Guangdong cable manufacturer: What are the advantages of fire safety cables
Fire safety cables have become an indispensable part of our daily life and production process. Secondly, wires and cables cause accidents, especially when the wires and cables explode after burning, it is easy to lead to casualties. Every year, all kinds of wires and cables cause safety accidents. Safety accidents continue, general wire and cable enclosures are basically plastic and rubber goods. A lot of smoke and harmful gases are released after various materials are lit. Once the cable burns and explodes, it will have a serious impact on the surrounding residents and the environment.
Guangdong cable manufacturer: Why do some cables catch fire or even explode? Cables can catch fire for many reasons. We summarized a lot of common conditions: short circuit fault, load, penetration, cable head damage, external flame, the general situation is that the cable sheath is damaged, may lead to cable short circuit fault. External wire jacket raw materials will ignite, and if the cable long-term load, there will be more serious heating. If this background running refers to the old cable, it is very easy to disconnect and cause a fire.
Guangdong cable manufacturer: Another very common reason is cable head damage. If the surface of the cable head is wet and cold or stained, the porcelain waterproof sleeve of the cable head will break and the transmission wire is too small, which will also cause flying arc and fire, so that the insulation layer on the surface of the cable head will cause the transmission wire. Naturally, another main reason for the cable sheath to ignite is that the outside open fire igniting the cable, causing the cable to ignite and even explode.
Therefore, in order to reduce the loss caused by cable damage, fire safety cable is formulated. Fire safety cable is a general name for the characteristics of flame retardant cable and fire safety cable. It has a fire retardant rating, but a lot of people can't tell the difference. The concept of cable and fire safety cable, generally speaking, fire safety cable can replace flame retardant cable, but flame retardant cable can not replace fire safety cable. Mainly because they work differently.
The working principle of flame retardant cable is completed by the flame retardant action of halogen bulb, and there is no halogen flame retardant cable. It uses accumulated water to cool down quickly, but the working principle of fire safety cable and flame retardant cable is not the same. The raw material of fire safety cable contains a kind of biotite raw material, which has high flame retardant and can be started normally in case of fire.
Guangdong cable manufacturers: fully understand the two working principle, can know that flame retardant cable is also afraid of fire, but because of the use of fireproof material, it can kill the communication seat fire, and flame retardant cable of different types. It has a fire layer structure. Even in the heat of the day, it is possible to replace flame-retardant cables with fire-proof safety cables in most cases.
So wire and cable manufacturers of flame retardant cables and fire safety cables are not easy to ignite? Flame retardant cable has high flame retardant, small ignition spacing, and will be automatically extinguished after the open flame disappeared, but flame retardant cable itself will still ignite, can not be fully burned. Ignite. The same goes for fire safety cables, and they ignite. Flame retardant cable according to the flame retardant effect of the material to fast cooling, and flame retardant cable with its flame retardant layer to ensure that it can operate normally in the popular, so flame retardant cable is better than fire under some premise of the application of flame retardant cable.
Guangdong cable manufacturer: Thank you for watching, my company has a variety of cables, welcome to consult.
