BTLY isolated (flexible) mineral insulated cable fireproof cable

Purpose
This type of flexible fire-proof cable can ensure emergency use after installation. It can also be used as a temperature-resistant ℃ halogen-free flame-retardant cable and fire-resistant cable. Because this series of cables has a wide coverage, it not only overcomes the shortcomings of rigid fire-proof cables, It has also given full play to the advantages of flexible fireproof cables and provided practical products for key projects, enabling modern projects to achieve the effect of short-circuiting without burning and burning without short-circuiting in electrical lines. The application cases used in this article prove that flexible mineral insulated cables are not only used in It can be successfully applied in fire protection performance such as fire alarms and emergency life-saving circuits, and can also be promoted and applied in cases of high-density current and other special performance requirements.
Features
① The fire resistance standard can pass three assessments: no breakdown under ℃ flame, direct immersion in water spray after ℃, and can withstand knocking vibration under ℃ flame without damage, so that it can Fire resistance performance fully meets the assessment standards. ② This product can produce cores in square specifications, single cores in square specifications, and single cores in square dimensions. The length can be customized according to user needs, and the entire length can be delivered in a complete package without joints. ③ There is no need to wear additional pipes when laying, and it has the same waterproof and anti-impact functions. ④ It has good anti-rat, anti-ant and anti-radiation functions, which can ensure the stability, long life and durability of the cable. ⑤ Low operating temperature, small line loss, strong overload resistance, long service life and high safety. It is especially suitable for applications in projects with environmental protection requirements. ⑥ The highly compacted insulating materials in explosion-proof cables and the cable terminals installed with special sealing sleeves can prevent steam gas and flame from entering the electrical equipment connected to the cable, so they are suitable for wiring in places with explosion risks and various explosion-proof equipment. ⑦The metal sheath of the corrosion-resistant series of mineral insulated cables has high corrosion resistance. For most installations, it does not require additional protective measures, even in places where the metal sheath of the cable is susceptible to chemical corrosion or severe industrial pollution. , because the outermost layer of the cable is protected by a plastic outer sheath, it is still safe. ⑧ High mechanical strength series mineral insulated cables are strong and durable, and can still work normally when the cable diameter is deformed by one-third. Even if they undergo severe mechanical damage, their electrical properties will not be damaged.
Main functions
Using aluminum as the main material for metal tube extrusion instead of copper tube drawing not only simplifies the process and improves efficiency, but also significantly reduces product cost. Aluminum material is only // of the comprehensive cost of copper material. The reason why aluminum pipes can replace copper pipes and do not melt under high-temperature flames is due to the fact that the expanded refractory layer extruded on the outside of the aluminum pipes foams and solidifies under the attack of flames, forming a thick barrier that blocks the flames from affecting the aluminum pipes. of direct injection. Not only the integrity of the aluminum tube is preserved, but also the heating temperature of the mica tape is reduced to below ℃. The stability of the mica tape insulation is undoubtedly improved. The insulation resistance of the mica tape increases with the decrease of temperature
