Abstract: This paper introduces a new-type PE coating wire line used in aerial crossing of pipeline. In the past, the wife line with different specifications were taken as load line and wind line, which was difficult to the design and construction of aerial crossing of pipelines due to the limited performances of wire line itself. A new-type PE coating wire line is successfully developed by Huaneng Thermal Electricity Co. Ltd. of Suzhou. This kind of wire line can be used as load line and wind line of pipeline bridge. And this wire line is adopted in two pipeline bridges in Jiansu Province.
