摘　　要：随着能源互联网在全球建设的探索和推进,OPGW的架设和使用势必遇到极端低温的考验。文章介绍了一种新型耐极寒OPGW的研制并通过实验室测试对其耐低温性能进行了分析。试验结果表明,通过使用具有较低玻璃化转变温度的光纤涂覆层材料,可以有效降低裸光纤在极端低温下的衰减。在光纤成缆过程中,选取具有较高锥入度的光纤阻水油膏与耐极寒光纤涂覆层材料相互配合,可以保证光纤在-70℃的衰减性能。文章的研究成果为能源互联网在极寒地区建设提供了技术保障。With the global exploration and construction of energy Internet,the installation and use of OPGW might be challenged by extreme low temperature.This paper introduces the research and development of a new type of OPGW and analyzes its performance atextreme low temperature in lab.The tests show that by using coating material with lower glass-transition temperature(GTT),the attenuation of optical fiber could be reduced atextreme low temperature effectively.By cooperatively using filling gel with higher cone penetration and coating materials resistant to extreme low temperature in the manufacture of OPGW,the attenuation of optical fiber could satisfy the requirement of use at–70℃.The research findings of this paper provide technical support for the construction of energy Internet in the areas with extreme low temperature.
