    我(wo)國(guo)(guo)應(ying)用鋁(lv)芯和鋁(lv)合金(jin)(jin)(jin)(jin)芯電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)進展(zhan)與(yu)美(mei)國(guo)(guo)相比有很大(da)(da)差(cha)距.在我(wo)國(guo)(guo)的(de)(de)(de)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)產品(pin)(pin)(pin)(pin)研發(fa)中,電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)安裝敷(fu)設金(jin)(jin)(jin)(jin)具的(de)(de)(de)研制,總是(shi)(shi)(shi)落(luo)后(hou)于電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)本身的(de)(de)(de)研發(fa)進度.例如(ru)(ru),由于架(jia)(jia)空(kong)絕(jue)緣電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)架(jia)(jia)設金(jin)(jin)(jin)(jin)具落(luo)后(hou),嚴重妨(fang)礙了(le)(le)架(jia)(jia)空(kong)絕(jue)緣的(de)(de)(de)推廣(guang)和出(chu)口.世界上出(chu)口架(jia)(jia)空(kong)絕(jue)緣電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)最多的(de)(de)(de)國(guo)(guo)家是(shi)(shi)(shi)芬蘭,他們(men)都是(shi)(shi)(shi)與(yu)架(jia)(jia)設金(jin)(jin)(jin)(jin)具一起出(chu)口的(de)(de)(de).這一現象,至今(jin)(jin)依然不同程度的(de)(de)(de)存(cun)在著(zhu).如(ru)(ru)今(jin)(jin)鋁(lv)合金(jin)(jin)(jin)(jin)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)發(fa)展(zhan),同樣存(cun)在配套(tao)金(jin)(jin)(jin)(jin)具(連接附(fu)件產品(pin)(pin)(pin)(pin))技(ji)術滯(zhi)后(hou)的(de)(de)(de)的(de)(de)(de)大(da)(da)問(wen)題.這嚴重制約了(le)(le)鋁(lv)合金(jin)(jin)(jin)(jin)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)推廣(guang)應(ying)用.據了(le)(le)解(jie),目前在國(guo)(guo)內的(de)(de)(de)鋁(lv)合金(jin)(jin)(jin)(jin)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)企業中,除業內領(ling)軍品(pin)(pin)(pin)(pin)牌上善星(xing)合金(jin)(jin)(jin)(jin)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)等極少(shao)數優秀品(pin)(pin)(pin)(pin)牌具備(bei)了(le)(le)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)產品(pin)(pin)(pin)(pin)生(sheng)產、鋁(lv)合金(jin)(jin)(jin)(jin)連接端(duan)子附(fu)件生(sheng)產等綜(zong)合能力(li)(li),稱得上是(shi)(shi)(shi)真正鋁(lv)合金(jin)(jin)(jin)(jin)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)全套(tao)技(ji)術產品(pin)(pin)(pin)(pin)提(ti)供(gong)商外,業內目前大(da)(da)多數企業尚不具備(bei)提(ti)供(gong)全套(tao)產品(pin)(pin)(pin)(pin)的(de)(de)(de)能力(li)(li).

    鋁(lv)(lv)合金電(dian)(dian)纜(lan)錯誤連接方(fang)案即(ji)目(mu)前國內在鋁(lv)(lv)合金電(dian)(dian)纜(lan)連接時(shi)使用原(yuan)用于鋁(lv)(lv)電(dian)(dian)纜(lan)的(de)銅鋁(lv)(lv)過(guo)渡端子等鋁(lv)(lv)連接器(qi)和(he)與(yu)電(dian)(dian)纜(lan)性能不一致的(de)鋁(lv)(lv)合金連接器(qi)作為連接方(fang)案.這種(zhong)連接方(fang)案將留下安(an)全(quan)隱患,使鋁(lv)(lv)合金電(dian)(dian)纜(lan)的(de)優(you)勢(shi)和(he)價值蕩然無存,應用鋁(lv)(lv)合金電(dian)(dian)纜(lan)將變得毫無優(you)勢(shi)和(he)價值.

   ; 鋁(lv)合金電纜必須使用鋁(lv)合金專用端子(zi)的五大理由:

    第(di)一大理由(you):銅(tong)鋁(lv)(lv)(lv)過渡端子(zi)因端子(zi)中鋁(lv)(lv)(lv)的(de)(de)存在,所有鋁(lv)(lv)(lv)的(de)(de)缺陷與不(bu)足的(de)(de)問題依然存在,這種端子(zi)用于連接鋁(lv)(lv)(lv)合(he)金(jin)電(dian)纜,則鋁(lv)(lv)(lv)合(he)金(jin)電(dian)纜的(de)(de)優(you)勢和(he)價(jia)值蕩然無存,還(huan)不(bu)如直接使用鋁(lv)(lv)(lv)電(dian)纜,因鋁(lv)(lv)(lv)電(dian)纜更經(jing)濟.使用鋁(lv)(lv)(lv)合(he)金(jin)專用端子(zi)就能充(chong)分發(fa)揮鋁(lv)(lv)(lv)合(he)金(jin)電(dian)纜的(de)(de)優(you)勢和(he)價(jia)值.

    第二大(da)理由:銅(tong)鋁(lv)過渡端(duan)子(zi)因原是用(yong)于連(lian)接(jie)(jie)(jie)鋁(lv)電纜,端(duan)子(zi)安(an)裝尺寸與終端(duan)設備尺寸不匹(pi)配,不僅增(zeng)加轉接(jie)(jie)(jie)銅(tong)牌等費用(yong),轉接(jie)(jie)(jie)銅(tong)牌多(duo)道(dao)轉接(jie)(jie)(jie),也(ye)將留下連(lian)接(jie)(jie)(jie)安(an)全隱患.使用(yong)鋁(lv)合金專用(yong)端(duan)子(zi)就可(ke)以避免類(lei)似問題.

    第三(san)大理由:因銅鋁過(guo)渡連接端子與電(dian)氣終端不匹配(pei),增(zeng)加轉接銅牌而經常產生(sheng)費(fei)用(yong)(yong)的矛盾(dun),以(yi)至難以(yi)避免因這類問題無法解決而發生(sheng)野蠻施工帶(dai)來的連接安全隱(yin)患.使(shi)用(yong)(yong)鋁合金專用(yong)(yong)端子就可(ke)以(yi)避免類似問題.

    第四大理由:銅鋁(lv)過(guo)渡端(duan)(duan)子因原(yuan)是用(yong)于連(lian)接(jie)(jie)鋁(lv)電(dian)纜,這種端(duan)(duan)子內(nei)徑與電(dian)纜導體(ti)外徑不(bu)匹配,必(bi)須使用(yong)專用(yong)壓接(jie)(jie)工具,造成難以規范(fan)施工,留下連(lian)接(jie)(jie)安(an)全隱患.使用(yong)鋁(lv)合金(jin)專用(yong)端(duan)(duan)子就可以避(bi)免類似問(wen)題.

    第五大理(li)(li)由:目前(qian)市場上(shang)使(shi)用的(de)各種(zhong)品牌(pai)銅(tong)鋁(lv)(lv)(lv)(lv)(lv)(lv)過(guo)渡(du)端(duan)(duan)子(zi)中(zhong)(zhong)鋁(lv)(lv)(lv)(lv)(lv)(lv)的(de)純(chun)度(du)最多只能(neng)(neng)達99.5%(注:一般電(dian)工(gong)鋁(lv)(lv)(lv)(lv)(lv)(lv)純(chun)度(du)都在99.7%以(yi)(yi)上(shang)).而且制造銅(tong)鋁(lv)(lv)(lv)(lv)(lv)(lv)過(guo)渡(du)端(duan)(duan)子(zi)中(zhong)(zhong)的(de)鋁(lv)(lv)(lv)(lv)(lv)(lv),還是導(dao)(dao)電(dian)率(lv)(lv)(lv)(lv)比較(jiao)差的(de)經固熔與(yu)淬火處理(li)(li)的(de)工(gong)業鋁(lv)(lv)(lv)(lv)(lv)(lv),所以(yi)(yi)這些銅(tong)鋁(lv)(lv)(lv)(lv)(lv)(lv)過(guo)渡(du)端(duan)(duan)子(zi)的(de)綜合(he)(he)導(dao)(dao)電(dian)率(lv)(lv)(lv)(lv)只能(neng)(neng)在54%IACS以(yi)(yi)下(xia)(注:導(dao)(dao)體(ti)鋁(lv)(lv)(lv)(lv)(lv)(lv)合(he)(he)金導(dao)(dao)電(dian)率(lv)(lv)(lv)(lv)要求在61%IACS以(yi)(yi)上(shang)),這造成端(duan)(duan)子(zi)與(yu)鋁(lv)(lv)(lv)(lv)(lv)(lv)合(he)(he)金電(dian)纜電(dian)氣(qi)性(xing)能(neng)(neng)不匹配,結果是傳(chuan)輸(shu)線路(lu)電(dian)阻率(lv)(lv)(lv)(lv)增大21%以(yi)(yi)上(shang),線路(lu)傳(chuan)輸(shu)能(neng)(neng)力(li)下(xia)降21%或增加線路(lu)損耗(hao)達21%以(yi)(yi)上(shang).使(shi)用鋁(lv)(lv)(lv)(lv)(lv)(lv)合(he)(he)金專用端(duan)(duan)子(zi)就能(neng)(neng)夠充分發揮使(shi)用鋁(lv)(lv)(lv)(lv)(lv)(lv)合(he)(he)金電(dian)纜進行電(dian)力(li)傳(chuan)輸(shu)的(de)能(neng)(neng)力(li).

    至于(yu)(yu)與AA-8000導體鋁(lv)合(he)金(jin)性(xing)能(neng)(neng)不一(yi)致的其它鋁(lv)合(he)金(jin)端子,由于(yu)(yu)其材料(liao)的物理、機械(xie)、電氣、抗壓蠕變(bian)等性(xing)能(neng)(neng)與AA-8000導體鋁(lv)合(he)金(jin)性(xing)能(neng)(neng)存在(zai)差異,若這(zhe)樣的端子用(yong)于(yu)(yu)鋁(lv)合(he)金(jin)電纜(lan)連接,將帶來的安全隱患等問題(ti)就(jiu)不言而喻了.

    所以,用戶和相關行業人員必須清楚了(le)解的事(shi)實是:

    要保證鋁合(he)金(jin)電纜(lan)(lan)的優勢和價值(zhi)得以發揮和體(ti)現,安(an)全、無隱(yin)患應用(yong)鋁合(he)金(jin)電纜(lan)(lan)的前提是:符合(he)標準要求(qiu)的鋁合(he)金(jin)電纜(lan)(lan)加上與電纜(lan)(lan)性能一致的配套鋁合(he)金(jin)連接器共同使(shi)用(yong).

    目(mu)前(qian)國內(nei)鋁(lv)(lv)(lv)合(he)(he)金(jin)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)行業(ye)(ye)中只(zhi)有(you)具(ju)有(you)北(bei)(bei)美(mei)背(bei)(bei)景(jing)(jing)、曾從北(bei)(bei)美(mei)帶(dai)入成熟鋁(lv)(lv)(lv)合(he)(he)金(jin)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)技術和(he)先進(jin)生(sheng)(sheng)產工藝、以堅持只(zhi)做精(jing)品享譽業(ye)(ye)內(nei)的(de)(de)(de)領(ling)軍品牌上(shang)善(shan)星合(he)(he)金(jin)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)等(deng)極少數(shu)優秀品牌不等(deng)不靠,克服了(le)國內(nei)無鋁(lv)(lv)(lv)合(he)(he)金(jin)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)專用連接器供(gong)應鏈的(de)(de)(de)困(kun)難,開發出(chu)與電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)性(xing)能(neng)一致的(de)(de)(de)鋁(lv)(lv)(lv)合(he)(he)金(jin)連接端(duan)子(zi)(zi),完善(shan)了(le)鋁(lv)(lv)(lv)合(he)(he)金(jin)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)應用條件(jian),秉(bing)承了(le)北(bei)(bei)美(mei)等(deng)國家的(de)(de)(de)規(gui)范做法(fa).在(zai)當前(qian)國內(nei)無法(fa)形成專業(ye)(ye)的(de)(de)(de)鋁(lv)(lv)(lv)合(he)(he)金(jin)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)連接配套端(duan)子(zi)(zi)等(deng)附件(jian)的(de)(de)(de)生(sheng)(sheng)產、供(gong)應鏈的(de)(de)(de)現實背(bei)(bei)景(jing)(jing)下,鋁(lv)(lv)(lv)合(he)(he)金(jin)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)企業(ye)(ye)的(de)(de)(de)當務之(zhi)(zhi)急(ji)就是要(yao)走(zou)自力更生(sheng)(sheng)之(zhi)(zhi)路(lu),先自己解(jie)決鋁(lv)(lv)(lv)合(he)(he)金(jin)連接端(duan)子(zi)(zi)的(de)(de)(de)生(sheng)(sheng)產、配套問題,不等(deng)不靠,面對現實.為(wei)了(le)行業(ye)(ye)、企業(ye)(ye)可(ke)持續健康發展(zhan),業(ye)(ye)內(nei)企業(ye)(ye)要(yao)直(zhi)面現實.
