摘要
在宁东-山东±660 kV直流输电示范工程晋3标段施工中,通过研究运用2×(一牵二)同步展放1 000mm2大截面导线施工技术,重点阐述了放线机械及施工器具选用、滑车选择及悬挂方式、导引绳及牵引绳展放方法、张牵场选择及布置以及导线同步展放的技术措施,解决了1 000 mm2大截面导线同步展放施工难题。
In the construction of Jin section 3 of Ningdong - Shandong ± 660 kV dc transmission demonstration project, on the basis of the research on 2 × （one -pull- two） synchronized tension pay -off technology of conductors with 1 000 mm^2 section, this paper prominently introduces the selection of pay - off mechanism and construction ap- paratus, the selection and hang of tackles, pay - off method of leading rope and stringing rope, the selection and layout of tension stringing field and the synchronized tension pay - off technology of conductors, which solves the problems of the construction of synchronized pay - off of conductors with 1 000 mm^2 section.
