摘　　要：介绍了铝基陶瓷纤维芯铝绞线(ACCR)的特点及其在冰雪环境下的使用情况,并对导线进行了多年的现场试验。结果表明:试验数据与模型理论计算得到的应力弧垂基本相同;在风载荷、低温以及履冰情况下,导线的性能与计算值基本一致;验证了实验室测试结果的准确性及长期运行的可靠性。3M ACCR （Aluminum Conductor Composite Reinforced ） is a new overhead transmission conductor. The features and iced area application test were introduced in this paper. The produced data closely matched the model-predicted values for sag and tension responses. Test results over the last four years validate the laboratory and model results and demonstrate that the conductor and accessories perform well in ice, extreme cold and wind conditions.
