D - Actual diameter of cable; 2. Be careful when bending, for example, with molding guide, etc.Performance parameter of Cable:Insulation resistance of CableAir impermeability testWith 0.25~0.35MPa dry air or nitrogen filled in the corrugated copper sheath and hold for 2 hours, the pressure value will not go down.Voltage resistance testThe finished cable should be able to pass AC test: 3000V/5min for Control cable, 3500V/5min for power cable.Fire-resistance testFlame temperature for test is 950~1000ºC, and the burning time is 180min. The test requirements are as below: (mm)Cable actual diameterTest requirementD≤20BS6387:2013C,W,Z,Test according to the test method of C, W, Z required by BS6387:2013, and keep the circuit perfectly.D>20BS8491:2008,Test according to BS8491:2008, and keep the circuit perfectly.The Release of acid gasFor RTTYZ finished cable, the PH value of its low-smoke halogen-free sheath should not be less than 4.3, and the conductivity should not be larger than 10μS/mm.Smoke densityFor RTTYZ finished cable, its low-smoke halogen-free sheath can pass the burning test under certain conditions, and the light transmittance is not less than 60%.Advantage: Excellent fire-resistance. Fire resistance rating can not only reach GB12666.6 Grade A (950ºC, 90min), but also reach BS6387-1994 standard requirement; During the burning, the cable can still bear water spray and mechanical impact. Long continuous length. No matter single core or multi cores, the length can satisfy the demand of power supply, and the limiting length can reach 2000 meters.Large section. Section area of single core cable can reach 1000 mm2, and 240mm2 for multi cores.The cable is flexible, and can be in coil packed, and the bending radius is more than 20D.No-smoke and no toxic when burning. The insulation is inorganic material, which will not generate any harmful gas when burning.Large overload capacity. The cable not only have large carrying capacity, but also have large overload capacity. According to wire arrangement requirement, normal surface temperature of cable is not more than 70ºC. If the ware arrangement can not be touched, and no touch with the combustible building materials, the cable sheath temperature can reach 105ºC. The allowed working temperature can reach 250ºC when overloaded.Copper sheath has good anti-corrosion, that no need to wear additional tube.No electromagnetic interference. Under the shielding of the copper sheath, the cable will not disturb the signal and transmit information of control cable.Good safety. The cable can ensure the normal power supply in fire, and the fire-fighting equipment can not only reduce fire damage, but also ensure personal safety. The copper sheath is good conductor, which is best ground lead, and cover cable overall length. Long service life. Inorganic insulation material is high temperature resistance and not easy to aging, so the service life is much longer than organic insulation cable, and almost can reach same life as buildings.Transportation and installation are easy, similar to normal cables.High economy. Due to advanced production process and easily installation, the comprehensive costs is much lower.
