The utility model has the advantages that:
1, structural design: the horizontal airspace integrated distribution cable of the utility model PSC adopts skeleton level to ventilate in the structure process of cable design, realizing good cable center ventilates, reduce the cable operating temperature in cable running, greatly reduced the possibility that cable fault or fire occur.The horizontal airspace integrated distribution cable of PSC cable material has all adopted the cable material of environment-friendly high fire-retardant, considers that the transfer of data of data cable is not subject to outside electromagnetic interference simultaneously, and data cable adopts and is no less than 85% proof copper-wire braided shielding.Such as: what cable jacket was used is special-purpose low-smoke halogen-free polyolefin material, has high flame retardant and low smoke and zero halogen characteristic; Cable central cross skeleton adopts FEP (fluoroplastics) material, in frame design process, at centre design ventilation hole, has better realized the horizontal performance of ventilating of cable; What insulating barrier adopted is FEP material; What packing material adopted is glass cord or inorganic asbestos cord; Data cable adopts and is no less than 85% proof copper-wire braided shielding, and cable conductor adopts high-quality copper free wire.The cable material adopting is all a kind of high temperature resistant and extremely difficult materials that fire.This is the maximum difference on the cable material of the difference of horizontal airspace integrated distribution cable and other other flame retardant ratings just;
2. the horizontal airspace integrated distribution cable of the test of the horizontal airspace integrated distribution cable of PSC: PSC is strictly tested by the flame retardant test grade of CMP cable, employing be stainer passage (Steiner Tunnels) test method.In the circulation of air environment of 7 cubic metres per second, the flame spread distance of cable and smokescope are tested.Test adopts the method for testing of horizontal firing, utilizes 87.9KW gas burner oven as burning things which may cause a fire disaster, and the testing time continues 20 minutes, and maximum flame spread distance is 1.5 meters, and maximum smoke density is 0.5, and average smoke density is 0.15.As long as meet above-mentioned method of testing and the data value of test request, no matter which kind of material this product is used make, its flame retardant rating can be judged to be qualified products;
3. the security feature of the horizontal airspace integrated distribution cable of PSC: the flame-retarding characteristic of the horizontal airspace integrated distribution cable of PSC, mainly refers to that can delay flame spreads the characteristic that makes the unlikely expansion of fire along cable.That is to say, once breaking out of fire, this cable itself is difficult to burning or can only smoulder after meeting fire, and after blocking-up burning things which may cause a fire disaster, necessarily prolongs in combustion distance the characteristic of flame automatic distinguishing in certain hour.To reach the object that stops the intensity of a fire to expand.The flame-retarding characteristic of cable is the most important part of its fail safe, is the basis of whole cable fail safe, and cable has possessed after good flame-retarding characteristic, could stop the generation of burning, thereby just can guarantee other all security performances;
4. the low cigarette characteristic of the horizontal airspace integrated distribution cable of PSC: when fire occurs, be often to have no big fire, seen dense smoke.Thick smoke, not only makes people can't keep one's eyes open, and cannot see the route of escape, and its a large amount of dust carrying and imperfect combustion particulate matter, cause personnel to suffocate and die simultaneously.Another test emphasis of the horizontal airspace integrated distribution cable of PSC is the smoke density after product burning.In U.S. NEC 262 standards and UL910 test request the flue gas of CMP grade cable is required be: maximum smoke density < 0.5, average smoke density <0.15.Guarantee the light transmittance of scene of fire, guarantee that the personnel in the scene of a fire can escape smoothly.
In order to understand the water clock characteristic with management and control material, in the FIPEC Scenarios of European Union 1 & 2 method of testings, water clock is had to clear and definite classification, in test 1200 seconds, observe the water clock situation of cable." cable classification system for fire performance " standard that China is about to promulgate has also been quoted this testing standard, by water clock performance from excellent to difference, be D0 (in 1200 seconds without water clock), D1 (in 1200 seconds water clock time <10 second), three grades of D2 (in 1200 seconds water clock time >10 second).And the horizontal airspace integrated distribution cable of PSC, its main material is FEP, even and FEP at high temperature produces molten condition, it can water clock yet, does not burn, and does not decompose.So just can avoid flame indirectly to periphery material, to produce spreading of water clock mode.Be conducive to put out as early as possible the intensity of a fire;
5. the horizontal airspace integrated distribution cable of PSC horizontal airspace integrated distribution cable physics and electrical characteristic: PSC not only has above multiple security feature, in actual application, more has good physics and electrical characteristic.Due to the high flame retardant characteristic of the horizontal airspace integrated distribution cable of PSC, in common project wiring, can allow the wiring of the horizontal airspace integrated distribution cable of PSC open type, do not need poling or walk to seal wire casing.Not only can save a large amount of wiring conduits and wire casing, also aspect cable lay construction, greatly improved efficiency of construction.Also convenient to administering and maintaining of cable in the future.
In addition, what the insulating barrier of the horizontal airspace integrated distribution cable of PSC was used is FEP material, and the dielectric constant of FEP material is with respect to the dielectric constant of PE material smaller (dielectric constant of FEP is about 2.1, and the dielectric constant of PE is 2.25-2.35).Insulating barrier dielectric constant values more approaches 1 (dielectric constant of vacuum is 1), and also less on the impact of the transmission of cable signal and insulating performance of cable, the electric property of cable is just better.So under equal conditions, the characteristic of the horizontal airspace integrated distribution cable of PSC is better than other cable.
