    <p style="text-indent: 2em; line-height: 3em;"><span style="font-size: 20px; font-family: 宋体, SimSun;">11月5日，南方电网公司首次在500千伏输电线路实现了八分裂导线技术工艺的新突破。在广东电网重点项目——粤港澳大湾区500千伏外环东段（汕尾段）工程顺利实现了该“八分裂”导线展放技术的首秀。</span></p><p style="text-indent: 2em; line-height: 3em;"><span style="font-size: 20px; font-family: 宋体, SimSun;">本工程新建500千伏汕尾开关站与500千伏承龙（苏区）至汕尾线路（A、B线）、500千伏汕尾至陆丰线路（C、D线）共四条单回输电线路，线路总长121.6公里，新建铁塔240基，全线使用八分裂导线。首段放线在平行走线的A、B两条线路上同时开展。</span></p><p style="text-indent: 2em; line-height: 3em;"><span style="font-size: 20px; font-family: 宋体, SimSun;">面对南网系统内首次500千伏八分裂导线的施工，公司高度重视并全盘投入到建设当中，抽调经验丰富的技术管理人员，推演八分裂导线展放施工过程的重、难点，反复论证，不断优化施工技术、创新施工工艺。</span></p><p style="text-indent: 2em; line-height: 3em;"><span style="font-size: 20px; font-family: 宋体, SimSun;">本段架线施工在A、B线上同时开展，且均为八分裂导线，所需施工人员及施工机械均为500千伏线路四分裂导线的四倍。对此，公司提前策划，积极筹备人力物力资源，确保施工人员与施工机械提前进场。</span></p><p style="text-indent: 2em; line-height: 3em;"><span style="font-size: 20px; font-family: 宋体, SimSun;">同时，根据施工场地实际情况优化施工场地布置，11台张力机，8台牵引机等施工工器具摆放错落有致。在施工人员及施工工器具成倍增加的情况下不额外占用场地，尽最大努力减少对生态环境的破坏。</span></p><p style="text-indent: 2em; line-height: 3em;"><span style="font-size: 20px; font-family: 宋体, SimSun;">公司根据八分裂导线展放的实际需求，与汕尾供电局提前进行针对性部署，通过科技创新，自主设计、加工了可同时悬挂两台五轮滑车的连板，打破了传统连板只有一个滑车挂点的局限，从而实现“2×一牵四”的牵引模式，对八根导线进行同步展放，为该项新技术工艺在后续工程的高质量建设，打下扎实基础。</span></p><p><br/></p>  </div>
