摘　　要：为了提升电力光纤复合架空地线(OPGW)的纤芯容量,研制了180 μm细径单模光纤,从光纤剖面结构设计、优化涂层技术2个方面展开研究,并对180 μm细径OPGW光缆进行衰减、应力-应变、环境等性能验证。实验结果表明:180 μm细径光纤在成缆过程中整体光纤的衰减平稳;光缆拉伸应力-应变性能以及光缆环境性能满足且优于OPGW光缆的电力行业标准要求,具备稳定可靠性及实际应用可行性。In order to enhance the core capacity of optical fiber composite overhead ground wire(OPGW),a 180μm fine diame-ter single-mode optical fiber was developed.Research was conducted from two aspects:fiber profile structure design and opti-mized coating technology.The attenuation,stress-strain,and environmental performance of the 180μm fine diameter OPGW op-tical cable were verified.The experimental results show that the attenuation of the entire 180μm fine diameter fiber is stable dur-ing the cabling process.The tensile stress-strain performance and environmental performance of optical cables meet and exceed the power industry standard requirements of OPGW cables,and have stable reliability and practical application feasibility.
