cable news: flame retardant cable will accelerate the development of the cable industry-非凡电子娱乐

in recent years, the domestic cable fire caused by frequent fire, the loss of the economy, but also a threat to people's safety. cable industry as the main blood vessels of china's economy, making the demand for flame-retardant cables will increase. but most people lack the correct understanding and understanding of the flame retardant cable.

flame retardant cable

flame retardant cable, as its name implies, is burning, the spread of the fire can be controlled within a certain range, and within a certain period of time to extinguish their own. this characteristic, together with the low cost of the cable, makes the fire retardant cable widely used in the cable laying. perhaps, many people distinguish between flame retardant and fire - retardant cable, in fact, their characteristics are: insulation layer, etc. the properties of flame retardant sheath material of flame retardant cable; and fire-resistant cable is to add a layer of refractory. maybe you will have doubts, flame retardant cable can really prevent the spread of a fire? how to judge the purchase is flame retardant cable today? chinese cable network xiaobian to introduce, in accordance with the provisions of the standard, the fire can be removed after over a period of time is qualified to extinguish the flame retardant cable, flame retardant also need to check the cable, namely product specifications, laying mode and self extinguishing time.

market characteristics

as everyone knows, cable is everywhere in our daily life, so the use of cable will inevitably occur in the fire, so how to emergency fire? first of all, to close the breaker switch, cut off power supply, because the fire appliances or line may have been charged, not power, will increase the fire and electric shock accident; second, if special reasons can not be cut off, to choose the non conducting fire extinguishing agent, such as carbon dioxide, 1211 fire extinguishers and so on; finally, when the fire, should pay attention to the shortest distance, high and low voltage determines the shortest distance from the nozzle to the charged body; if the larger buildings or objects on fire, the most secure method is used to prevent the spread of fire fire temperature sensing automatic water spraying device, can also be installed inside the walls or cable pipe.

the installation of the cable is so important that the following aspects should be paid special attention when selecting and laying the flame-retardant cable:

first of all, low smoke and low halogen flame retardant cable burning, can send out a kind of halogen acid gas, the smell is corrosive, will increase the workload of firefighters, the fire may delay time, bring a lot of unnecessary loss. therefore, in many public places, should be laid halogen free low smoke flame retardant cable, which can increase the safety factor in public places.

second, flame retardant cable has three major categories, a, b, c3 class; appearance can not distinguish between categories, so the choice, to choose a regular cable manufacturers.

third, halogen free low smoke flame retardant cable, low corrosion, low smoke, in the laying, the corresponding to have greater bending radius.

at present, the cable fire occurs in power cable production sites, because these places use around every corner, in some corner of the environment is relatively poor, the tunnel or overhead laying, layout density is relatively high, coupled with the cable in the heating state during operation. these factors accelerate the market demand for flame retardant cables.

it is generally believed that the loss caused by fire in buildings, such as the use of inferior wires and cables, has become a common understanding in today's society. therefore, regardless of the size of wire and cable enterprises pay attention to the real reason for the occurrence of cable fire, attention to the quality of cable products, but also to carry out effective fire control, to ensure safe production environment.
