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鋁過渡線鼻子嗎?
鋁(lv)合金電(dian)纜使用銅(tong)鋁(lv)過(guo)渡(du)線鼻子并(bing)不可(ke)行,使用銅(tong)鋁(lv)過(guo)渡(du)線鼻子連接鋁(lv)合金電(dian)纜存在以下問題(ti):
1、導電性能降低。鋁合金電(dian)纜是一種高電(dian)阻材料(liao),與銅鋁過渡線(xian)鼻子(zi)的連接(jie)會產生接(jie)觸電(dian)阻,導致電(dian)流傳輸效率降低。
2、易產生氧化。鋁(lv)合金電纜與(yu)銅鋁(lv)過(guo)渡線鼻子(zi)連接(jie)(jie)時,會(hui)受到空氣中的(de)氧化(hua)作(zuo)用,從(cong)而導致氧化(hua)膜的(de)產生,降低接(jie)(jie)觸性(xing)能(neng)。
3、腐蝕問題。銅(tong)(tong)鋁過(guo)(guo)渡線鼻子(zi)對于電解質(zhi)的腐蝕(shi)能力較強,而鋁合(he)金電纜內部含有電解質(zhi),易被銅(tong)(tong)鋁過(guo)(guo)渡線鼻子(zi)腐蝕(shi),從(cong)而導致鼻子(zi)失(shi)效。
二、鋁合金電纜用什么接線端子
鋁(lv)合(he)金電纜(lan)(lan)的應用,在連(lian)(lian)接時應采(cai)用與所連(lian)(lian)接的鋁(lv)合(he)金電纜(lan)(lan)相同化學成(cheng)分,電氣、物理(li)、機械、抗壓蠕變等性能一致的鋁(lv)合(he)金銅(tong)專(zhuan)用連(lian)(lian)接器。這(zhe)樣鋁(lv)合(he)金電纜(lan)(lan)與連(lian)(lian)接器的性能一致,才能達到巧妙連(lian)(lian)接,真的實現(xian)使用鋁(lv)合(he)金電纜(lan)(lan)的優勢(shi)和價值。
專用鋁合金銅(tong)連(lian)接(jie)端(duan)(duan)(duan)(duan)子用于連(lian)接(jie)終端(duan)(duan)(duan)(duan)設備的(de)銅(tong)連(lian)接(jie)端(duan)(duan)(duan)(duan),在連(lian)接(jie)尺寸(cun)、電氣性能上要完全(quan)(quan)與連(lian)接(jie)終端(duan)(duan)(duan)(duan)設備的(de)尺寸(cun)、性能匹(pi)配(pei),不再需要轉接(jie)銅(tong)牌等方式多道轉接(jie),保證與終端(duan)(duan)(duan)(duan)的(de)安(an)全(quan)(quan)連(lian)接(jie),這(zhe)樣(yang)就可完全(quan)(quan)杜(du)絕、避免因端(duan)(duan)(duan)(duan)子無法與終端(duan)(duan)(duan)(duan)匹(pi)配(pei)而消磨端(duan)(duan)(duan)(duan)子連(lian)接(jie)面等野蠻施工帶來的(de)安(an)全(quan)(quan)隱(yin)患。
專用鋁合金銅連接端子及其它附件,其連接鋁合金電纜的鋁合(he)金端的內(nei)徑(jing)與(yu)電(dian)纜(lan)(lan)(lan)(lan)導體外(wai)徑(jing)要零(ling)公差配(pei)合(he),減少壓(ya)接(jie)(jie)(jie)(jie)工(gong)(gong)(gong)(gong)具(ju)壓(ya)力需求;端子(zi)外(wai)徑(jing)與(yu)傳(chuan)統(tong)壓(ya)接(jie)(jie)(jie)(jie)銅纜(lan)(lan)(lan)(lan)的工(gong)(gong)(gong)(gong)具(ju)匹(pi)配(pei),工(gong)(gong)(gong)(gong)程施(shi)工(gong)(gong)(gong)(gong)不再(zai)使用(yong)鋁合(he)金電(dian)纜(lan)(lan)(lan)(lan)壓(ya)接(jie)(jie)(jie)(jie)專(zhuan)用(yong)工(gong)(gong)(gong)(gong)具(ju),直接(jie)(jie)(jie)(jie)使用(yong)銅纜(lan)(lan)(lan)(lan)壓(ya)接(jie)(jie)(jie)(jie)工(gong)(gong)(gong)(gong)具(ju),與(yu)銅纜(lan)(lan)(lan)(lan)壓(ya)接(jie)(jie)(jie)(jie)一樣方(fang)便、可(ke)靠,方(fang)便規范施(shi)工(gong)(gong)(gong)(gong),有效地提(ti)高電(dian)纜(lan)(lan)(lan)(lan)連接(jie)(jie)(jie)(jie)施(shi)工(gong)(gong)(gong)(gong)質量(liang)。
