IEC 60684-3-284:2014给出了油屏障、中压电缆连接和终端应用的热缩套管的要求，标称热缩比高达3:1。这些套管适用于80°C以下的温度。包括A型:聚烯烃基和B型:氟聚合物基，增强耐油性。这些套管通常是半透明的。由于这些类型的套管涵盖的尺寸和壁厚范围很大，因此本文件附录a表a.1和a.2提供了可用尺寸范围的指南。实际尺寸将由买方和供应商商定。符合本标准的材料符合既定的性能水平。然而，用户为特定应用选择材料时，应基于该应用中充分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。HD 629和IEC 60502系列中描述了这方面的示例。 关键词:热缩套管、隔油层、中压电缆连接、终端应用

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.
