标准摘要
[中文适用范围]： 本部分IEC 60684规定了两种类型的热收缩聚烯烃套管的要求：无应力控制、无阻燃，标称收缩比最高为3:1。该类套管适用于最高100 °C的温度环境。 - A型：中等壁厚，内径通常可达65.0 mm； - B型：厚壁，内径通常可达95.0 mm。 该套管通常以黑色供货。鉴于此类套管涵盖的尺寸和壁厚范围显著广泛，本标准的附录A提供了可用尺寸范围的指导。实际尺寸应由用户与供应商协商确定。 符合本规范的材料已达到既定的性能水平。然而，用户针对特定应用选择材料时，应基于该应用所需的具体性能要求，而不能仅依据本规范。 该套管专用于中压（MV）电缆附件，其电气性能将作为整体装配的一部分予以验证。相关示例见HD 629及IEC 60502（全部部分）。 [外文原描述]： IEC 60684-3-282:2025 gives the requirements for two types of heat-shrinkable, polyolefin sleeving, stress control, not flame retarded, with a nominal shrink ratio up to 3:1. This sleeving has been found suitable for use up to temperatures of 100 °C. Type A: Medium wall Internal diameter up to 65,0 mm typically Type B: Thick wall Internal diameter up to 95,0 mm typically Since these types of sleevings cover a significantly large range of sizes and wall thicknesses, Annex A provides guidance to the range of sizes available. The actual size will be agreed between the user and the supplier.
