绝缘软套管. 第3部分: 各种型号软管的规格. 活页284: 石油屏障应用的热缩套管

[中文适用范围]： 本部分IEC 60684规定了用于油屏障、中压电缆连接和终端应用的热缩套管的要求，其标称收缩率高达3:1。这些套管已发现在高达80°C的温度下使用合适。 类型A：基于聚烯烃。 类型B：基于氟聚合物，具有增强的耐油性。 这些套管通常以半透明形式提供。 由于这些类型的套管覆盖了尺寸和壁厚的显著大范围，本文件中的附录A表A.1和A.2提供了可用尺寸范围的指南。实际尺寸将由购买者和供应商商定。 符合本标准的材料满足既定的性能水平。然而，用户为特定应用选择材料应基于该应用中足够性能所需的实际要求，而不是仅基于本标准。 该套管设计用于中压电缆附件，因此电气性能定义为组件的一部分。例如在HD 629和IEC 60502系列中描述。 [外文原描述]： IEC 60684-3-284:2014 gives the requirements for heat-shrinkable sleevings for oil barrier, medium voltage cable jointing and termination applications, with nominal shrink ratios of up to 3:1. These sleevings have been found suitable for use up to temperatures of 80 °C. Included are Type A: polyolefin based and Type B: fluoropolymer based, enhanced oil resistance. These sleevings are normally supplied as translucent. Since these types of sleevings cover a significantly large range of sizes and wall thicknesses, Annex A, Tables A.1 and A.2, in this document, provide a guide to the range of sizes available. The actual size will be agreed between the purchaser and supplier. Materials which conform to this standard meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this standard alone. This sleeving is designed to be used in MV cable accessories and as such, electrical performance as defined as part of the assembly. Examples of this are described in HD 629 and IEC 60502 series.
