本指南介绍了交流输电系统中使用的额定电压为5 kV至500 kV的屏蔽、层压介质绝缘电力电缆系统的直接电压验收和维护测试的推荐做法和程序。本规范适用于所有类型的层压电力电缆系统，例如用于传输或分配电力的纸绝缘金属护套、高压管型、低压充气电缆和低压和中压自给式充液电缆。列表测试水平假设电缆系统具有有效接地的中性点系统或接地的金属屏蔽。

This guide presents the recommended practices and procedures for direct voltage acceptance and maintenance testing of shielded, laminated dielectric insulated power cable systems rated 5 kV to 500 kV used in ac transmission systems. It applies to all types of laminated power cable systems such as paper-insulated metallic-sheathed, high-pressure pipe-type, low-pressure gas-filled, and low and medium pressure self-contained liquid-filled cables that are intended for the transmission or distribution of electric power. The tabulated test levels assume that the cable systems have an effectively grounded neutral system or a grounded metallic shield.
