光伏耐火花線廠家電(dian)纜(lan)(lan)時常(chang)暴露(lu)在(zai)(zai)陽(yang)光之下，太(tai)陽(yang)能(neng)(neng)系(xi)(xi)統(tong)(tong)常(chang)常(chang)會在(zai)(zai)惡(e)劣(lie)環境條件下使用(yong)(yong)(yong)，如高(gao)溫和(he)紫外線(xian)輻射。在(zai)(zai)歐(ou)洲,晴天時將導(dao)致太(tai)陽(yang)能(neng)(neng)系(xi)(xi)統(tong)(tong)的(de)(de)現場溫度(du)(du)高(gao)達100°C。目前(qian),我們可采(cai)用(yong)(yong)(yong)的(de)(de)各(ge)種材料有PVC、橡膠(jiao)、TPE和(he)高(gao)質量交叉(cha)鏈(lian)接(jie)材料，但遺憾的(de)(de)是(shi)，額(e)定(ding)溫度(du)(du)為(wei)90°C的(de)(de)橡膠(jiao)電(dian)纜(lan)(lan)，還有即便是(shi)額(e)定(ding)溫度(du)(du)為(wei)70°C的(de)(de)PVC電(dian)纜(lan)(lan)也常(chang)常(chang)在(zai)(zai)戶(hu)外使用(yong)(yong)(yong)，，目前(qian)國家金太(tai)陽(yang)工程頻頻上馬，有許多(duo)承建商為(wei)了節省成本，不選擇(ze)太(tai)陽(yang)能(neng)(neng)系(xi)(xi)統(tong)(tong)專用(yong)(yong)(yong)電(dian)纜(lan)(lan)，而是(shi)選擇(ze)普通的(de)(de)pvc電(dian)纜(lan)(lan)來替代光伏(fu)電(dian)纜(lan)(lan)，顯然,這(zhe)將大(da)大(da)影響系(xi)(xi)統(tong)(tong)的(de)(de)使用(yong)(yong)(yong)壽命。

1. 看電纜電線長度：上海阻燃的耐火花線國家標準規定，電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜每(mei)卷100米(mi)，計量(liang)誤差不大于0.5%，也(ye)就(jiu)是每(mei)卷線(xian)(xian)的(de)(de)(de)(de)長度為100±0.5米(mi)，但是有些商家標注(zhu)的(de)(de)(de)(de)是100±20米(mi)，但實(shi)際上，卻只有80米(mi)左右。2. 看電(dian)(dian)(dian)阻值：電(dian)(dian)(dian)阻值超標的(de)(de)(de)(de)話，電(dian)(dian)(dian)線(xian)(xian)就(jiu)容(rong)(rong)易(yi)(yi)(yi)出現溫度過高、老化(hua)的(de)(de)(de)(de)危險(xian)，而且如(ru)果電(dian)(dian)(dian)線(xian)(xian)短路(lu)的(de)(de)(de)(de)話，還(huan)會引發火(huo)災(zai)。并且電(dian)(dian)(dian)阻值超標，還(huan)增加傳輸電(dian)(dian)(dian)量(liang)時的(de)(de)(de)(de)消耗，增加電(dian)(dian)(dian)費，所以，我們在選擇時，一定要(yao)留意這一點。3.看原材(cai)料：純銅芯的(de)(de)(de)(de)材(cai)料導(dao)電(dian)(dian)(dian)性好(hao)，而且不易(yi)(yi)(yi)老化(hua)，更加耐用(yong)(yong)，也(ye)減少(shao)了故障發生。但是有些商家，會在銅材(cai)質中添加一些雜(za)質銅、回(hui)收銅，還(huan)有的(de)(de)(de)(de)劣質產品通過降低銅芯實(shi)際截面積，來減少(shao)銅材(cai)質的(de)(de)(de)(de)用(yong)(yong)量(liang)，這樣(yang)容(rong)(rong)易(yi)(yi)(yi)導(dao)致電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜用(yong)(yong)電(dian)(dian)(dian)過程(cheng)中發熱，損壞(huai)外邊的(de)(de)(de)(de)絕緣層塑料，容(rong)(rong)易(yi)(yi)(yi)讓電(dian)(dian)(dian)線(xian)(xian)老化(hua)，導(dao)致出現漏(lou)電(dian)(dian)(dian)、短路(lu)的(de)(de)(de)(de)問題。

耐火花線RVS電線(xian)全稱：銅芯聚氯乙烯絕緣絞型連接用(yong)軟電線(xian)、對絞多股(gu)軟線(xian)，簡稱雙絞線(xian)，俗稱“花線(xian)”，現階段此種線(xian)材多用(yong)于消(xiao)防系統，也(ye)叫“消(xiao)防線(xian)”。

3月24日，阻燃的耐火花線廠家國(guo)家(jia)電網(wang)有(you)限公司(si)發布(bu)了(le)《國(guo)家(jia)電網(wang)有(you)限公司(si)2019社(she)會責任報告》。承諾(nuo)2020年(nian)將(jiang)實現利潤810億(yi)元(yuan)(yuan)，營(ying)(ying)(ying)收(shou)2.76萬億(yi)元(yuan)(yuan)。報告顯(xian)示(shi)，2019年(nian)，國(guo)家(jia)電網(wang)實現利潤總額770.3億(yi)元(yuan)(yuan)，營(ying)(ying)(ying)收(shou)26604.3億(yi)元(yuan)(yuan)，實現利稅1685.2億(yi)元(yuan)(yuan)。同(tong)時，國(guo)家(jia)電網(wang)對(dui)2020年(nian)經濟效(xiao)益(yi)承諾(nuo)，2020年(nian)將(jiang)實現利潤810億(yi)元(yuan)(yuan)，營(ying)(ying)(ying)收(shou)2.76萬億(yi)元(yuan)(yuan)，發展總投(tou)入4973億(yi)元(yuan)(yuan)，其中電網(wang)投(tou)資(zi)4080億(yi)元(yuan)(yuan)（受大規模重啟的特高壓工(gong)程拉動，國(guo)家(jia)電網(wang)今年(nian)的電網(wang)投(tou)資(zi)計劃已升至4500億(yi)元(yuan)(yuan)，增(zeng)幅(fu)逾10%）。同(tong)時提出，做好新能(neng)源并(bing)網(wang)服務和消(xiao)納(na)，確保(bao)風電、光伏發電利用率均達到95%以上(shang)。

上海阻燃的耐火花線廠家復(fu)工復(fu)產(chan)順利(li)推(tui)進 3月(yue)份發(fa)(fa)用電(dian)(dian)(dian)量(liang)回升明顯，從發(fa)(fa)電(dian)(dian)(dian)看，今年(nian)前2個月(yue)全國規模以上工業發(fa)(fa)電(dian)(dian)(dian)量(liang)同(tong)比(bi)下(xia)降(jiang)8.2%。其中，火電(dian)(dian)(dian)、水電(dian)(dian)(dian)、核電(dian)(dian)(dian)、風電(dian)(dian)(dian)發(fa)(fa)電(dian)(dian)(dian)同(tong)比(bi)分別下(xia)降(jiang)8.9%、11.9%、2.2%、0.2%，太(tai)陽(yang)能發(fa)(fa)電(dian)(dian)(dian)同(tong)比(bi)增長(chang)12.0%。
