摘要
在阐明全介质自承式（ ADSS ）光缆护套故障机理的基础上，分析了安装在高压输电线现场的 ADSS 光缆护套故障的原因，讨论了护套抗弧能力的试验方法和在设计中必须考虑的环境条件，介绍了用半导体棒控制干带飞弧来保护护套的方法。
Based on the clarification of the mechanisms of sheath failures on ADSS cables the cause of sheath failures on field－installed ADSS cables is analyzed． Test methods for the arc－resistant capability of cable sheath and the environmental conditions that have to be considered in cable planning are discussed． The method on suppressing arcs with semi－conductive rods for protecting cable sheath is introduced．
