
Full Range: Flexible mineral fireproof cables can be processed into single-core or multi-core structures according to the actual needs of users, with a maximum of 96 cores, which can almost cover the requirements of various specifications of construction wires and cables such as power cables and control cables.
No Intermediate Joint: The flexible mineral fire-resistant cable adopts mature twisting and cable-forming technology, and can be produced according to user requirements, which not only reduces the cost of joints, but also improves and realizes the consistency of the whole line.
Flexible And Easy To Install: Flexible Mineral fire-resistant cables use traditional cable structures such as twisted wires and wiring, making the cables more flexible. At the same time, because no special terminal connector is required, installation and laying are more convenient.
Space Saving: Flexible mineral fire-resistant cables can provide multi-core cables with large cross-sections and long lengths, avoiding unnecessary laying space caused by the arrangement of multiple cables and intermediate joints.
Public Welfare: Due to the improvement of the structure of the flexible mineral fireproof cable, a large number of minerals or mineral compounds are used, which not only saves copper resources, but also saves a large amount of energy consumption, and the public welfare value is also very significant.
Because of fireproof cables, copper cores are mainly used as conductors. Therefore, the price of flexible fireproof cables mainly depends on the price of copper futures transactions. The price of this mineral fireproof cable(micc cable) is greatly affected by the purchase cost of copper. Therefore, pay attention to the futures trading price of copper before buying fireproof cables.
