标准摘要
[中文适用范围]： 本国际标准规定了额定电压不超过 320 kV 的固定陆地装置@采用挤压绝缘电缆及其附件的高压直流输电电缆系统的测试方法和要求。本标准范围内的《挤压绝缘》是指通过热塑性材料（例如聚乙烯）或交联材料（例如交联聚乙烯@乙烯丙烯橡胶@等）挤出制造的绝缘材料。绝缘材料可以是未填充的或填充的（例如，用矿物或碳）。这些要求适用于单芯电缆及其附件@户外和气体绝缘系统终端@接头@和通常安装和操作条件下的非对称接头@，但不适用于特殊电缆及其附件@，例如海底电缆@可能需要对标准测试进行哪些修改，或者可能需要设计特殊的测试条件。 [外文原描述]： IEC 62895:2017 specifies test methods and requirements for transmission power cable systems, cables with extruded insulation and their accessories for fixed land installations, for rated voltages up to and including 320 kV. Within the scope of this standard “extruded insulation” means insulation manufactured by extrusion of either thermoplastic (e.g. polyethylene) or crosslinked (e.g. crosslinked polyethylene, ethylene propylene rubber, etc.) material. The insulation material may be either unfilled or filled (e.g. with mineral or carbon). The requirements apply to single-core cables in combination with their accessories, outdoor and terminations for gas insulated systems, joints, and asymmetric joints for usual conditions of installation and operation, but not to special cables and their accessories, such as submarine cables, for which modifications to the standard tests may be necessary or special test conditions may need to be devised.
