IEC 60227-6:2001标准适用于额定电压为450/750V及以下的聚氯乙烯绝缘电缆,主要用于升降机电缆和柔性连接电缆。该标准规定了电缆的结构、材料、试验方法和性能要求。
该标准要求电缆的导体采用铜或铜合金,绝缘层采用聚氯乙烯材料,护套层采用聚氯乙烯或聚氨酯材料。电缆的额定电压为450/750V,最高工作温度为70℃。
在试验方面,该标准要求对电缆进行导体电阻、绝缘电阻、耐电压、机械强度、燃烧性能等多项试验。其中,机械强度试验包括弯曲试验、拉伸试验和扭曲试验等。
此外,该标准还对电缆的外观、尺寸、标志等方面进行了详细的规定。例如,电缆的外观应平整光滑,无明显的破损、划痕和气泡等缺陷;电缆的标志应包括电缆型号、额定电压、制造商名称等信息。
IEC 60227-6:2001标准的实施,可以保证升降机电缆和柔性连接电缆的质量和安全性能,为电气设备的正常运行提供了可靠的保障。
