Halogen-Free Low Smoke and Fire Ratardant Power Cable
Product Name: Halogen-Free Low Smoke and Fire Ratardant Power CablePlace of Origin: ChinaProperties and functions:The products of halogen-free low smoke flame-resistant (fire- retardant) power cableare provided with excellent properties of mechanical physical performance, electricaland flame-resistant (fire-retardant) performances, and have the advantagesof halogen free, low smoke, etc. The products are suitable for fixed installedtransmission and distribution power lines, which require specially for firesafety, such as tall buildings, metros, oil platforms, computer centers, nuclearpower stations, hospitals and ships.Properties of application:1) Max. rated temperature of the conductor is 90oC2) Period of short circuit shall not exceed 5s, and the max. temperature of theconductor shall not exceed 250oC3) The permissible bending diameter of the cable:a) For single-core cable: 20 (D+d)±5%b) For multi-core cable: 15 (D+d)±5%c) D is actual overall diameter of the cable sample (mm), d is actual diameterof the conductor (mm)4) There are six types of halogen-free low smoke fire retardant (flame resistant)power cables:a) WDZ(K)-YJY: halogen-free low smoke flame-resistant XLPE insulated polyolefinesheathed power cableb) WDZ(K)-YJY2: halogen-free low smoke flame-resistant XLPE insulated steel-tapearmored polyolefine sheathed power cablec) WDZ(K)-YJY33: halogen-free low smoke flame-resistant XLPE insulated steel-wirearmored polyolefine sheathed power cabled) WDN(K)-YJY: halogen-free low smoke fire-retardant XLPE insulated polyolefinesheathed power cablee) WDN(K)-YJY23: halogen-free low smoke fire-retardant XLPE insulated steel-tapearmored polyolefine sheathed power cablef) WDN(K)-YJY33: halogen-free low smoke fire-retardant XLPE insulated steel-wirearmored polyolefine sheathed power cableThe different specifications are based on different voltage rates, number of coresand nominal cross-section area (mm2). The nominal cross-section areaof 3.6/1kV varies from 1.5 to 240mm2, and the 3.6/6 - 8.7/10kV is from25 to 240mm2.
