(1.No.8 Detachment No.2 Hydropoteer Force of Armed Police Xiamen Fujian 361009 China; 2.No.2 Hydropower Force of Armed Police Nanchang Jiangxi 330096 China) Abstract:One thousand square millimeters large cross-section wire is used in some new constructed ±660 kV direct current transmission line.The structure and construction technology are significantly different with traditional expanding wire.Authors introduced key technical points and attention factors of the large cross-section wire mainly from wiring equipment selection tension stringing and wires joint. Through strictly organization the construction task is successfully pleted.
