日前，國網(wang)天(tian)津(jin)市電力(li)公司提出的“以電供熱(re)”試點規劃，被(bei)寫(xie)入天(tian)津(jin)市政(zheng)府(fu)工(gong)作(zuo)報(bao)告，預示(shi)著天(tian)津(jin)市加(jia)熱(re)電纜的需求量(liang)將不斷提高。“推廣(guang)電能替代(dai)工(gong)程，啟動以電供熱(re)試點”被(bei)寫(xie)入天(tian)津(jin)市政(zheng)府(fu)工(gong)作(zuo)報(bao)告，這標(biao)志著天(tian)津(jin)電能替代(dai)工(gong)作(zuo)已進入政(zheng)府(fu)主導、系統(tong)推進的新階段。

當前(qian)電能(neng)替代技術成(cheng)(cheng)熟，經濟優勢(shi)明顯，清潔環(huan)保已成(cheng)(cheng)為政府和廣大用戶的共識。一直以來，北(bei)方地區冬季供(gong)(gong)熱取暖主要是采用燃煤(mei)鍋爐，造成(cheng)(cheng)嚴重大氣(qi)污染。如(ru)果采取電能(neng)替代，以電能(neng)或(huo)太陽能(neng)代替燃煤(mei)蒸汽供(gong)(gong)熱，不但供(gong)(gong)熱成(cheng)(cheng)本大幅度降低，而且不會(hui)造成(cheng)(cheng)環(huan)境(jing)污染。

在有些(xie)專家看(kan)來(lai)，電(dian)能作為清潔能源的(de)優(you)勢凸顯，替(ti)代潛力巨大(da)。4月(yue)2日(ri)，國(guo)家電(dian)網公(gong)司召開了2015年電(dian)能替(ti)代工作推(tui)進會(hui)，發布了《國(guo)家電(dian)網公(gong)司2015年全(quan)面深(shen)入推(tui)進電(dian)能替(ti)代行動計(ji)劃》，提(ti)出了確保全(quan)年完成650億千(qian)瓦(wa)時(shi)、力爭實(shi)現750億千(qian)瓦(wa)時(shi)替(ti)代電(dian)量(liang)。

據了解(jie)，今年國家電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)網公(gong)司將著(zhu)力鞏固擴大(da)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)窯爐(lu)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)鍋爐(lu)、熱泵等成熟項目的實施(shi)范圍，因地(di)制(zhi)宜(yi)拓展新領域、推廣(guang)新技術，除(chu)在港口地(di)區推廣(guang)岸電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)替代(dai)(通過電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜將船舶用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)與岸上電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)連(lian)接，在船舶靠岸期間采用(yong)陸地(di)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian))外，還將對居民(min)區、學校(xiao)等用(yong)戶推廣(guang)碳(tan)晶、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)熱膜、發熱電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜等技術，在企(qi)事(shi)業(ye)單位(wei)食堂推廣(guang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁灶、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)蒸鍋，在油田推廣(guang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動鉆機(ji)，在油氣輸送管線推廣(guang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力加壓等。

從消(xiao)費端來看(kan)，各地主要通過以電(dian)(dian)代煤(mei)、以電(dian)(dian)代油來促進節能減排。北(bei)京市城六區基(ji)本取消(xiao)燃煤(mei)鍋爐(lu)，農村地區新增減煤(mei)換煤(mei)120萬噸。河(he)北(bei)省提出大幅壓(ya)減煤(mei)炭用量，實施(shi)煤(mei)電(dian)(dian)節能減排升(sheng)級改造行(xing)動計劃。在歐美(mei)發達國(guo)家，電(dian)(dian)采(cai)暖普(pu)及率非常高(gao)，美(mei)國(guo)80%的城市實行(xing)電(dian)(dian)采(cai)暖，加拿大、德國(guo)、法國(guo)等電(dian)(dian)采(cai)暖比例均在50%以上。

有專家分析(xi)認為，國內大力開展電(dian)(dian)能替代(dai)，能有效緩解電(dian)(dian)纜(lan)(lan)產(chan)業(ye)(ye)產(chan)能過剩帶來的巨大壓力。國內電(dian)(dian)線電(dian)(dian)纜(lan)(lan)行(xing)業(ye)(ye)產(chan)能過剩以及設備過剩是不(bu)(bu)爭的事(shi)實，產(chan)能過剩意(yi)味著供大于求，意(yi)味著惡性競爭;而(er)設備過剩又反映出開工(gong)(gong)率(lv)不(bu)(bu)足(zu)。事(shi)實上(shang)，僅(jin)次于汽車制造業(ye)(ye)的第二大產(chan)業(ye)(ye)電(dian)(dian)線電(dian)(dian)纜(lan)(lan)行(xing)業(ye)(ye)在(zai)贏得“全球第一”之(zhi)后，卻因蜂(feng)擁而(er)上(shang)深(shen)陷(xian)“紅海(hai)”的產(chan)能嚴重(zhong)過剩之(zhi)中。不(bu)(bu)足(zu)四成的產(chan)能開工(gong)(gong)率(lv)還不(bu)(bu)到歐(ou)美(mei)同期一半，連(lian)續萎(wei)靡的虧損包袱成為不(bu)(bu)少上(shang)市公(gong)司不(bu)(bu)能承受之(zhi)重(zhong)，欲剝離減負(fu)。

近來研發(fa)成功的(de)碳(tan)纖維加(jia)熱(re)電纜，將加(jia)熱(re)電纜系統(tong)的(de)應用推向了(le)技術(shu)創新階段(duan)。推行“以(yi)電供熱(re)”的(de)應用，廣泛涉及千家(jia)萬(wan)戶。例(li)如在住宅內部(bu)，可實(shi)現墻壁、地(di)板、空間加(jia)熱(re)。其中，僅墻壁和地(di)板加(jia)熱(re)系統(tong)，就(jiu)需要大量加(jia)熱(re)電纜。此外，根據外國經驗，道路和機場(chang)融(rong)雪(xue)加(jia)熱(re)，也普遍首選加(jia)熱(re)電纜系統(tong)。

電采暖相比(bi)燃煤采暖優勢比(bi)較明顯。當前，國(guo)(guo)內電力供需(xu)矛盾將日趨緩和，2006年中(zhong)國(guo)(guo)電力供需(xu)基(ji)本(ben)平(ping)衡。從2007年開始，一部分煤炭產地(di)為(wei)降低煤炭運(yun)輸(shu)(shu)成(cheng)本(ben)，大(da)力發(fa)(fa)展火力發(fa)(fa)電，變(bian)煤炭運(yun)輸(shu)(shu)為(wei)電力輸(shu)(shu)送，并且國(guo)(guo)家(jia)正在大(da)力發(fa)(fa)展風力發(fa)(fa)電、太陽能發(fa)(fa)電、水力發(fa)(fa)電、核電等，電力已出現(xian)冬季(ji)過(guo)剩(sheng)現(xian)象(xiang)，這就為(wei)電采暖提(ti)供了(le)足夠空間。

據相關(guan)統計數字表明，我國地面輻(fu)射采暖市場(chang)在2010年底(di)已達千億(yi)元，其中技術(shu)成熟的低溫熱水輻(fu)射采暖和散熱片采暖占(zhan)據70%以上的市場(chang)份(fen)(fen)額(e)。電采暖雖(sui)處于起步階(jie)段，但也(ye)占(zhan)據了25%左右的市場(chang)份(fen)(fen)額(e)，并且保持(chi)持(chi)續上升的趨勢。

如(ru)今，全國各(ge)地針對電(dian)(dian)采暖(nuan)(nuan)紛(fen)紛(fen)出(chu)臺優(you)惠政策，這從側面展(zhan)(zhan)現(xian)出(chu)了電(dian)(dian)采暖(nuan)(nuan)的(de)(de)巨大(da)潛力(li)，也為碳纖(xian)維發熱(re)電(dian)(dian)纜的(de)(de)發展(zhan)(zhan)提供(gong)了無(wu)限的(de)(de)可(ke)能性。就目前各(ge)個(ge)集中供(gong)暖(nuan)(nuan)區(qu)域推出(chu)的(de)(de)供(gong)暖(nuan)(nuan)政策來看，煤(mei)炭供(gong)熱(re)的(de)(de)時代正(zheng)在(zai)(zai)成為歷(li)史。而新型的(de)(de)環(huan)保節能的(de)(de)采暖(nuan)(nuan)方式正(zheng)在(zai)(zai)占領市(shi)場，其中電(dian)(dian)采暖(nuan)(nuan)以其成熟的(de)(de)行(xing)業體(ti)系(xi)和(he)卓越的(de)(de)供(gong)暖(nuan)(nuan)效果正(zheng)在(zai)(zai)不斷受到重視。這為正(zheng)處于產能過剩的(de)(de)電(dian)(dian)纜產業開辟了一個(ge)新的(de)(de)市(shi)場。
