全介质自承式(ADSS)光缆具有绝缘良好、抗拉强度高、可与电力线同杆塔架设等优点,但是存在着易电腐蚀的缺陷。介绍了ADSS光缆耐电腐蚀试验的原理,并根据IEEE P1222光缆检测标准设计ADSS光缆耐电腐蚀试验。经过1 000 h的盐雾试验,通过分析断缆事故现场的ADSS光缆表面的腐蚀程度、表面的泄漏电流,寻找断缆原因,并根据试验结果进一步提出一些增强光缆耐电腐蚀的措施。 All-dielectric self-supporting (ADSS) cable has the advantages of good insulation, high tensile strength, and power line with the pole tower erection, but there is a defect of electro-corrosion. The principle of resistance corrosion test of ADSS optical cable is introduced, and the resistance corrosion test of ADSS optical cable is designed according to IEEE P1222 test standard. After 1000 hours of salt spray test, the corrosion degree and surface leakage current of ADSS cable surface at the scene of cable breakage accident were analyzed to find out the reason of cable breakage. Based on the test results, some measures to enhance the corrosion resistance of optical fiber cable were put forward.
