目前，南方耐火花線電(dian)網(wang)(wang)正(zheng)加快推進特(te)(te)(te)高(gao)(gao)壓(ya)等(deng)新型基(ji)礎設施項目建(jian)設。在南(nan)方電(dian)網(wang)(wang)重點特(te)(te)(te)高(gao)(gao)壓(ya)工(gong)(gong)程(cheng)——昆(kun)柳龍直(zhi)流(liu)輸電(dian)工(gong)(gong)程(cheng)建(jian)設方面，南(nan)網(wang)(wang)科研(yan)(yan)院科研(yan)(yan)工(gong)(gong)作者已連(lian)續攻克了(le)特(te)(te)(te)高(gao)(gao)電(dian)壓(ya)、特(te)(te)(te)大(da)電(dian)流(liu)下的絕緣特(te)(te)(te)性、電(dian)磁環境、設備(bei)研(yan)(yan)制(zhi)、試驗(yan)技術等(deng)世界級難題(ti)。有力(li)推動了(le)這個世界首個特(te)(te)(te)高(gao)(gao)壓(ya)多端混合直(zhi)流(liu)工(gong)(gong)程(cheng)、國家特(te)(te)(te)高(gao)(gao)壓(ya)多端直(zhi)流(liu)示范工(gong)(gong)程(cheng)的建(jian)設進度(du)。

首先可以看到質量達標的環保電線電纜產品能夠在多種環境下使用，其用到的材料和技術工藝能夠讓這些電纜在惡劣的環境當中保持足夠的穩定性，更重要的是這些環保耐火花線電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)抗(kang)(kang)腐蝕(shi)、抗(kang)(kang)電(dian)(dian)(dian)(dian)(dian)磁(ci)干擾(rao)的(de)能力也非常令人滿(man)意(yi)。進一步(bu)來(lai)(lai)(lai)講，備受青(qing)睞(lai)的(de)環(huan)保(bao)(bao)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)材料(liao)(liao)擁有非常好(hao)的(de)耐用性(xing)特點，產品扎實的(de)材料(liao)(liao)和技術(shu)工(gong)藝(yi)讓(rang)(rang)它充分達到了很(hen)多關(guan)鍵性(xing)電(dian)(dian)(dian)(dian)(dian)力產業的(de)耐用性(xing)標準，極強的(de)抗(kang)(kang)老化、抗(kang)(kang)氧化能力讓(rang)(rang)它可以(yi)成(cheng)為當前電(dian)(dian)(dian)(dian)(dian)力產業當中不可或缺的(de)組成(cheng)部分。另外從施(shi)工(gong)角度可以(yi)看出來(lai)(lai)(lai)好(hao)的(de)環(huan)保(bao)(bao)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)材料(liao)(liao)施(shi)工(gong)方法比較便捷，也就(jiu)是(shi)說這些電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)能夠以(yi)當下比較成(cheng)熟(shu)的(de)施(shi)工(gong)方法進行鋪(pu)設和安(an)裝，對于(yu)提升(sheng)電(dian)(dian)(dian)(dian)(dian)力設施(shi)安(an)裝施(shi)工(gong)效率和性(xing)價比來(lai)(lai)(lai)說是(shi)十分讓(rang)(rang)人滿(man)意(yi)的(de)。值得(de)一提的(de)是(shi)靠(kao)譜(pu)的(de)技術(shu)支(zhi)持(chi)也是(shi)這些環(huan)保(bao)(bao)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)品牌讓(rang)(rang)人感到可靠(kao)的(de)關(guan)鍵。

性價比耐火花線電(dian)(dian)線(xian)(xian)(xian)使(shi)用(yong)期限(xian)的(de)(de)長短，取決于(yu)電(dian)(dian)線(xian)(xian)(xian)的(de)(de)質量(liang)和電(dian)(dian)線(xian)(xian)(xian)安(an)裝的(de)(de)環(huan)(huan)境、使(shi)用(yong)環(huan)(huan)境。電(dian)(dian)線(xian)(xian)(xian)主要靠外(wai)面一層包皮絕(jue)緣(yuan)，時(shi)間一長，受到(dao)腐蝕性(xing)(xing)氣體(ti)的(de)(de)腐蝕，絕(jue)緣(yuan)性(xing)(xing)能(neng)逐漸降低，慢(man)慢(man)老化變硬，發脆或脫落，這時(shi)就不起(qi)絕(jue)緣(yuan)作用(yong)了(le)。家用(yong)電(dian)(dian)線(xian)(xian)(xian)的(de)(de)外(wai)表的(de)(de)絕(jue)緣(yuan)層多用(yong)塑料(liao)和橡(xiang)膠制成，使(shi)用(yong)時(shi)間長了(le)就會老化，失去(qu)絕(jue)緣(yuan)作用(yong)。電(dian)(dian)線(xian)(xian)(xian)失去(qu)絕(jue)緣(yuan)的(de)(de)性(xing)(xing)能(neng)是很危險的(de)(de)，如(ru)果兩根(gen)電(dian)(dian)線(xian)(xian)(xian)碰在一起(qi)或火線(xian)(xian)(xian)碰到(dao)與(yu)大地相(xiang)接(jie)的(de)(de)東西，就會發生跑電(dian)(dian)現象，使(shi)局部電(dian)(dian)線(xian)(xian)(xian)的(de)(de)溫度升高，產生火花。如(ru)果電(dian)(dian)線(xian)(xian)(xian)附近有易燃物就容易引起(qi)著火，造成火災(zai)。

性價比耐火花線電纜老(lao)化原因：外力的(de)(de)(de)(de)(de)損傷。由近幾(ji)年的(de)(de)(de)(de)(de)數據(ju)分(fen)析來看，尤其是(shi)在(zai)經濟(ji)高速發展中的(de)(de)(de)(de)(de)上海，現在(zai)的(de)(de)(de)(de)(de)大多(duo)數電纜故障都是(shi)因為機械損傷引起(qi)的(de)(de)(de)(de)(de)。譬如：電纜在(zai)敷設安裝的(de)(de)(de)(de)(de)過程中不按照(zhao)正常規范施工(gong)，容易(yi)造(zao)成機械損傷；在(zai)直(zhi)埋電纜上建造(zao)施工(gong)也特別(bie)容易(yi)將運行中的(de)(de)(de)(de)(de)電纜損傷等。有時如果損傷不嚴重(zhong)，要(yao)經過數年才會導致(zhi)損傷部位徹底擊穿(chuan)形(xing)成故障，有時破壞相對比較嚴重(zhong)的(de)(de)(de)(de)(de)可能(neng)會發生(sheng)短路故障，直(zhi)接影響(xiang)到用電單位的(de)(de)(de)(de)(de)安全。
