摘要
电力通信的发展使ADSS光缆得到广泛应用,沿电力线路架设的ADSS光缆存在电腐蚀现象,严重时会造成光缆外护套破裂甚至断缆,为了更好地解决这一问题,应对ADSS光缆电腐蚀的产生和预防进行分析。电腐蚀现象产生的原因各不相同,通过对干带电弧、电晕放电引起的2种电腐蚀形成机理的分析,总结出在ADSS光缆生产、设计、施工、维护管理等环节中,采取的技术手段和预防措施,使ADSS光缆的电腐蚀问题得到了更好的解决。
ADSS cable is wildly used in power telecommunication sector. But the electric corrosion can damage the sheath of the cable, sometime even break the cable. This paper analyzes the reasons of electric corrosion, for example, the corrosion caused by dry strip ARC and corona discharge. It proposes the technical suggestions and prevention measures for the production, design, construetion and maintenance of ADSS cable.
