[Introduction] In order to solve the problem of heavy load 220 kV transmission line loss. [Methods] Based on the development of large cross-section conductor technology and new materials, a new type of single large cross-section conductor was proposed to replace the conventional double split conductor in the heavy-duty 220 kV transmission line. The 220 kV transmission line with heavy load adopts a new type of single large section energy-saving conductor, which can greatly save power loss and reduce annual cost. [Results] Taking the 220 kV new transmission line project from Tafeng to Linwu with high transmission capacity as an example, the technical differences between the new large section single conductor and the conventional double bundle conductor in terms of electrical and mechanical characteristics are compared and analyzed, and the economy is evaluated by using the annual cost method. [Conclusion] The calculation results demonstrate the feasibility of using new large section single conductor instead of double bundle conductor in heavy load line, and provide reference for the popularization and application of large section conductor. |
