本指南的范围包括额定电压为5至46 kV的有护套和无护套挤压绝缘电缆中铜屏蔽的腐蚀。讨论了金属屏蔽的功能以及屏蔽线、屏蔽带或屏蔽带严重损失的后果。本文介绍了电缆金属屏蔽层腐蚀的原因，以及评估这种腐蚀的方法。提出了缓解和控制电缆金属屏蔽层腐蚀的建议。

The scope of this guide includes corrosion of copper shields in jacketed and unjacketed extruded dielectric cables rated 5 kV to 46 kV. The function of the metallic shield and consequences of significant loss of shield wires, straps, or tapes are discussed. The causes of corrosion in cable metallic shields, and the methods available to assess this corrosion are described. Recommendations are made for the mitigation and control of corrosion of cable metallic shields.
