電線(xian)單股和多股的區別

單(dan)股電(dian)線(xian)的每一根(gen)電(dian)線(xian)，是由單(dan)一的一根(gen)粗電(dian)線(xian)組成(cheng)的，又(you)叫(jiao)做硬線(xian)；而多股電(dian)線(xian)的每一根(gen)電(dian)線(xian)，則(ze)是由多個細銅絲組成(cheng)的一根(gen)電(dian)線(xian)，光伏(fu)電(dian)纜(lan)，又(you)叫(jiao)做軟線(xian)。

裝修適合用(yong)單股(gu)(gu)線(xian)(xian)還(huan)是(shi)用(yong)多(duo)股(gu)(gu)線(xian)(xian)？1、施工(gong)方(fang)(fang)面(mian)：多(duo)股(gu)(gu)電(dian)線(xian)(xian)容(rong)易(yi)施工(gong)：由(you)于單股(gu)(gu)線(xian)(xian)是(shi)用(yong)一(yi)(yi)根粗銅(tong)(tong)線(xian)(xian)制作成的(de)，相對(dui)(dui)多(duo)股(gu)(gu)來說，有(you)點(dian)硬，所以(yi)在施工(gong)穿線(xian)(xian)的(de)時候(hou)，相對(dui)(dui)比較(jiao)難穿線(xian)(xian)；而多(duo)股(gu)(gu)的(de)電(dian)線(xian)(xian)，穿線(xian)(xian)的(de)時候(hou)就容(rong)易(yi)多(duo)了。2、散熱方(fang)(fang)面(mian)：多(duo)股(gu)(gu)電(dian)線(xian)(xian)散熱占有(you)一(yi)(yi)定(ding)優勢(shi)多(duo)股(gu)(gu)電(dian)線(xian)(xian)是(shi)由(you)多(duo)個細銅(tong)(tong)絲組成的(de)，銅(tong)(tong)絲與(yu)銅(tong)(tong)絲之間有(you)一(yi)(yi)定(ding)的(de)間隙，所以(yi)散熱方(fang)(fang)面(mian)占有(you)一(yi)(yi)定(ding)的(de)優勢(shi)。3、是(shi)否容(rong)易(yi)氧化：單股(gu)(gu)線(xian)(xian)不(bu)容(rong)易(yi)氧化? 4、價格方(fang)(fang)面(mian)：單股(gu)(gu)線(xian)(xian)價格相對(dui)(dui)便宜

材料的穩定性

一般的(de)二步法交(jiao)聯(lian)(lian)聚乙(yi)烯，首先在和PE發生(sheng)接(jie)枝反應，生(sheng)成可交(jiao)聯(lian)(lian)的(de)PE(簡稱A料(liao))，為了加快(kuai)其(qi)交(jiao)聯(lian)(lian)反應，制成含有催化劑的(de)母(mu)料(liao)(B料(liao))，再將A、B料(liao)按一定(ding)比例進行接(jie)枝，形(xing)成可交(jiao)聯(lian)(lian)的(de)PE。絕緣(yuan)線芯質(zhi)量問題是由材料(liao)穩定(ding)性引起(qi)的(de)主要(yao)原因：

(1)交(jiao)聯聚乙烯絕緣料各(ge)組分混合不均勻，由于(yu)A料中含有交(jiao)聯劑和少量(liang)劑，生產過(guo)程中若劑未(wei)攪拌均勻，將導(dao)致絕緣料通(tong)過(guo)擠(ji)塑(su)機擠(ji)塑(su)后，比較集中的劑被(bei)擠(ji)入絕緣層后形成(cheng)鼓包。

(2)保存不(bu)當(dang)的交聯聚乙烯(xi)(xi)絕緣(yuan)料，即使沒有使用催化劑(ji)，交聯聚乙烯(xi)(xi)料在(zai)室(shi)溫下也會(hui)慢慢交聯，這(zhe)是(shi)由(you)于材料中含有微(wei)量的水分(約(yue)50×10-4%)，在(zai)室(shi)溫下儲存，會(hui)造成擠出絕緣(yuan)層表面不(bu)光滑。
