±800 kV云广特高压直流线路工程采用6分裂大截面导线，采用“一牵4+一牵2”同步展放方式经济合理，但每相须挂2个导线放线滑车。介绍了利用导线六联板作滑车挂点的双滑车悬挂新方法。

The wires with large cross section and 6 fissions are applied in ±800 kV Yunnan-Guangdong ultra-high voltage DC transmission line project. It is shown that the synchronized exhibition of one-pulling-four combined with one-pulling-two is economic and reasonable. However, each phase must hang two pulleys for exhibiting the wires. Therefore, a new method for double pulley hanging wires is proposed where the six joint board of the wire is used as the pulley hanging point.
