一、電纜支架在深圳市場行情怎么樣？

深圳電(dian)(dian)纜(lan)(lan)支(zhi)架在深圳的(de)(de)各類變(bian)(bian)電(dian)(dian)站應(ying)用(yong)(yong)：35KV、110KV、220KV、330KV、500KV變(bian)(bian)電(dian)(dian)站進出(chu)線的(de)(de)電(dian)(dian)纜(lan)(lan)溝,變(bian)(bian)電(dian)(dian)站內(nei)(nei)部的(de)(de)電(dian)(dian)纜(lan)(lan)夾層等支(zhi)架用(yong)(yong)量也(ye)非常大隧(sui)道(dao)(dao)應(ying)用(yong)(yong)：地(di)鐵、鐵路(lu)隧(sui)道(dao)(dao)、公路(lu)隧(sui)道(dao)(dao)、過(guo)江隧(sui)道(dao)(dao)、山體隧(sui)道(dao)(dao)等使用(yong)(yong)。現(xian)在全國(guo)有(you)(you)北京、上(shang)海、杭(hang)州、廣(guang)州、深圳、沈陽(yang)、西安、等十幾個(ge)城(cheng)市在上(shang)地(di)鐵項目，地(di)鐵具有(you)(you)強大的(de)(de)市場(chang)潛力。  發電(dian)(dian)設施(shi)應(ying)用(yong)(yong)：水(shui)電(dian)(dian)站、核電(dian)(dian)站、熱電(dian)(dian)廠等也(ye)要(yao)用(yong)(yong)到(dao)電(dian)(dian)纜(lan)(lan)支(zhi)架，國(guo)家每年(nian)新增裝機容(rong)量達到(dao)7000MVA，而且許多(duo)核電(dian)(dian)站已經批準(zhun)開工(gong)建(jian)(jian)設，所以這一塊市場(chang)也(ye)很大。  現(xian)代城(cheng)市建(jian)(jian)設的(de)(de)腳步在不斷的(de)(de)加(jia)快，為(wei)了滿(man)足要(yao)求，電(dian)(dian)纜(lan)(lan)的(de)(de)發展(zhan)也(ye)在飛(fei)速的(de)(de)發展(zhan)著(zhu)。電(dian)(dian)纜(lan)(lan)支(zhi)架成(cheng)為(wei)發展(zhan)的(de)(de)必需品，采用(yong)(yong)專(zhuan)業(ye)的(de)(de)技術、高品質的(de)(de)材(cai)料生(sheng)產了多(duo)樣化(hua)的(de)(de)產品，玻璃鋼電(dian)(dian)纜(lan)(lan)支(zhi)架具有(you)(you)安裝簡便，抗老化(hua)、綠(lv)色環(huan)保的(de)(de)優點，在電(dian)(dian)纜(lan)(lan)行(xing)業(ye)內(nei)(nei)具有(you)(you)較好的(de)(de)口(kou)碑(bei)。因此(ci)，組合式電(dian)(dian)纜(lan)(lan)支(zhi)架被應(ying)用(yong)(yong)在多(duo)個(ge)行(xing)業(ye)內(nei)(nei)。

二、深圳玻璃鋼電纜支架能否替代金屬支架            

隨著電力技術(shu)的發(fa)展(zhan)要求和(he)高分子復(fu)合(he)材料(liao)的進步，國家對低(di)碳減排政(zheng)策逐漸明(ming)朗，在我國用玻璃鋼電纜支(zhi)架替代角鋼支(zhi)架也是形(xing)勢所趨(qu)！

1、目前角鋼支(zhi)(zhi)(zhi)架(jia)(jia)(jia)存在問(wen)題長(chang)期以來，架(jia)(jia)(jia)設公用(yong)(yong)(yong)(yong)(yong)(yong)事業和(he)(he)工(gong)(gong)(gong)業電纜(lan)均采(cai)用(yong)(yong)(yong)(yong)(yong)(yong)金(jin)(jin)(jin)(jin)屬(shu)制(zhi)電纜(lan)支(zhi)(zhi)(zhi)架(jia)(jia)(jia)。金(jin)(jin)(jin)(jin)屬(shu)支(zhi)(zhi)(zhi)架(jia)(jia)(jia)通常(chang)是把(ba)鋼材(cai)或(huo)鋁合(he)金(jin)(jin)(jin)(jin)材(cai)軋制(zhi)成(cheng)(cheng)所需型材(cai)后，經(jing)焊接或(huo)用(yong)(yong)(yong)(yong)(yong)(yong)緊固件拼裝而成(cheng)(cheng)。傳統金(jin)(jin)(jin)(jin)屬(shu)支(zhi)(zhi)(zhi)架(jia)(jia)(jia)生產過(guo)程(cheng)(cheng)能耗大(da)、工(gong)(gong)(gong)序(xu)多(duo)(duo)、周期長(chang)。在許多(duo)(duo)惡劣環(huan)境(jing)條件下，例如地鐵、隧(sui)道、化工(gong)(gong)(gong)企(qi)業、多(duo)(duo)雨潮濕或(huo)沿海(hai)鹽霧(wu)等場(chang)(chang)(chang)合(he)，使用(yong)(yong)(yong)(yong)(yong)(yong)金(jin)(jin)(jin)(jin)屬(shu)支(zhi)(zhi)(zhi)架(jia)(jia)(jia)極易銹蝕(shi)(shi)，設施(shi)(shi)的(de)維護費用(yong)(yong)(yong)(yong)(yong)(yong)高(gao)，使用(yong)(yong)(yong)(yong)(yong)(yong)壽命也(ye)較短。在防銹防腐方面，目前雖(sui)采(cai)用(yong)(yong)(yong)(yong)(yong)(yong)外涂油(you)漆或(huo)熱浸鋅等技術處理(li)，但仍不能從(cong)根本上解(jie)決(jue)銹蝕(shi)(shi)問(wen)題，影響電力、通信設施(shi)(shi)的(de)安全和(he)(he)無故障使用(yong)(yong)(yong)(yong)(yong)(yong)期。此外，電纜(lan)架(jia)(jia)(jia)設使用(yong)(yong)(yong)(yong)(yong)(yong)金(jin)(jin)(jin)(jin)屬(shu)支(zhi)(zhi)(zhi)架(jia)(jia)(jia)時，電流流經(jing)電纜(lan)過(guo)程(cheng)(cheng)會產生磁(ci)場(chang)(chang)(chang)，導致兩(liang)個支(zhi)(zhi)(zhi)架(jia)(jia)(jia)角鋼之間形成(cheng)(cheng)磁(ci)場(chang)(chang)(chang)閉合(he)回(hui)路(環(huan)流)，使電纜(lan)溫度(du)升(sheng)(sheng)高(gao)，電流損(sun)失加(jia)大(da)，并進(jin)一步使環(huan)流溫度(du)升(sheng)(sheng)高(gao)。尤其當電纜(lan)通過(guo)大(da)電流時，溫度(du)迅速(su)升(sheng)(sheng)高(gao)，往往會形成(cheng)(cheng)強大(da)的(de)弧光而損(sun)毀金(jin)(jin)(jin)(jin)屬(shu)支(zhi)(zhi)(zhi)架(jia)(jia)(jia)。為了輸(shu)電安全，目前主(zhu)要(yao)(yao)(yao)采(cai)取加(jia)粗電纜(lan)等措(cuo)施(shi)(shi)，使輸(shu)電設備的(de)制(zhi)造成(cheng)(cheng)本增(zeng)大(da)。另外，根據電力規程(cheng)(cheng)要(yao)(yao)(yao)求，因所有金(jin)(jin)(jin)(jin)屬(shu)制(zhi)支(zhi)(zhi)(zhi)架(jia)(jia)(jia)在電場(chang)(chang)(chang)作(zuo)用(yong)(yong)(yong)(yong)(yong)(yong)下容易產生電量和(he)(he)電壓降，所以必須(xu)要(yao)(yao)(yao)求金(jin)(jin)(jin)(jin)屬(shu)支(zhi)(zhi)(zhi)架(jia)(jia)(jia)連入接地網(wang)，這就大(da)大(da)增(zeng)加(jia)工(gong)(gong)(gong)程(cheng)(cheng)量和(he)(he)工(gong)(gong)(gong)程(cheng)(cheng)周期。原(yuan)國(guo)家電力部曾于1994年在上海(hai)召開的(de)電纜(lan)標(biao)準會議上指出，在發(fa)使用(yong)(yong)(yong)(yong)(yong)(yong)有機復合(he)材(cai)料代替。

2、SMC玻(bo)(bo)璃(li)鋼(gang)(gang)電纜支架(jia)特點SMC復合材(cai)料(liao)（玻(bo)(bo)璃(li)鋼(gang)(gang)）是一種(zhong)(zhong)熱(re)固性(xing)熱(re)復合材(cai)料(liao)，SMC(英(ying)文全稱為(wei)Sheet Mould Compound)是由樹脂糊(hu)浸(jin)漬玻(bo)(bo)璃(li)纖維制成的一種(zhong)(zhong)片狀模塑料(liao)。采(cai)用(yong)SMC復合材(cai)料(liao)制造的電纜支架(jia)，其(qi)具(ju)有強度(du)高、韌性(xing)好、耐腐蝕、絕(jue)緣性(xing)能高、阻燃性(xing)好、不易老化，使用(yong)壽命長(chang)的優點，可取(qu)代(dai)金屬制的電纜支架(jia)。
