标准摘要
[中文适用范围]: IEC 60840:2020+AMD1:2023 CSV 规定了电力电缆系统、单独的电缆和单独的附件、固定安装以及额定电压高于 30 kV (Um = 36 kV) 至 150 kV (Um = 170 kV)。这些要求适用于通常安装和操作条件下的单芯电缆和单独屏蔽的三芯电缆及其附件,但不适用于特殊电缆,例如海底电缆及其附件,需要对标准测试或标准进行修改。可能需要设置特殊的测试条件。本文件不包括挤压绝缘电缆和纸绝缘电缆之间的过渡接头。该第五版取消并取代了 2011 年发布的第四版。该版本构成了技术修订版。与前一版本相比,该版本包括以下重大技术变化: - 除了常规测试外,额定电压高于 52 kV 的气浸式电缆终端还需要根据 IEC 62271-209 进行设计、型式和常规测试。和本文件中规定的型式试验。 - 引入了复合户外终端绝缘子的要求。 - 弯曲测试(型式和资格预审测试)指定的测试圆柱直径已根据 IEC TR 61901:2016 进行了修改。 - 推出了一种低烟无卤护套材料,指定为 ST12。 - 引入了火灾条件下的附加测试:垂直火焰蔓延、烟雾密度、酸度和电导率,应根据电缆声明的防火性能进行应用。 - 增加了导体中水渗透的测试。 ——除了接头的外部保护试验外,还引入了对所有附件的分段绝缘屏蔽的型式试验。 2021年2月勘误的内容已纳入本副本。 [外文原描述]: IEC 60840:2020+AMD1:2023 CSV specifies test methods and requirements for power cable systems, cables alone and accessories alone, for fixed installations and for rated voltages above 30 kV (Um = 36 kV) up to and including 150 kV (Um = 170 kV). The requirements apply to single-core cables and to individually screened three-core cables and to their accessories for usual conditions of installation and operation, but not to special cables, such as submarine cables and their accessories, for which modifications to the standard tests or the setup of special test conditions can be necessary. This document does not cover transition joints between cables with extruded insulation and paper insulated cables. This fifth edition cancels and replaces the fourth edition, published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - Gas immersed cable terminations for use at rated voltages above 52 kV are required to be designed, type and routine tested in accordance with IEC 62271-209 in addition to the routine and type tests specified in this document. - Requirements are introduced for composite outdoor termination insulators. - The test cylinder diameters specified for the bending test (type and prequalification tests) have been modified in line with IEC TR 61901:2016. - A low smoke halogen free oversheath material, designated ST12 is introduced. - Additional tests under fire conditions are introduced: vertical flame spread, smoke density, acidity and conductivity, which shall be applied according to the fire performance declared for the cable. - A test for water penetration in the conductor is added. - In addition to tests on the outer protection of joints, type tests on the screen sectionalizing insulation of all accessories have been introduced. The contents of the corrigendum 1 (2021-02) of the publication and the corrigendum 1 (2025-06) of Amendment 1 have been included in this copy.
