IEC 62677-3-103:2019适用于导电的可热收缩低压和中压模制形状，其配置范围适用于环境密封、机械保护、电力电缆终端、接头和止动端的应变消除。已经发现这些模制形状适用于-40℃至100℃之间的温度。模制的形状可以提供有预涂覆的粘合剂。附录A中给出了粘合剂兼容性和温度性能指南。可向制造商/供应商咨询选项。符合本规范的材料符合既定的性能水平。然而，用户对特定应用的材料的选择将需要基于该应用中足够性能所必需的实际要求，而不是仅基于本说明书。规定的测试旨在控制模制形状的质量，但应认识到，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得到验证。在EN 50393、HD 629和IEC 60502(所有部分)中描述了这方面的示例。 关键词:热收缩，聚烯烃，用于中压应用的导电模制形状

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).
