热收缩低压和中压模压型材第3部分:单项材料规范活页103:中压应用的热收缩聚烯烃导电模压型材

[中文适用范围]： 本文件适用于低压和Medium电压（中压）热缩成型件，特别是导电的、适用于环境密封、机械保护、电力电缆终端、接头和终端的应变释放的多种配置。这些成型件适用于-40 °C至100 °C的温度范围。成型件可供应预涂粘合剂。附件A提供了粘合剂兼容性和温度性能的指南。供应商可提供选项。符合本规格的材料达到了既定的性能水平。但是，用户为特定应用选择材料应基于该应用中充分性能所需的实际要求，而不仅仅基于本规格。指定的测试旨在控制成型件的质量，但已知它们设计用于低压和中压电缆附件，因此电气性能将作为组件的一部分进行证明。示例见EN 50393、HD 629和IEC 60502（所有部分）。 [外文原描述]： IEC 62677-3-103:2019 is applicable to heat shrinkable low and medium voltage moulded shapes, conductive, in a range of configurations suitable for environmental sealing, mechanical protection, strain relief for power cable terminations, joints and stop ends. These moulded shapes have been found suitable for use for temperatures between -40 ºC and 100 ºC. The moulded shapes can be supplied with a pre-coated adhesive. A guide to adhesive compatibility and temperature performance is given in Annex A. The manufacturers/suppliers can be consulted for options. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application will need to be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone. The tests specified are designed to control the quality of the moulded shapes but it is recognized that they are designed to be used in low and medium voltage cable accessories and as such electrical performance will be proven as part of the assembly. Examples of this are described in EN 50393, HD 629 and IEC 60502 (all parts). Keywords: heat shrinkable, polyolefin, conductive moulded shapes for medium voltage applications
