1.1 本规范涵盖导线尺寸为14 AWG[2.08 mm的电线和电缆的交联聚乙烯绝缘 2. ]并且更大。这种绝缘材料的基础聚合物基本上由聚乙烯或聚乙烯共聚物组成。 1.2 这种类型的绝缘适用于潮湿和干燥地区的电力电缆，额定电压不超过2000 V，导体温度不超过90 °C用于正常操作。对于铜导体，可以在未涂覆的金属上施加绝缘层。 1.3 本规范所涵盖的材料不具有抗阳光和耐候性，除非它们是炭黑颜料或含有为这种保护而设计的添加剂系统。 1.4 在许多情况下，绝缘不能进行测试，除非它是在导体周围形成的。因此，在本标准中，对绝缘电线进行测试只是为了确定绝缘的相关性能，而不是为了测试导体或完整的电缆。 1.5 无论何时以不同的单位显示两组值，第一组中的值都是标准值，而括号中的值仅供参考。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This specification covers a crosslinked polyethylene insulation for electrical wires and cables in conductor sizes 14 AWG [2.08 mm 2 ] and larger. The base polymer of this insulation consists substantially of polyethylene or a polyethylene copolymer. 1.2 This type of insulation is suitable for continuous use on power cables in wet and dry locations, for voltage ratings not exceeding 2000 V and at conductor temperatures not exceeding 90 °C for normal operation. For copper conductors, the insulation can be applied over the uncoated metal. 1.3 Materials covered by this specification are not sunlight and weather resistant unless they are carbon black pigmented or contain an additive system designed for this protection. 1.4 In many instances the insulation cannot be tested unless it has been formed around a conductor. Therefore, tests are done on insulated wire in this standard solely to determine the relevant property of the insulation and not to test the conductor or completed cable. 1.5 Whenever two sets of values are presented, in different units, the values in the first set are the standard, while those in parentheses are for information only. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
