November 9, 2022 Flexible fireproof cable Advantages of
Flexibility Fireproof cable , also known as "flexible inorganic mineral insulated cable", because it is softer than mineral insulated cable, easy to install and lay, and also has the requirements of relevant fire standards and specifications. At present, it has developed rapidly in the industry and is mainly used in places with high fire protection requirements such as environmental protection and fire protection. New energy cable
1： Tensile center
According to the number of flexible cable cores and the space of the cross area of each core, there should be a real central filling line in the center of the cable as far as possible (instead of the garbage core line made of some fillers or waste as usual). This method can effectively protect the stranded wire structure and prevent the stranded wire from drifting to the central area of the cable.
2： Core strand
The softer the flexible core strand structure is, the better. The conductor is made of ultra-fine oxygen free fine stranded copper wire.
3： Core insulation
The insulating materials in the flexible cable cannot be taped to each other. At the same time, the insulating layer also needs to support each individual conductor. Therefore, only the prepared high-pressure formed PVC/TPE materials can prove their reliability and durability in the application of millions of meters of cables suitable for drag chains.
4： Strand structure
The flexible cable stranded structure must be wound around a stable tensile center with the best twisted pitch. However, due to the use of insulating materials, the stranded wire structure should be designed according to the state characteristics of its movement. When the number of cores is z 12, bunched stranding should be adopted.
5： The inner sheath of flexible cable extrusion molding should replace the cheap wool material or other fillers, so as to ensure that the stranded wire structure will not be scattered.
6： Shielded high flexible cable tightly weaves the shield layer outside the inner sheath through the optimized braiding angle. Loose braided tape will reduce the signal anti-interference ability and the shielding layer line will break and become invalid. The tightly woven shielding layer also has anti torsion and anti torsion properties.
7： Outer sheath The outer sheath of flexible cables made of different improved materials has different functions: UV resistance (UV: UV), low temperature resistance, oil resistance and high cost performance. But the sleeves have one thing in common: high wear resistance, and will not adhere to anything. The outer sheath must be highly flexible, but also have a support function, so it must be extruded into.
