一、鋁合金電纜可以用于小區嗎
鋁合金電纜在小(xiao)區(qu)(qu)配電(dian)(dian)(dian)(dian)(dian)(dian)中是(shi)可(ke)行的選擇,鋁(lv)合(he)(he)金電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)重量輕(qing)、成本低(di)(di)、導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)性能良好(hao),其傳輸電(dian)(dian)(dian)(dian)(dian)(dian)力(li)的能力(li)與銅(tong)質電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)相當,適合(he)(he)在小(xiao)區(qu)(qu)等(deng)低(di)(di)壓傳輸線路中使(shi)用。但由于(yu)鋁(lv)合(he)(he)金電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)的焊接(jie)性能比銅(tong)質電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)差,需(xu)(xu)要(yao)特殊的連(lian)接(jie)器材進行連(lian)接(jie)。同時(shi),鋁(lv)合(he)(he)金電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)易受(shou)潮濕、氧化(hua)等(deng)環(huan)(huan)境(jing)因素(su)影響,容(rong)易導(dao)致(zhi)傳輸電(dian)(dian)(dian)(dian)(dian)(dian)力(li)中斷(duan)。考慮(lv)到小(xiao)區(qu)(qu)內復(fu)雜的環(huan)(huan)境(jing)因素(su)以及對電(dian)(dian)(dian)(dian)(dian)(dian)力(li)傳輸的穩(wen)定性要(yao)求高,鋁(lv)合(he)(he)金電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)用于(yu)小(xiao)區(qu)(qu)時(shi)需(xu)(xu)注意以下幾點:
1、在安裝過程中(zhong),鋁合金電纜需要采用專門的(de)連接器(qi)材,并注(zhu)意防潮、防氧化,以防止連接松散、導致電力傳(chuan)輸中(zhong)斷的(de)情況發生。
2、在小(xiao)區內設立配電(dian)箱時,需確保配電(dian)箱符(fu)合(he)國家安全要求(qiu),并由專業技術人員進行施(shi)工安裝,以防止(zhi)因鋁合(he)金電(dian)纜的(de)特點而(er)導致的(de)安全隱患。
3、在小區(qu)內使用鋁合金(jin)電(dian)纜時,需(xu)定期(qi)進行維護檢(jian)修,避免(mian)電(dian)力(li)傳(chuan)輸中斷,保(bao)證小區(qu)居(ju)民的(de)用電(dian)安全。
總體(ti)來(lai)說,鋁合金電纜(lan)在小區的使用是(shi)可行的,但需注意(yi)焊接質(zhi)量、連接器(qi)材(cai)、防(fang)潮(chao)、防(fang)氧化等問題,確保小區電力傳輸的質(zhi)量和安全(quan)。
二、鋁合金電纜不適用于哪些場合
在絕大多數普通場合,例如工廠、住宅、商業建筑、學校、市政民用工程等領域,鋁合金電纜完(wan)全可以取(qu)代銅(tong)纜來(lai)使用(yong)(yong)。而在(zai)一些重要場(chang)所、特(te)殊場(chang)所,例(li)如城市供電(dian)主干線路(lu)、大型電(dian)廠電(dian)站、重污染環境、不易維修(xiu)的環境下,鋁(lv)合金電(dian)纜并非是最(zui)佳選擇。這些場(chang)所突出供電(dian)的安全性(xing)與(yu)可靠性(xing),供電(dian)穩定性(xing)要求非常(chang)高,這種情況下,原本在(zai)普通場(chang)所不存在(zai)的鋁(lv)導體電(dian)纜風險性(xing)問題就(jiu)會凸(tu)顯出來(lai),因(yin)此推薦使用(yong)(yong)安全性(xing)更(geng)高的銅(tong)纜作為第一選擇。
JGJ16-2008《民用(yong)(yong)建(jian)筑(zhu)電(dian)氣設(she)計(ji)(ji)規(gui)(gui)范》7.4 導(dao)體選(xuan)擇(ze)7.4.1 低壓(ya)配電(dian)導(dao)體選(xuan)擇(ze)應符合下(xia)列規(gui)(gui)定:電(dian)纜、電(dian)線可選(xuan)用(yong)(yong)銅(tong)芯或鋁芯,民用(yong)(yong)建(jian)筑(zhu)宜采用(yong)(yong)銅(tong)芯電(dian)纜或電(dian)線;下(xia)列場所應選(xuan)用(yong)(yong)銅(tong)芯電(dian)纜或電(dian)線:1、易(yi)燃、易(yi)爆場所;2、重要(yao)的(de)(de)(de)公(gong)共建(jian)筑(zhu)和居(ju)住建(jian)筑(zhu);3、特別潮濕(shi)場所和對(dui)鋁有(you)腐蝕的(de)(de)(de)場所;4、人員(yuan)聚(ju)集較多的(de)(de)(de)場所;5、重要(yao)的(de)(de)(de)資料室(shi)、計(ji)(ji)算機房(fang)、重要(yao)的(de)(de)(de)庫房(fang);6、移動(dong)設(she)備或有(you)劇烈振動(dong)的(de)(de)(de)場所;7、有(you)特殊規(gui)(gui)定的(de)(de)(de)其他場所。
