标准范围

IEC 63026:2019规定了用于固定海底装置的电力电缆系统、挤压绝缘电缆及其附件的测试方法和要求，额定电压为6 kV（Um=7,2 kV）至60 kV（Um=72,5 kV）。本文件包括材料和部件的电气试验和物理试验，以及适用于海底电缆系统的特定机械试验。这些要求适用于通常安装和操作条件下的铠装单芯电缆和三芯电缆及其附件、终端和接头，但不适用于特殊电缆及其附件，例如用于动态应用（即直接连接到浮动结构）的海底电缆，对于这些电缆，可能需要修改标准测试或设计特殊测试条件。本文件适用于安装在水深达250 m的永久淹没条件下的海底电缆。本文件不包括仅具有机械功能的附件，如悬挂装置或装甲夹。

IEC 63026:2019 specifies test methods and requirements for power cable systems, cables with extruded insulation and their accessories for fixed submarine installations, for rated voltages from 6 kV (U_m = 7,2 kV) up to 60 kV (U_m = 72,5 kV).
This document includes the electrical tests and the physical tests on materials and components as well as the specific mechanical tests that are applicable to submarine cable systems.
The requirements apply to armoured single-core cables and three-core cables in combination with their accessories, terminations and joints for usual conditions of installation and operation, but not to special cables and their accessories, such as submarine cables for dynamic applications (i.e. for direct connection to a floating structure), for which modifications to the standard tests can be necessary or special test conditions be devised.
This document is applicable to submarine cables installed in permanently submerged conditions with water depths up to 250 m.
This document does not include accessories having a mechanical function only, such as hang-offs or armour clamps.
