The development prospect of the mineral fireproof cable industry is very good, because it brings many benefits to the enterprise when it is used, so it is favored by customers. In order to make everyone more familiar, let's talk about mineral fireproofing. The knowledge points about cables, I hope to bring help to more people.

Nowadays, there are still many people who do not know the basic content of mineral fireproof cables, so as a manufacturer, we will briefly explain that they have the advantages of waterproof, explosion-proof and corrosion resistance. It is for these reasons that it is favored by everyone, because the mineral fireproof cable is sheathed with low-smoke, halogen-free and high-flame-retardant materials, which has high corrosion resistance (the plastic outer sheath is only required in the case of individual chemical corrosion. ), so a dense compaction between conductor, insulation and sheath will be found. Therefore, what everyone needs to understand when using it is that it can not only prevent the damage of water, moisture, oil and some chemical substances. Therefore, there are also some connections that are suitable for places where there is a danger of explosion and various explosion-proof equipment and equipment.

Mineral fire-resistant cables also have the advantage of overload protection. For example, when the line is overloaded, the plastic cable will cause insulation heating or breakdown due to overcurrent or overvoltage. At this time, the mineral insulated cable can be used, so as long as the heat does not reach the melting point of copper, the cable will not be damaged at this time. Even in the case of instant breakdown. Magnesium oxide does not form carbides at high temperatures at the breakdown point. After the overload is cleared, the performance of the cable will not change, and it can continue to be used normally. In addition, the mineral fireproof cable also has the characteristics of high working temperature. For example, this is mainly because the melting point temperature of magnesium oxide of the insulating layer is much higher than the melting point temperature of copper. Therefore, its normal working temperature can reach 250 °C. In the short term, it can continue to operate at 1083°C, which is close to the melting point of copper.
