绝缘电缆的导线

[中文适用范围]： 涵盖了从低电压到高压系统中常见的各类导线产品，确保不同型号导体在电气性能上的统一性和兼容性。标准内容对导体的结构形式进行了明确分类，包括实心、绞合等常见形态，并设定了相应的直流电阻限值要求，为导体制造、质量检验及工程应用提供了统一的技术依据。通过规范导体的基本参数，该文件有助于提升电缆产品的互换性，保障电力传输过程中的安全性和可靠性。此外，它还涉及了导体材料的质量控制要求，为行业内的生产制造提供了明确的技术指导，促进了全球范围内相关产品的规范化发展。 [外文原描述]： Specifies standardized nominal cross-section areas from 0.5 mm2 to 2 000 mm2, numbers and diameters of wires and resistance values of conductors in electric cables and flexible cords. Classifies conductors for: 1.Cables for fixed installations -Class 1, solid conductors; -Class 2, stranded conductors. 2.Flexible copper conductors -Class 5, -Class 6 (more flexible than Class 5). Includes table of temperature correction factors kt for conductor resistance to correct the measured resistance at t °C to 20°C. Does not apply to conductors for telecommunication purposes. Applies to conductors of special design only when stated in the specification for the type of cable. Conductors of special design are, for example. conductors for pressure cables, conductors in extra-flexible welding cables or in special types of flexible cables for having the cores twisted together with unusually short lays. This publication supersedes IEC 60180 (1965). Note: -In this edition, the number of classes of conductors has been reduced from 6 to 4.
