gui chao cable news: extra high fire-非凡电子娱乐

in the past ten years, from the situation of urban buildings and engineering facilities,

no matter how the cause of the fire, the ultimate harm to society and the public is quite tragic.

especially in the developed countries, the city buildings and engineering facilities are almost always used fire-resistant cable,

and almost all of the implementation of bs6387-2013 standards, but still can not get rid of the serious loss of fire.

analysis of the reasons for the discovery that the fire resistance rating of fire-resistant cable is too low.

as a result, the fire department of the country called for emergency response, should be raised as soon as possible fire-resistant cable fire-resistant temperature rating.

up to now, the fire-resistant cable standard of the world, almost all of the fire-resistant cable of the highest temperature rating of 950,

combustion time 3 hours. even if it is considered the most stringent british standard bs6387-2013 standards, the need to burn,

sprinkler and vibration test (cwz) of the fire-resistant cable, the maximum temperature is 950 degrees c. china's standards,

the highest grade refractory temperature is 950-1000 deg c for 90 minutes.

the scene of the fire and the practical experimental data proved that the modern architecture and engineering of fire, is no longer the firewood burning fire,

a large number of organic chemical materials are used in the building, and the petrochemical products are often used in the fire site.

in this case, the temperature of the flame usually exceeds 1000. actual measurements indicate that even in the office of commercial buildings,

when the fire occurs, the upper part of the room flame temperature of 1000-1200 degrees c.

therefore, in today's highly developed society, if not improve the fire resistance of refractory cable,

and continue to use ordinary fire-resistant cable, it lost the significance of building fire prevention cable.

a fire department experts believe that, according to the actual situation of the fire so far, in order to adapt to the modern fire rescue,

it is necessary to improve the fire resistance rating of cables and prolong the burning time in order to minimize the loss of fire.

as for the fire resistance of refractory cable to the number of degrees, the experts believe that should be raised to 1500 degrees, 3 hours,

in order to adapt to the modern fire temperature and rescue difficulty, and of course, the best use of low smoke halogen free materials.

for improving the temperature rating of fire resistant cables, some cable design and manufacturing experts believe that "no need".

this point of view, people feel very surprised. cable product technology innovation, we must follow the market, can not turn a blind eye to market demand.

it is true that there are a lot of technical work to be done to raise the temperature rating of fire resistant cables to 1500 degrees.

process and inspection standards should be improved, there is a certain degree of technical difficulty. however, cable engineering technical personnel should overcome difficulties,

dare to innovate, out of a road of independent technological innovation.
