8000系列鋁合金導體電纜或可取代銅纜

“8000系列鋁合金導體電纜或許可以取代銅纜。”這是近日從在天津舉行的2013年亞洲線纜論壇暨2013年(第二十三屆)全國電線電纜專用設備展銷、技術交流及采購訂貨會議上傳來的消息。

據專家介紹:當前中國銅資源緊缺,電線電纜行業內很多人都提倡以鋁代銅。但是純鋁電纜也有它的很多不足之處,而鋁合金電力電纜彌補了它的很多不足之處:提高了電纜的導電性能、彎曲性能、抗蠕變性能和耐腐蝕性能等,能夠保證電纜在長時間過載和過熱時保持連續性能穩定。如果采用8000系列鋁合金導體制造電纜的話那又是一個不小的提升,它不僅可以大大提高鋁合金電纜的導電率、耐高溫性,同時也能夠解決純鋁導體電化學腐蝕、蠕變等問題。8000系鋁合金的導電率是最常用基準材料銅IACS(導電率百分值)的61%,在同樣體積下,鋁合金的實際重量大約是銅的三分之一。按照該計算,在滿足相同導電性能的前提下,相同重量下8000系列鋁合金電纜的長度是銅電纜的兩倍。因此,相同載流量時8000系鋁合金導體電纜的重量大約是銅纜的一半。

除此之外,由于8000系列的鋁合金導體電纜的重量輕,將使運輸、安裝過程中碳排量大量減少。同時,8000系列的鋁合金導體電纜不含重金屬元素,綠色環保。可以說8000系列的鋁合金導體電纜是一種節能、節材、環保的電纜,在中國銅資源越來越緊缺的大環境之下,它或許可以取代銅電纜。
