一、鋁合金電纜能用銅鋁過渡線鼻子嗎
銅鋁過渡線鼻子是一種具有良好導電性的金屬材料,主要作用是將兩種不同金屬的導線連接起來,以確保電流的正常傳遞。相對于其他過渡線鼻子,銅鋁過渡線鼻子具有價格低廉、外觀美觀、耐腐蝕、導電性能好等優點。那么鋁合金電纜能用銅(tong)鋁(lv)過(guo)渡線(xian)鼻(bi)子(zi)嗎?
鋁合金(jin)電纜使用(yong)銅鋁過渡(du)線鼻子(zi)(zi)并不可行,使用(yong)銅鋁過渡(du)線鼻子(zi)(zi)連接(jie)鋁合金(jin)電纜存在以下問題:
1、導電性能降低。鋁合金電纜是一種高電阻材料,與銅(tong)鋁過渡線鼻(bi)子的連接會產生接觸電阻,導致電流(liu)傳(chuan)輸效率降低。
2、易產生氧化。鋁(lv)合金電纜(lan)與(yu)銅鋁(lv)過渡線鼻子連接時,會(hui)受到空氣中(zhong)的氧(yang)化作用(yong),從而導致氧(yang)化膜的產(chan)生,降(jiang)低接觸性能。
3、腐蝕問題。銅(tong)鋁過(guo)渡(du)線鼻子(zi)對于電(dian)(dian)解質的(de)腐蝕能力較(jiao)強(qiang),而鋁合(he)金(jin)電(dian)(dian)纜內(nei)部含有(you)電(dian)(dian)解質,易被銅(tong)鋁過(guo)渡(du)線鼻子(zi)腐蝕,從而導致鼻子(zi)失效。
二、鋁合金電纜用什么接線端子
鋁合(he)(he)金電纜(lan)的應(ying)用,在連(lian)接(jie)(jie)時應(ying)采用與所連(lian)接(jie)(jie)的鋁合(he)(he)金電纜(lan)相同化學(xue)成分,電氣、物理、機(ji)械、抗(kang)壓蠕變等性(xing)能一致的鋁合(he)(he)金銅專(zhuan)用連(lian)接(jie)(jie)器。這樣(yang)鋁合(he)(he)金電纜(lan)與連(lian)接(jie)(jie)器的性(xing)能一致,才能達(da)到巧妙連(lian)接(jie)(jie),真的實現使用鋁合(he)(he)金電纜(lan)的優勢和(he)價值。
專用(yong)鋁合金銅(tong)連(lian)接端(duan)(duan)(duan)(duan)(duan)子用(yong)于連(lian)接終(zhong)端(duan)(duan)(duan)(duan)(duan)設備的銅(tong)連(lian)接端(duan)(duan)(duan)(duan)(duan),在連(lian)接尺(chi)寸(cun)、電氣性(xing)能上要完(wan)全(quan)與(yu)連(lian)接終(zhong)端(duan)(duan)(duan)(duan)(duan)設備的尺(chi)寸(cun)、性(xing)能匹配,不再需(xu)要轉接銅(tong)牌等方式多道轉接,保證與(yu)終(zhong)端(duan)(duan)(duan)(duan)(duan)的安全(quan)連(lian)接,這樣就可(ke)完(wan)全(quan)杜絕、避免因端(duan)(duan)(duan)(duan)(duan)子無法與(yu)終(zhong)端(duan)(duan)(duan)(duan)(duan)匹配而消磨端(duan)(duan)(duan)(duan)(duan)子連(lian)接面等野蠻(man)施工帶來(lai)的安全(quan)隱患(huan)。
專用鋁合金銅連接端子及其它附件,其連接鋁合金電纜的(de)鋁(lv)合金端(duan)的(de)內徑(jing)與電纜導體(ti)外(wai)徑(jing)要零公差配合,減(jian)少(shao)壓接(jie)工(gong)(gong)(gong)具壓力需求;端(duan)子(zi)外(wai)徑(jing)與傳(chuan)統壓接(jie)銅纜的(de)工(gong)(gong)(gong)具匹配,工(gong)(gong)(gong)程施工(gong)(gong)(gong)不再使用鋁(lv)合金電纜壓接(jie)專用工(gong)(gong)(gong)具,直接(jie)使用銅纜壓接(jie)工(gong)(gong)(gong)具,與銅纜壓接(jie)一樣方便、可靠(kao),方便規范(fan)施工(gong)(gong)(gong),有效地(di)提高電纜連(lian)接(jie)施工(gong)(gong)(gong)質量。
