What is The Difference Between (Flexible) Mineral Insulated Cables and Ordinary

2023-05-23 118

Because the mineral fireproof cable is composed of inorganic substances (copper and magnesium oxide powder), it will not cause fire, nor will it burn or support combustion. Since the melting point of copper is 1083°C and the melting point of magnesium oxide is 2800°C, this cable can continue to supply power in the event of a fire near the melting point of copper. is a real fireproof cable.


The 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, large current carrying capacity, etc. At the same time, it also overcomes many shortcomings of rigid mineral insulated fireproof cables and greatly improves its performance.


Improve insulation stability: The flexible mineral fire-resistant cable not only retains the fire resistance of rigid mineral insulated cables, but also has the characteristics of being unsuitable for moisture absorption, so the insulation performance is more stable.


Improve the withstand voltage level: the withstand voltage level of the flexible mineral fireproof cable can reach 1000V, which reduces many impulse voltages caused by frequent starting of inductance and variable frequency electrical appliances, and accordingly greatly prolongs the service life of the line system.


Full series: 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 meet the requirements of various specifications of building wires and cables. Power cables and control cables.


No intermediate joints: The flexible mineral refractory cable adopts mature twisted cabling 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 constructions such as twisted pairs and wiring to make the cable more flexible. At the same time, since no special terminal connectors are required, installation and laying are more convenient.


Space saving: Flexible mineral fire-resistant cables can provide multi-core cables with large cross-section and long length, avoiding unnecessary laying space caused by the arrangement of multiple cables and intermediate joints.


Public welfare: Due to the improvement of the structure of flexible mineral fireproof cables, a large number of minerals or mineral compounds are used, which not only saves copper resources, but also saves a lot of energy consumption, which has public welfare value and is also meaningful.


Due to the fireproof cable, the copper core is mainly used as the conductor. Therefore, the price of flexible fire-resistant cables mainly depends on the price of copper futures transactions. The price of this mineral fire-resistant cable (micc cable) is greatly influenced by the cost of copper procurement. Therefore, pay attention to the futures trading price of copper before buying fireproof cables.
