本指南建议在配电电缆终端杆上安装电涌放电器，以将中压配电电缆上的总外加瞬态电压降至最低。本文件未提及或考虑接地极技术、极接地值和系统接地网值。

This guide suggests surge arrester installation methods at distribution cable terminal poles in order to minimize the total impressed transient voltage on medium-voltage distribution cables. Grounding electrode techniques, pole ground values, and system ground grid values are not addressed or considered in this document.
