输电线路的节能增效技术是特高压电网和智能电网的技术要求之一.通过对比研究国内外输电技术应用发展,提出为大幅度提高单位输电线路的送电能力和充分利用输电线路走廊,不仅需应用特高压输变电技术、多分裂大截面导线技术及大容量增容导线技术,还应大力推广应用铝合金芯铝绞线、中强度铝合金导线及型线导线等节能导线,以及光纤复合架空地线(OPGW)分段绝缘和光纤线路监测等输电线路节能增效新技术,从而推进输电导线和地线产品的升级换代.%The technology of energy saving and efficiency improvement is required by UHV grids and smart grids. After comparison between related researches and developments both in China and abroad, directions are recommended in order to greatly improve the power transmission capacity and efficiency nf power transmission corridors. In addition to applications of UHV transmission technology, large area-bundled conductor technology and targe capacity uprating conductor technology, us well as other new energy saving and efficiency improvements in materials and technologies, are also worth attention. Combined with new technologies such as OPGW sectional insulation and optical online monitoring, some new conductor materials including aluminium conductors with aluminium alloy reinforced, medium strength aluminium alloy and formed conductors, can be used to promote conductor upgrade and manufacturing progress.
