產品詳細介紹：
倍容量復合材料(liao)芯(xin)鋁絞線(xian)(xian)JXRL/FH充分發揮了有(you)(you)機復合材料(liao)的(de)特長，與現有(you)(you)的(de)各種相比，具(ju)有(you)(you)強度高(gao)(gao)、線(xian)(xian)損低(di)、電導(dao)(dao)率高(gao)(gao)、弧垂(chui)小、允許(xu)工作溫度高(gao)(gao)、載流量大、重量輕、耐腐蝕及使用壽命長等優點，即使在(zai)導(dao)(dao)線(xian)(xian)載流量增加，導(dao)(dao)線(xian)(xian)溫度提高(gao)(gao)以后，導(dao)(dao)線(xian)(xian)的(de)運用仍是(shi)安(an)全(quan)可靠的(de)，從而實現了電力傳輸的(de)節(jie)能、環保(bao)與安(an)全(quan),其具(ju)體(ti)特點如下。

1.強度高
一般(ban)鋼絲的(de)(de)抗(kang)拉(la)(la)強(qiang)(qiang)度(du)為1240MPa,高強(qiang)(qiang)度(du)鋼絲為1410MPa,而倍容量(liang)復合(he)材(cai)料芯鋁絞JXRL/FH的(de)(de)碳(tan)纖維和玻(bo)璃纖維混(hun)合(he)固(gu)化芯棒，其抗(kang)拉(la)(la)強(qiang)(qiang)度(du)最小(xiao)值(zhi)可達(da)到2150MPa ,分別為前兩者的(de)(de)1.73倍和1.52倍。如芯線直徑為6.5MM的(de)(de)碳(tan)纖維和玻(bo)璃纖維混(hun)合(he)芯的(de)(de)抗(kang)拉(la)(la)強(qiang)(qiang)度(du)達(da)2500MPa,比一般(ban)鋼芯的(de)(de)抗(kang)拉(la)(la)強(qiang)(qiang)度(du)高一倍，比高強(qiang)(qiang)度(du)鋼芯的(de)(de)抗(kang)拉(la)(la)強(qiang)(qiang)度(du)高77%左(zuo)右。因倍容量(liang)復合(he)材(cai)料芯鋁絞線JXRL/FH的(de)(de)結(jie)構形式較為創新，因此有利用(yong)提(ti)高接(jie)續管(guan)、耐張線夾與導線的(de)(de)壓接(jie)強(qiang)(qiang)度(du)。

2.線損低、導電率高
由于倍(bei)容量復(fu)(fu)合(he)材(cai)料(liao)芯鋁(lv)絞(jiao)線(xian)(xian)(xian)JXRL/FH不存在鋼(gang)絲(si)材(cai)料(liao)引(yin)起(qi)的(de)(de)(de)磁滯損耗熱(re)效應，而且在輸(shu)送相(xiang)同負荷(he)的(de)(de)(de)條件(jian)下，具有更低的(de)(de)(de)運(yun)行溫(wen)度，可以減少輸(shu)電(dian)損失約(yue)6%左右。另外，倍(bei)容量復(fu)(fu)合(he)材(cai)料(liao)芯鋁(lv)絞(jiao)線(xian)(xian)(xian)JXRL/FH的(de)(de)(de)外層(ceng)由梯形截面軟(ruan)鋁(lv)形成的(de)(de)(de)外表(biao)(biao)面遠(yuan)比傳(chuan)統(tong)的(de)(de)(de)鋼(gang)芯鋁(lv)絞(jiao)線(xian)(xian)(xian)LGJ表(biao)(biao)面光滑，提(ti)高(gao)了導(dao)(dao)(dao)線(xian)(xian)(xian)表(biao)(biao)面粗糙系數，有利(li)于提(ti)高(gao)導(dao)(dao)(dao)線(xian)(xian)(xian)的(de)(de)(de)電(dian)暈(yun)起(qi)始電(dian)壓(ya)，減少電(dian)暈(yun)損失，降低電(dian)暈(yun)噪聲和無線(xian)(xian)(xian)電(dian)干(gan)擾水平。再者，由于外層(ceng)為梯形截面軟(ruan)鋁(lv)，與相(xiang)同直(zhi)徑(jing)的(de)(de)(de)鋼(gang)芯鋁(lv)絞(jiao)線(xian)(xian)(xian)LGJ相(xiang)比外層(ceng)纏繞的(de)(de)(de)導(dao)(dao)(dao)電(dian)鋁(lv)更多，提(ti)高(gao)了導(dao)(dao)(dao)線(xian)(xian)(xian)的(de)(de)(de)電(dian)導(dao)(dao)(dao)率。

3.弧垂小
碳纖維芯(xin)(xin)的(de)(de)線(xian)(xian)(xian)膨脹系數低(di)（1.6*10-6/℃），約為(wei)普通(tong)剛芯(xin)(xin)線(xian)(xian)(xian)膨脹系數（11.5*10-6/℃）的(de)(de)1/7，倍(bei)容量(liang)復(fu)合(he)(he)材(cai)(cai)料芯(xin)(xin)鋁(lv)絞(jiao)線(xian)(xian)(xian)JXRL/FH與常規(gui)導線(xian)(xian)(xian)相(xiang)比具有顯著的(de)(de)低(di)馳度特性(xing)。在(zai)相(xiang)同的(de)(de)實驗(yan)條(tiao)件(jian)下(xia)，溫度從26.1℃上升到183℃時，常規(gui)鋼芯(xin)(xin)鋁(lv)絞(jiao)線(xian)(xian)(xian)LGJ的(de)(de)弧(hu)垂(chui)(chui)(chui)236mm增(zeng)(zeng)加(jia)到1422mm，提(ti)高(gao)了(le)5倍(bei)，而倍(bei)容量(liang)復(fu)合(he)(he)材(cai)(cai)料芯(xin)(xin)鋁(lv)絞(jiao)線(xian)(xian)(xian)JXRL/FH的(de)(de)弧(hu)垂(chui)(chui)(chui)僅從198mm增(zeng)(zeng)加(jia)到312mm，提(ti)高(gao)僅0.58倍(bei)。倍(bei)容量(liang)復(fu)合(he)(he)材(cai)(cai)料芯(xin)(xin)鋁(lv)絞(jiao)線(xian)(xian)(xian)JXRL/FH弧(hu)垂(chui)(chui)(chui)的(de)(de)變(bian)化量(liang)僅為(wei)常規(gui)鋼芯(xin)(xin)鋁(lv)絞(jiao)線(xian)(xian)(xian)LGJ的(de)(de)9.6%，即在(zai)高(gao)溫條(tiao)件(jian)下(xia)，倍(bei)容量(liang)復(fu)合(he)(he)材(cai)(cai)料芯(xin)(xin)鋁(lv)絞(jiao)線(xian)(xian)(xian)JXRL/FH的(de)(de)弧(hu)垂(chui)(chui)(chui)變(bian)化量(liang)不到鋼芯(xin)(xin)鋁(lv)絞(jiao)線(xian)(xian)(xian)LGJ的(de)(de)1/10。由于倍(bei)容量(liang)復(fu)合(he)(he)材(cai)(cai)料芯(xin)(xin)鋁(lv)絞(jiao)線(xian)(xian)(xian)JXRL/FH在(zai)高(gao)溫條(tiao)件(jian)下(xia)的(de)(de)低(di)弧(hu)度特性(xing)，能有效減少架(jia)空線(xian)(xian)(xian)的(de)(de)空間走廊(lang)，提(ti)高(gao)導線(xian)(xian)(xian)高(gao)溫運(yun)行的(de)(de)安全性(xing)和(he)可靠性(xing)。

4.允許工作溫度高，載流量大
通(tong)過試驗研究發現，在(zai)相同(tong)(tong)的(de)(de)(de)(de)載(zai)(zai)流(liu)(liu)量(liang)(liang)時，倍(bei)容(rong)量(liang)(liang)復合(he)材(cai)料芯(xin)(xin)(xin)(xin)鋁(lv)(lv)(lv)(lv)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)(xian)(xian)(xian)JXRL/FH比鋼芯(xin)(xin)(xin)(xin)鋁(lv)(lv)(lv)(lv)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)(xian)(xian)(xian)LGJ溫度(du)低、弧(hu)垂小。由于(yu)(yu)弧(hu)垂很小，倍(bei)容(rong)量(liang)(liang)復合(he)材(cai)料芯(xin)(xin)(xin)(xin)鋁(lv)(lv)(lv)(lv)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)(xian)(xian)(xian)JXRL/FH可以承載(zai)(zai)更大(da)的(de)(de)(de)(de)電流(liu)(liu)；在(zai)相同(tong)(tong)的(de)(de)(de)(de)運行溫度(du)時，倍(bei)容(rong)量(liang)(liang)復合(he)材(cai)料芯(xin)(xin)(xin)(xin)鋁(lv)(lv)(lv)(lv)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)(xian)(xian)(xian)JXRL/FH的(de)(de)(de)(de)允(yun)(yun)(yun)許載(zai)(zai)流(liu)(liu)量(liang)(liang)比鋼芯(xin)(xin)(xin)(xin)鋁(lv)(lv)(lv)(lv)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)(xian)(xian)(xian)LGJ大(da)，在(zai)達到允(yun)(yun)(yun)許運行溫度(du)時，其允(yun)(yun)(yun)許載(zai)(zai)流(liu)(liu)量(liang)(liang)是鋼芯(xin)(xin)(xin)(xin)鋁(lv)(lv)(lv)(lv)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)(xian)(xian)(xian)LGJ的(de)(de)(de)(de)2倍(bei)；在(zai)相同(tong)(tong)外(wai)徑時，倍(bei)容(rong)量(liang)(liang)復合(he)材(cai)料芯(xin)(xin)(xin)(xin)鋁(lv)(lv)(lv)(lv)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)(xian)(xian)(xian)JXRL/FH外(wai)層允(yun)(yun)(yun)許纏繞超過29%的(de)(de)(de)(de)導電鋁(lv)(lv)(lv)(lv)線(xian)(xian)(xian)(xian)(xian)，即倍(bei)容(rong)量(liang)(liang)復合(he)材(cai)料芯(xin)(xin)(xin)(xin)鋁(lv)(lv)(lv)(lv)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)(xian)(xian)(xian)JXRL/FH的(de)(de)(de)(de)鋁(lv)(lv)(lv)(lv)材(cai)截面為常規鋼芯(xin)(xin)(xin)(xin)鋁(lv)(lv)(lv)(lv)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)(xian)(xian)(xian)LGJ的(de)(de)(de)(de)1.29倍(bei)，由于(yu)(yu)增加了導電面積，可提高(gao)載(zai)(zai)流(liu)(liu)量(liang)(liang)29%；在(zai)相同(tong)(tong)的(de)(de)(de)(de)鋁(lv)(lv)(lv)(lv)截面時，倍(bei)容(rong)量(liang)(liang)復合(he)材(cai)料芯(xin)(xin)(xin)(xin)鋁(lv)(lv)(lv)(lv)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)(xian)(xian)(xian)JXRL/FH的(de)(de)(de)(de)成品重量(liang)(liang)與常規的(de)(de)(de)(de)鋼芯(xin)(xin)(xin)(xin)鋁(lv)(lv)(lv)(lv)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)(xian)(xian)(xian)LGJ相比輕10%-15%，因(yin)此，能夠利用現有路線(xian)(xian)(xian)(xian)(xian)結構替(ti)換(huan)導線(xian)(xian)(xian)(xian)(xian)達到增容(rong)目的(de)(de)(de)(de)。

5.重量輕
碳纖維(wei)復合(he)(he)(he)(he)芯材(cai)料(liao)(liao)的(de)(de)(de)密(mi)度(du)(du)小(xiao)（1.8g/m3），約(yue)為(wei)(wei)普通(tong)鋼(gang)(gang)芯密(mi)度(du)(du)（7.78g/m3）的(de)(de)(de)1/4。倍(bei)(bei)容(rong)(rong)(rong)(rong)量(liang)(liang)復合(he)(he)(he)(he)材(cai)料(liao)(liao)芯鋁(lv)(lv)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)(xian)JXRL/FH單(dan)位長度(du)(du)約(yue)為(wei)(wei)常(chang)規鋼(gang)(gang)芯鋁(lv)(lv)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)(xian)LGJ的(de)(de)(de)60%-80%，如(ru)常(chang)規鋼(gang)(gang)芯鋁(lv)(lv)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)(xian)LGJ（240/55）單(dan)位長度(du)(du)重(zhong)量(liang)(liang)為(wei)(wei)1.09kg/m（其(qi)中鋁(lv)(lv)材(cai)部分為(wei)(wei)0.651kg/m,鋼(gang)(gang)芯部分為(wei)(wei)0.439kg/m）,而倍(bei)(bei)容(rong)(rong)(rong)(rong)量(liang)(liang)復合(he)(he)(he)(he)材(cai)料(liao)(liao)芯鋁(lv)(lv)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)(xian)JXRL/FH（218/28）為(wei)(wei)0.655kg/m(其(qi)中復合(he)(he)(he)(he)材(cai)料(liao)(liao)芯僅0.052kg/m),顯(xian)示了倍(bei)(bei)容(rong)(rong)(rong)(rong)量(liang)(liang)復合(he)(he)(he)(he)材(cai)料(liao)(liao)芯鋁(lv)(lv)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)(xian)JXRL/FH重(zhong)量(liang)(liang)輕的(de)(de)(de)優(you)點。計(ji)算表明由于導線(xian)(xian)(xian)自重(zhong)的(de)(de)(de)減輕使(shi)桿(gan)塔(ta)(ta)載荷減輕25%，因(yin)此，桿(gan)塔(ta)(ta)承載能力增(zeng)加20%；導線(xian)(xian)(xian)重(zhong)量(liang)(liang)減輕后可使(shi)桿(gan)塔(ta)(ta)高度(du)(du)降(jiang)低，同時可使(shi)桿(gan)塔(ta)(ta)結(jie)構更趨(qu)緊湊，縮小(xiao)基礎根開。縮短施(shi)工(gong)工(gong)期(qi)，節(jie)省線(xian)(xian)(xian)路綜合(he)(he)(he)(he)造價。倍(bei)(bei)容(rong)(rong)(rong)(rong)量(liang)(liang)復合(he)(he)(he)(he)材(cai)料(liao)(liao)芯鋁(lv)(lv)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)(xian)JXRL/FH的(de)(de)(de)滑輪通(tong)過試驗表明，倍(bei)(bei)容(rong)(rong)(rong)(rong)量(liang)(liang)復合(he)(he)(he)(he)材(cai)料(liao)(liao)芯鋁(lv)(lv)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)(xian)JXRL/FH架線(xian)(xian)(xian)施(shi)工(gong)可以使(shi)用常(chang)規鋼(gang)(gang)芯鋁(lv)(lv)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)(xian)LGJ用的(de)(de)(de)放線(xian)(xian)(xian)滑輪。

6.耐腐蝕、使用壽命長
由于復合芯棒外表面包覆的(de)(de)是絕緣體的(de)(de)玻璃纖維(wei)層，芯棒與鋁股之(zhi)間不存在(zai)接觸電(dian)(dian)位差，避免了(le)諸如(ru)鋼芯鋁絞(jiao)線(xian)(xian)LGJ的(de)(de)導體在(zai)通電(dian)(dian)時鋁線(xian)(xian)與鍍(du)鋅鋼線(xian)(xian)之(zhi)間的(de)(de)電(dian)(dian)化(hua)腐蝕問(wen)題，能保護(hu)鋁導體免受電(dian)(dian)腐蝕，同時該導線(xian)(xian)屬于自阻(zu)尼結構，具(ju)有(you)(you)優越的(de)(de)防(fang)振性。因此，有(you)(you)效地延(yan)緩了(le)導線(xian)(xian)的(de)(de)老化(hua)，延(yan)長了(le)導線(xian)(xian)的(de)(de)使用壽命。
