Retardant cables are halogen flame retardant wire and cable fire-resistant cables in one product line. Retardant cable Product Features: flame retardant cable and cable, is under the specified test conditions, the sample is burned, after dropping the test fire, flame spread only within a limited range, residual or residual flame burning in a limited time internal energy self-extinguishing cable. Fundamental characteristics are: In case of fire may be burned out and not run, but you can prevent the spread of fire. More simply, the wire in case of fire, able to burn restrictions in the local scope, no spread, to keep a variety of other devices, to avoid greater losses. Retardant meaning: under specified test conditions, the sample is burned in the fire source is removed, the flame spread on the specimen and only within a limited range of self-extinguishing characteristics that have occurred or to prevent or delay the spread of flame capacity. Burning Wire & Cable Cable is due to external heating to produce a combustible gas, flame retardant to achieve the purpose, must be suppressed combustion caused three elements, namely: combustible gas, heat and oxygen. Thus, the method generally used flame retardant wire and cable jacket material is added in a halide and a halogen-containing metal oxide, from the perspective of flame retardant evaluation, this is an excellent method, however, since these materials contain halogenated thing, when burned release large amounts of smoke and hydrogen halide, so fire when visibility is low, safe evacuation and fire personnel to a great deal of prejudice, but people are more toxic gas suffocation. In addition, after the hydrogen halide gas and water in the air, once the reaction, which generated "hydrogen halide acid", serious corrosion of equipment and buildings resulting in "secondary disaster." Now, with increasing levels of technology, flame retardant halogen issues from the past, and further development of low-halogen, halogen-free flame-retardant. In the development of the production of "communication power with flame resistant flexible cables" on the cable insulation, jacket with a halogen, high decomposition temperature, good mechanical properties halogen-free polymer materials, since the cable free of halides and metal oxides in the combustion does not produce harmful gases and a lot of smoke, there is no possibility that will cause a "second disaster", and also has good mechanical properties and electrical properties, to meet the requirements of the cable, completely changed past inadequacies retardant cable. Retardant cable uses: There may be burned in a fire situation and can not run, but you can prevent the spread of fire. More simply, the wire in case of fire, able to burn restrictions in the local scope, no spread, to keep a variety of other devices, to avoid greater losses. Retardant cable structure Photo: flame retardant cable cable (Shenzhen Xin cable) cable aging retardant cable wires Xin Chun contrast 99.99% of the content of oxygen-free copper, resistance is smaller and better conductivity. Low-grade copper-containing impurities, poor conductivity, electrical properties after several years of use continues to decline. Shenzhen Xin contrast skin jacket made of high quality power cord native poly vinyl record cable material, has good insulation, fire-retardant and anti-aging properties, safety and reliability, long service life. Poor power supply cable jacket insulation using recycled materials, poor flexibility, low hardness, like broken easily by hand, life is short, easy to aging off, causing a major security risk. Combustion contrast (Shenzhen Xin cable) production process: the production process of any cable UL flammability standard UL listed and tested to verify if they meet certain fire rating, can identify words printed on the cable UL fire rating and approval number. :( Air plenum -CMP level burn test / sodium Tolstoy duct experiments Plenum Flame Test / Steiner TunnelTest) which is required in the highest fire safety standards UL Cable (Plenum Cable), applicable safety standards UL910, experiments provisions horizontal air duct means laying multiple samples 87.9KW combustion gas burner (300,000BTU / Hr) 20 minutes. To qualify for the flame can not extend beyond the gas burner flame front from five feet. The maximum peak optical density of 0.5, the mean value of the maximum density of 0.15. This CMP cable is usually installed in the air return duct pressurization system ventilation or air handling equipment in use, was recognized by Canada and the United States has adopted. Comply with UL910 standard FEP / PLENUM materials, good flame retardant properties comply with IEC60332-1 and IEC60332-3 performance than standard halogen material, burning smoke concentration is low. Riser -CMR level :( upright combustion test Riser Flame Test) This is UL standard commercial-grade cable (Riser Cable), applicable safety standards UL1666. In the simulation experiments a predetermined vertical axis laying multiple samples, using a predetermined 154.5KW gas burner (527,500BTU / Hr) 30 minutes. To qualify for the flame can not spread to the upper 12 feet high room. Riser cable does not smoke density specifications, generally used for vertical and horizontal cabling floor use. -CM Commercial grade level :( vertical flame test Vertial Tray Flame Test) This is the UL standard commercial-grade cable (General Purpose Cable), applicable safety standards UL1581. Laying a plurality of predetermined test specimen in the vertical bracket 8 feet high, with a predetermined 20KW ribbon burner combustion (70,000BTU / Hr) 20 minutes. To qualify for the flame can not spread to the upper end of the cable and self-extinguish. UL1581 and IEC60332-3C similar, but a different number of cables laid. Commercial-grade cable is not smoke density standards, generally used only on the same floor level of alignment, should not be used on vertical wiring floors. General Purpose -CMG level :( vertical flame test Vertial Tray Flame Test) This is a general level UL standard cable (General Purpose Cable), applicable safety standards UL1581. Similar commercial and general level of test conditions, the same as approved for use in Canada and the United States. General Cable does not smoke concentration level specification, generally used only trace levels of the same floor, should not be used on vertical wiring floors. Household level - CMX level :( vertical flame test Vertial Wire Flame Test) This is the UL standard household-level cable (Restricted Cable), applicable safety standards UL1581, VW-1. Experimental predetermined specimen held vertically, with the burner combustion test (30,000 TU / Hr) 15 seconds and then stops for 15 seconds, repeated 5 times. Eligibility criteria for not more than 60 seconds over a flame, burning more than 25% of the sample is not available, the pad at the bottom of surgical cotton falling object can not be ignited. UL1581-VW-1 similar to IEC60332-1, just different burning time. This rating does not smoke or toxic specification, only for laying a single cable system in your home or small office. These cables should be laid in bundles, you must casing. Smoke density, halogen content and toxicity levels.
