摘要
目前,国内生产的OPGW主要为不锈钢管结构,但如果要求OPGW的截面积或缆直径较小而短路电流较大,其选型比较困难。文章详细分析了钢管和铝包钢管OPGW的结构特点和相关参数,通过比较认为:铝包钢管OPGW可补充钢管OPGW结构系列中的不连续区段,但当OPGW的外径、截面积足够大且外层股线直径也足够大的情况下,铝包钢管结构并不具优势。
At present, domestic made OPGW is mainly steel structure. It will cause difficulty when making the selection for smaller cross-sectional area or diameter and bigger short-circuits OPGW. By analyzing and comparing the structure characteristics and relevant parameters between steel tube type OPGW and aluminum cladding steel tube type OPGW, this paper finds out that aluminum cladding steel tube structure OPGW is a good supplement to the steel tube structure OPGW in the regions where the steel tube structure OPGW is not suitable, but for OPGW with enough large diameter, cross-section area and outer layer wire diameter, the aluminum cladding steel tube structure OPGW does not have advantages.
