IEC 60684-3-285:2014给出了中压接头绝缘用热缩套管的要求，具有一系列热缩比。该套管适用于100°C以下的温度。这些套管通常为红色或棕色。由于此类套管的尺寸和壁厚范围很大，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，因此电气性能将作为组件的一部分进行验证。 HD 629和IEC 60502中描述了这方面的示例。 关键词:中压接头绝缘热收缩套管、电气用软绝缘套管

IEC 60684-3-285:2014 gives the requirements for heat-shrinkable sleeving for medium voltage joint insulation, with a range of shrink ratios. This sleeving has been found suitable up to temperatures of 100 °C. These sleevings are normally supplied in colour, red or brown. Since this type of sleevings covers a significantly large range of sizes and wall thicknesses, 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 medium voltage cable accessories and as such electrical performance will be proven as part of the assembly. Examples of this are described in HD 629 and IEC 60502. Keywords: heat-shrinkable sleeving for medium voltage joint insulation, flexible insulating sleeving for electrical purposes
