摘要
宁东—山东±660 kV输电线路工程采用4分裂JL/G3A-1000/45-72/7型导线,此型导线在我国第1次运用在超高压输电线路上,由于导线的直径和比重大,在张力放线施工中对工机具要求较高。本文针对工机具的选型进行了验算论证;简述了JL/G3A-1000/45-72/7型导线在张力放线过程中的重点部位施工方案;结合实际放线情况进行了技术经济分析。
Ningdong-Shandong ±660 kV power transmission line project is used 4 split JL/G3A-1000/45-72/7 conductor line,which is first applied in domestic EHV transmission line.Due to the diameter and density of conductor line is large,it has high demand for the construction operation devices in the tension stringing.Aiming at selection of the type of working devices,makes calculation and verification,describes the key parts construction schemes of JL/G3A-1000/45-72/7 conductor in the process of the tension stringing,combining with the practical situation makes technological and economic analysis.
