近日，重慶市能源局、性價比低壓無鹵電線國網(wang)重(zhong)慶市(shi)(shi)電(dian)(dian)力公(gong)司處消息稱(cheng)，白(bai)鶴(he)灘-江(jiang)蘇±800kV特(te)高(gao)壓(ya)(ya)直(zhi)流(liu)(liu)輸(shu)(shu)(shu)電(dian)(dian)工程即將開建(jian)。該線(xian)路綜合航空直(zhi)線(xian)長度1783公(gong)里，途經(jing)四川、重(zhong)慶、湖(hu)北(bei)、安徽(hui)、江(jiang)蘇五省(sheng)(sheng)份。據介紹(shao)，白(bai)鶴(he)灘-江(jiang)蘇±800kV特(te)高(gao)壓(ya)(ya)直(zhi)流(liu)(liu)輸(shu)(shu)(shu)電(dian)(dian)工程起于四川省(sheng)(sheng)涼山州的(de)布拖(tuo)換流(liu)(liu)站(zhan)（先鋒站(zhan)址(zhi)），止于江(jiang)蘇省(sheng)(sheng)蘇州市(shi)(shi)的(de)虞(yu)山換流(liu)(liu)站(zhan)（羅家浜站(zhan)址(zhi)），輸(shu)(shu)(shu)送(song)容量(liang)800萬(wan)千瓦，送(song)電(dian)(dian)距離約(yue)2172公(gong)里。該特(te)高(gao)壓(ya)(ya)直(zhi)流(liu)(liu)輸(shu)(shu)(shu)電(dian)(dian)工程重(zhong)慶段依次途經(jing)永川、江(jiang)津、綦江(jiang)、巴南、南川、武隆(long)、彭水和(he)黔(qian)江(jiang)8個區縣，線(xian)路長度約(yue)329公(gong)里，目(mu)前重(zhong)慶段已取齊了(le)核準要件，完成了(le)設計終堪定位工作，預計將于今(jin)年6月開工。

性價比低壓無鹵電線批發電(dian)(dian)線電(dian)(dian)纜(lan)(lan)的(de)(de)(de)制造與大多(duo)數機(ji)電(dian)(dian)產(chan)品(pin)(pin)的(de)(de)(de)生(sheng)產(chan)方式(shi)是(shi)(shi)完全不(bu)同的(de)(de)(de)。機(ji)電(dian)(dian)產(chan)品(pin)(pin)通(tong)常采用將另(ling)(ling)件(jian)裝(zhuang)配成(cheng)(cheng)部(bu)件(jian)、多(duo)個部(bu)件(jian)再裝(zhuang)配成(cheng)(cheng)單(dan)臺產(chan)品(pin)(pin)，產(chan)品(pin)(pin)以臺數或(huo)件(jian)數計量(liang)(liang)。電(dian)(dian)線電(dian)(dian)纜(lan)(lan)是(shi)(shi)以長(chang)度為基本計量(liang)(liang)單(dan)位。所有電(dian)(dian)線電(dian)(dian)纜(lan)(lan)都是(shi)(shi)從導體(ti)(ti)加工開(kai)始，在導體(ti)(ti)的(de)(de)(de)外圍一層一層地(di)加上絕(jue)緣、屏蔽(bi)、、成(cheng)(cheng)纜(lan)(lan)、護層等而制成(cheng)(cheng)電(dian)(dian)線電(dian)(dian)纜(lan)(lan)產(chan)品(pin)(pin)。產(chan)品(pin)(pin)結構越復雜(za)，疊加的(de)(de)(de)層次就(jiu)越多(duo)。大長(chang)度連(lian)續疊加組(zu)合的(de)(de)(de)生(sheng)產(chan)方式(shi)，使生(sheng)產(chan)過(guo)程中任(ren)何一個環節、瞬(shun)時發生(sheng)一點問題，就(jiu)會(hui)影響整根電(dian)(dian)纜(lan)(lan)質量(liang)(liang)。質量(liang)(liang)缺陷(xian)越是(shi)(shi)發生(sheng)在內(nei)層，而且沒有及時發現終止生(sheng)產(chan)，那(nei)么造成(cheng)(cheng)的(de)(de)(de)損失就(jiu)越大。因為電(dian)(dian)線電(dian)(dian)纜(lan)(lan)的(de)(de)(de)生(sheng)產(chan)不(bu)同于組(zu)裝(zhuang)式(shi)的(de)(de)(de)產(chan)品(pin)(pin)，可以拆開(kai)重裝(zhuang)及更換另(ling)(ling)件(jian)；電(dian)(dian)線電(dian)(dian)纜(lan)(lan)的(de)(de)(de)任(ren)一部(bu)件(jian)或(huo)工藝過(guo)程的(de)(de)(de)質量(liang)(liang)問題，對這根電(dian)(dian)纜(lan)(lan)幾(ji)乎是(shi)(shi)無法挽回(hui)和彌補的(de)(de)(de)。事(shi)后的(de)(de)(de)處理都是(shi)(shi)十分消極(ji)的(de)(de)(de)，不(bu)是(shi)(shi)鋸(ju)短(duan)就(jiu)是(shi)(shi)降級處理，要么報廢整條電(dian)(dian)纜(lan)(lan)。它(ta)無法拆開(kai)重裝(zhuang)。

印度總理莫迪當地時間3日就新冠肺炎疫情發表全國電視講話，呼吁民眾在4月5日晚上9點熄燈9分鐘，以“燭光”祈福團結抗疫。然而，該建議隨后在該國引發巨大爭議，馬哈拉施特拉邦能源部長尼廷·勞特就警告說，這一措施可能導致低壓無鹵電線電網崩(beng)潰，意味(wei)著應急服務也(ye)將受到(dao)影響。對(dui)此，據《印度斯坦時(shi)報》報道，印度電力(li)部(bu)澄清：總理的熄燈呼吁只針對(dui)普通住(zhu)宅，不(bu)會影響電網系統(tong)。

1.紫外線(UV)——不要將無紫外線防護的低壓無鹵電線電(dian)纜(lan)(lan)(lan)(lan)應(ying)用(yong)于陽光(guang)的(de)直(zhi)射環(huan)境內。2.熱度(du)——電(dian)纜(lan)(lan)(lan)(lan)在金(jin)屬管道或(huo)(huo)線槽(cao)內的(de)溫度(du)很(hen)高,許多聚(ju)合材料在這種溫度(du)下會降低使用(yong)壽命。3.水(shui)——在局域(yu)網(wang)雙絞(jiao)(jiao)線電(dian)纜(lan)(lan)(lan)(lan)的(de)水(shui)分(fen)會增(zeng)加電(dian)纜(lan)(lan)(lan)(lan)的(de)電(dian)容(rong),從而降低了阻抗并引起近端(duan)(duan)串擾(rao)問題(ti)。4.機(ji)械損壞(huai)(修復費用(yong))——光(guang)纜(lan)(lan)(lan)(lan)的(de)修復是十(shi)分(fen)昂貴的(de)，在每(mei)一(yi)個間(jian)斷點至(zhi)少需要(yao)兩次端(duan)(duan)接(jie)(jie)。5.接(jie)(jie)地——如(ru)果電(dian)纜(lan)(lan)(lan)(lan)的(de)屏蔽層需要(yao)接(jie)(jie)地,則(ze)必須遵(zun)守相(xiang)應(ying)的(de)標準。6.路由(you)總長度(du)(不(bu)僅僅指樓間(jian))——大(da)樓間(jian)采用(yong)室(shi)外級(ji)的(de)局域(yu)網(wang)雙絞(jiao)(jiao)線電(dian)纜(lan)(lan)(lan)(lan),其總長度(du)要(yao)限(xian)制在90米之(zhi)內。對于100Mps或(huo)(huo)1000Mbps網(wang)絡，其鋪設距離(li)不(bu)能超過(guo)這一(yi)限(xian)度(du)。如(ru)鋪設的(de)距離(li)在100米到300米之(zhi)間(jian)，則(ze)應(ying)該選擇光(guang)纜(lan)(lan)(lan)(lan)。
