。 我們堅持高質量服務,立志高技術創新,追求高速度發展。一直秉承“為客戶服務并且創造價值”的宗旨,堅持“創新務實,客戶至上”的工作準則,為工廠提供優異產品和系統解決方案。目前,卓晟環保電線主營的UL電子線在全國備受客戶的熱捧。本(ben)公司(si)秉著誠信經營的理念對產(chan)品進行(xing)生產(chan)銷售,強化過程管理,建設品質良好工程。
UL1275-UL20276-UL20379。 我司屬于有限責任公司,坐落在南海區桂城街道平洲夏東孔溪。公司要求員工“基本技能要掌握,***技能要求精”,其中也不乏高水平高技術工作人員。本公司自創立以來一直以質量和信譽為本,為廣大工廠提供質優價廉的UL電子線,并(bing)與諸(zhu)多企業真誠(cheng)合作,被廣大(da)用戶所(suo)認知(zhi)。
電(dian)(dian)力電(dian)(dian)纜(lan)在施工(gong)中,有(you)采用(yong)鋼(gang)(gang)支架的(de),有(you)采用(yong)鋼(gang)(gang)質保護管的(de),有(you)采用(yong)電(dian)(dian)纜(lan)卡與(yu)架空敷設的(de),凡是在電(dian)(dian)力電(dian)(dian)纜(lan)周(zhou)圍(wei)形(xing)成(cheng)(cheng)鋼(gang)(gang)(鐵)性(xing)閉合回路(lu)的(de),均有(you)可能(neng)(neng)形(xing)成(cheng)(cheng)渦(wo)(wo)流,特別是在大電(dian)(dian)流電(dian)(dian)力電(dian)(dian)纜(lan)系統中,渦(wo)(wo)流更大。在電(dian)(dian)力電(dian)(dian)纜(lan)施工(gong)時,***采取措(cuo)施,使電(dian)(dian)纜(lan)周(zhou)圍(wei)不能(neng)(neng)形(xing)成(cheng)(cheng)鋼(gang)(gang)(鐵)性(xing)閉合回路(lu),防止電(dian)(dian)纜(lan)引起渦(wo)(wo)流現象發生。
電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)轉(zhuan)彎(wan)引起的(de)(de)機(ji)械(xie)(xie)性損(sun)(sun)傷(shang)(shang)問題由(you)于電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)外徑較(jiao)大,運輸、敷設較(jiao)為困難(nan),電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)對轉(zhuan)彎(wan)半(ban)徑的(de)(de)要求也比較(jiao)嚴格。電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)在(zai)(zai)施(shi)工(gong)中(zhong),如(ru)果轉(zhuan)彎(wan)角度(du)(du)過(guo)大,可(ke)能使(shi)(shi)導體內部(bu)受(shou)到機(ji)械(xie)(xie)損(sun)(sun)傷(shang)(shang),而機(ji)械(xie)(xie)損(sun)(sun)傷(shang)(shang)因被電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)絕緣強度(du)(du)下降,直到出現故(gu)障(zhang),施(shi)工(gong)中(zhong)發現一次電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)頭(tou)故(gu)障(zhang),在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)頭(tou)制作時,三根電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)頭(tou)長(chang)度(du)(du)一致,與設備連(lian)接時由(you)于受(shou)地形(xing)限(xian)制,中(zhong)相電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)頭(tou)偏長(chang)而成為拱形(xing),電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)頭(tou)根部(bu)受(shou)損(sun)(sun)放電(dian)(dian)(dian)(dian)(dian)。后(hou)采取措施(shi),在(zai)(zai)設備的(de)(de)連(lian)接,適當(dang)縮短中(zhong)相電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)頭(tou)連(lian)接長(chang)度(du)(du),使(shi)(shi)三相電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)頭(tou)均不受(shou)外力,實踐證明運行效果良好。由(you)此可(ke)見,電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)施(shi)工(gong)過(guo)程(cheng)中(zhong),要盡可(ke)能減(jian)少電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)受(shou)到的(de)(de)扭力,在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)轉(zhuan)彎(wan)和裕留電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)時,讓電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)處于自然彎(wan)曲,內部(bu)機(ji)械(xie)(xie)損(sun)(sun)傷(shang)(shang)現象。
電(dian)力纜(lan)防潮問題(ti)運行經(jing)驗表(biao)明,中、低(di)壓(ya)電(dian)力電(dian)纜(lan)故障大(da)(da)部(bu)(bu)分為電(dian)纜(lan)中間(jian)接(jie)(jie)頭(tou)(tou)(tou)和(he)終端(duan)頭(tou)(tou)(tou)故障,而(er)中間(jian)接(jie)(jie)頭(tou)(tou)(tou)和(he)終端(duan)頭(tou)(tou)(tou)故障則大(da)(da)部(bu)(bu)分是因密(mi)封不良,潮氣侵入而(er)造成絕緣強度下降,而(er)中、低(di)壓(ya)電(dian)力電(dian)纜(lan)網(wang)(wang)多采(cai)用樹枝狀供電(dian)方式,電(dian)纜(lan)終端(duan)頭(tou)(tou)(tou)數量較多,因此把好電(dian)纜(lan)終端(duan)頭(tou)(tou)(tou)和(he)中間(jian)接(jie)(jie)頭(tou)(tou)(tou)堵漏密(mi)封關是保證電(dian)纜(lan)安(an)全可靠(kao)運行的重要(yao)措施之(zhi)一。在(zai)公用中、低(di)壓(ya)電(dian)力電(dian)纜(lan)網(wang)(wang)上,由(you)于(yu)三相負荷不是相等(deng)的,因此,如果采(cai)用有金(jin)屬(shu)護(hu)層的電(dian)纜(lan),***考慮(lv)金(jin)屬(shu)護(hu)層的接(jie)(jie)地問題(ti),并保證在(zai)金(jin)屬(shu)護(hu)層的任一點非(fei)接(jie)(jie)地處的正常感應電(dian)壓(ya)不得大(da)(da)于(yu)100V。我認為,在(zai)中、低(di)壓(ya)電(dian)纜(lan)網(wang)(wang)中,所有電(dian)纜(lan)接(jie)(jie)頭(tou)(tou)(tou)處均應設置接(jie)(jie)地極(網(wang)(wang)),并使(shi)金(jin)屬(shu)護(hu)層可靠(kao)接(jie)(jie)地。

電(dian)纜(lan)(lan)(lan)電(dian)線(xian)(xian)在施工(gong)(gong)工(gong)(gong)地(di),有(you)(you)采用鋼(gang)固定支架的(de),有(you)(you)采用鋼(gang)質維護(hu)保養管的(de),有(you)(you)采用電(dian)纜(lan)(lan)(lan)卡與空(kong)架鋪(pu)裝的(de),只要(yao)是(shi)在電(dian)纜(lan)(lan)(lan)電(dian)線(xian)(xian)附近(jin)造成(cheng)鋼(gang)(鐵)性閉合回路的(de),均(jun)有(you)(you)可能造成(cheng)渦流,尤其是(shi)在大(da)(da)電(dian)總流量電(dian)纜(lan)(lan)(lan)電(dian)線(xian)(xian)系統中,渦流更大(da)(da)。在電(dian)纜(lan)(lan)(lan)電(dian)線(xian)(xian)建(jian)筑(zhu)施工(gong)(gong)時(shi),盡量采取措施,使電(dian)纜(lan)(lan)(lan)附近(jin)不能造成(cheng)鋼(gang)(鐵)性閉合回路,防止(zhi)電(dian)纜(lan)(lan)(lan)導致(zhi)渦流情況(kuang)造成(cheng)。
電(dian)(dian)(dian)纜(lan)(lan)電(dian)(dian)(dian)線的轉彎導致的機(ji)(ji)械(xie)性損傷(shang)難點由于(yu)電(dian)(dian)(dian)纜(lan)(lan)電(dian)(dian)(dian)線直徑挺(ting)大,運輸(shu)、鋪裝(zhuang)較為艱(jian)辛(xin),電(dian)(dian)(dian)纜(lan)(lan)電(dian)(dian)(dian)線對少小轉彎半(ban)徑的要求也比較苛(ke)刻。電(dian)(dian)(dian)纜(lan)(lan)電(dian)(dian)(dian)線在施(shi)工(gong)(gong)工(gong)(gong)地(di)(di)(di),倘若(ruo)轉彎角度(du)(du)過(guo)大,可(ke)能使電(dian)(dian)(dian)導體內部遭到工(gong)(gong)業設備危害,而工(gong)(gong)業設備危害因被電(dian)(dian)(dian)纜(lan)(lan)電(dian)(dian)(dian)纜(lan)(lan)護套抗拉強度(du)(du)減少,直到出現常見問(wen)題,施(shi)工(gong)(gong)工(gong)(gong)地(di)(di)(di)發現一(yi)次(ci)電(dian)(dian)(dian)纜(lan)(lan)終(zhong)(zhong)端(duan)頭(tou)常見問(wen)題,在電(dian)(dian)(dian)纜(lan)(lan)頭(tou)制作時,三(san)根電(dian)(dian)(dian)纜(lan)(lan)終(zhong)(zhong)端(duan)頭(tou)長(chang)度(du)(du)一(yi)致,與設備連接(jie)時由于(yu)受(shou)地(di)(di)(di)形(xing)地(di)(di)(di)貌限制,中相(xiang)(xiang)電(dian)(dian)(dian)纜(lan)(lan)終(zhong)(zhong)端(duan)頭(tou)太長(chang)而變為弧型,電(dian)(dian)(dian)纜(lan)(lan)終(zhong)(zhong)端(duan)頭(tou)根部損害蓄電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)。后(hou)采取措施(shi),在機(ji)(ji)械(xie)設備的連接(jie),適當(dang)降低中相(xiang)(xiang)電(dian)(dian)(dian)纜(lan)(lan)終(zhong)(zhong)端(duan)頭(tou)連接(jie)長(chang)度(du)(du),使三(san)相(xiang)(xiang)電(dian)(dian)(dian)纜(lan)(lan)終(zhong)(zhong)端(duan)頭(tou)均不(bu)容易遭受(shou)外力,社(she)會經驗運行預期(qi)效果。

無鹵電子線適用于額定電壓450-750V以下、阻燃、低煙、環保安全要求高的場所等。如高層建筑、車站、地鐵、體育館、別墅、家庭住宅、酒店、醫院、辦公樓、機場、醫院、大型圖書館、學校、商場等人口密集場所。低煙無鹵電子線的優勢在傳統的PVC電線中,當發(fa)生火災時,PVC混合物(wu)容易(yi)分解和(he)逸(yi)出大(da)量毒性強、腐(fu)蝕性強的(de)HCL氣體(ti),產(chan)生大(da)量劇毒煙霧(wu),造(zao)(zao)成(cheng)重大(da)生命財(cai)產(chan)損(sun)失,給救援工作帶(dai)來(lai)很大(da)困難。為了(le)盡可能(neng)減(jian)少火災和(he)火災造(zao)(zao)成(cheng)的(de)二次(ci)傷(shang)害(hai),研(yan)究發(fa)現,改(gai)變產(chan)品使用的(de)外部(bu)材料和(he)工藝可有效解決這一問題。
無鹵(lu)(lu)電(dian)子線電(dian)纜(lan)燃(ran)(ran)燒過(guo)程(cheng)中釋放的(de)(de)(de)煙(yan)(yan)霧(wu)量(liang)小(xiao),主要是(shi)所有材料都不含鹵(lu)(lu)素。鹵(lu)(lu)素電(dian)纜(lan)在火災(zai)(zai)中的(de)(de)(de)毒性(xing)是(shi)可怕的(de)(de)(de)。如果30分鐘(zhong)內可致人死亡的(de)(de)(de)氣(qi)體濃度的(de)(de)(de)毒性(xing)為(wei)1,無鹵(lu)(lu)聚(ju)合物的(de)(de)(de)毒性(xing)指(zhi)數(shu)為(wei)0.79,則聚(ju)氯(lv)乙(yi)烯的(de)(de)(de)毒性(xing)指(zhi)數(shu)為(wei)15.01。而(er)火災(zai)(zai)過(guo)程(cheng)中,濃煙(yan)(yan)彌漫,使(shi)災(zai)(zai)民無法辨別方(fang)向,延長了在火災(zai)(zai)中的(de)(de)(de)停(ting)留時(shi)間。根據相關數(shu)據,當透過(guo)率(lv)為(wei)70%時(shi),裸(luo)眼視覺識別能力僅(jin)為(wei)5m左(zuo)右。PVC燃(ran)(ran)燒煙(yan)(yan)氣(qi)的(de)(de)(de)透光率(lv)小(xiao)于15%,即煙(yan)(yan)氣(qi)的(de)(de)(de)裸(luo)視距(ju)僅(jin)為(wei)2m左(zuo)右。煙(yan)(yan)的(de)(de)(de)另一個特(te)點是(shi)隨(sui)著風的(de)(de)(de)流動而(er)迅速(su)地(di)傳播,速(su)度可達20米(mi)/分鐘(zhong)以上。可見,使(shi)用無鹵(lu)(lu)低煙(yan)(yan)電(dian)線電(dian)纜(lan)是(shi)保證(zheng)***關鍵。
通過無鹵(lu)電子線(xian)阻燃(ran)技(ji)術的(de)(de)革(ge)新而推出了(le)新型高性能環保(bao)型電線(xian)。很(hen)好地解決了(le)PVC裝飾線(xian)的(de)(de)缺點。無鹵(lu)、低煙、阻燃(ran)、優(you)良的(de)(de)短(duan)路負(fu)載能力是(shi)裝修的(de)(de)明(ming)智選擇。我們相信,隨著人(ren)們生(sheng)活(huo)條件的(de)(de)改善,人(ren)們越(yue)來(lai)越(yue)重視健康、安全和環境保(bao)護(hu)。當(dang)新型高性能環保(bao)布絲完全取代傳統PVC絲的(de)(de)那***即將到來(lai)。
