特高壓“鋼需”持(chi)續(xu)增長

目前，特(te)(te)(te)高壓(ya)建(jian)(jian)設(she)(she)(she)工(gong)(gong)程的(de)開工(gong)(gong)復(fu)(fu)工(gong)(gong)正在加快，2月28日開工(gong)(gong)的(de)陜北—湖北的(de)±800千伏特(te)(te)(te)高壓(ya)直(zhi)流工(gong)(gong)程是 電(dian)網(wang)今年 新開工(gong)(gong)的(de)特(te)(te)(te)高壓(ya)工(gong)(gong)程，其總投(tou)資(zi)金額(e)185億元(yuan)，預計(ji)可直(zhi)接帶動(dong)設(she)(she)(she)備(bei)生產(chan)規模約(yue)120億元(yuan)，帶動(dong)電(dian)源等相關產(chan)業(ye)投(tou)資(zi)超過700億元(yuan)；而且，截(jie)止到3月中旬，青(qing)海-河南(nan)、東吳擴建(jian)(jian)、張北-雄安(an)、蒙西-晉中、駐馬店-南(nan)陽、長治擴建(jian)(jian)特(te)(te)(te)高壓(ya)交流工(gong)(gong)程等共8項特(te)(te)(te)高壓(ya)工(gong)(gong)程復(fu)(fu)工(gong)(gong)，這將(jiang)有(you)力(li)(li)拉動(dong)電(dian)源、電(dian)工(gong)(gong)裝備(bei)、用(yong)(yong)能設(she)(she)(she)備(bei)、原(yuan)材料等上下游企業(ye)復(fu)(fu)工(gong)(gong)復(fu)(fu)產(chan)，從而加快特(te)(te)(te)高壓(ya)產(chan)業(ye)鏈上的(de)鋼(gang)(gang)(gang)材需求快速恢復(fu)(fu)。特(te)(te)(te)高壓(ya)項目工(gong)(gong)程建(jian)(jian)設(she)(she)(she)所(suo)需鋼(gang)(gang)(gang)材一般分為電(dian)力(li)(li)鐵塔用(yong)(yong)鋼(gang)(gang)(gang)和取向電(dian)工(gong)(gong)鋼(gang)(gang)(gang)，電(dian)力(li)(li)鐵塔用(yong)(yong)鋼(gang)(gang)(gang)主要包括：角鋼(gang)(gang)(gang)、鋼(gang)(gang)(gang)板(ban)、鋼(gang)(gang)(gang)管、槽(cao)鋼(gang)(gang)(gang)等；型(xing)鋼(gang)(gang)(gang)的(de)材質一般為Q355C 號鋼(gang)(gang)(gang)等，但隨著(zhu)特(te)(te)(te)高壓(ya)輸(shu)電(dian)線路項目高標準(zhun)的(de)實施(shi)，Q355、Q390、Q420、Q460 等高強(qiang)度鋼(gang)(gang)(gang)材也(ye)在逐漸被采(cai)用(yong)(yong)。
