Fireproof cable has become an indispensable item in our daily life and production, followed by accidents caused by wires and cables, especially when wires and cables explode after combustion, it is easy to cause casualties. Every year, all kinds of wires and cables cause accidents. The fire accident continues. Most of the shells of ordinary wires and cables are plastic and rubber products. These materials will release a lot of smoke and toxic gases after the fire. Once the ABC Cable burns and explodes, it will also cause serious damage to the surrounding residents and environment.
Why do some cables catch fire or even explode? There are many reasons for AAAC Cable fires. Xiaobian summarized five common situations: short circuit, overload, breakdown, burning of cable head and external fire source. Generally, the insulation layer of the cable is damaged, resulting in cable short circuit. The outer sheath material will burn and severe heating will occur if the cable is overloaded for a long time. If the old cable is running at this time, it is easy to break the line and cause a fire.
Another very common reason is that the cable head is burned. If the surface of the cable head is wet or dirty, the ceramic sleeve of the cable head will break and the conductor is too small, which will cause arcing and fire, thus insulating the surface of the cable head and causing the conductor. Of course, another reason for the burning of the insulation layer is that the external fire source burns the cable, causing the cable to burn or even explode.
Therefore, in order to reduce the loss caused by cable burning, a fireproof cable is designed. Fireproof cable is a general term for the characteristics of flame retardant cable and fireproof cable. They all have certain flame retardancy, but many people can’t distinguish flame retardancy. The concept of cable and fireproof cable. In terms of its characteristics, fireproof cable can replace flame-retardant cable, but flame-retardant cable cannot replace fire-retardant cable. This is because they work differently.
The working principle of flame retardant cable is realized through the flame retardant effect of halogen, as well as halogen-free flame retardant cable. It uses precipitated water to reduce the temperature, but the working principle of fireproof cable is different from that of flame retardant cable. The material of fireproof cable contains a kind of mica material, which has high fire resistance and can be used normally in fire.
After understanding the working principles of the two, it can be seen that the flame-retardant cable is also afraid of fire, but due to the use of flame-retardant materials, it can stifle the fire in the communication base, and the flame-retardant cable is different. It has a fireproof layer structure. Normal operation can be maintained even in a fire, so in many cases, fireproof cables can be used instead of flame retardant cables.
Will flame retardant cables and fireproof cables not burn? Flame retardant ACAR Cables are highly nonflammable, with small combustion distance, and can be extinguished automatically after the fire source disappears, but the flame retardant cables themselves will still burn and cannot burn completely. Burning. Similarly, fireproof cables are the same and will burn. Flame retardant cables reduce the temperature through the flame retardant effect of special materials, and flame retardant cables rely on their unique flame retardant layer to ensure that they can work normally in fire. Therefore, flame retardant cables are better than flame. In some cases, flame retardant cables are used.
