單導發熱電纜
1、芯線（金屬發熱絲(si)）：芯線為(wei)金屬合(he)金絲(si)組成，線性額定功(gong)率為(wei)18.5瓦特(te)每米。
2、絕(jue)緣層(ceng)(ceng)：森塔發(fa)熱(re)電(dian)纜(lan)耐高溫(wen)(wen)絕(jue)緣層(ceng)(ceng)采用雙層(ceng)(ceng)絕(jue)緣結構(gou)，絕(jue)緣層(ceng)(ceng)的質(zhi)量好壞直接影響到發(fa)熱(re)電(dian)纜(lan)的使用壽命(ming)，森塔耐高溫(wen)(wen)發(fa)熱(re)電(dian)纜(lan)絕(jue)緣層(ceng)(ceng)通(tong)過反復試驗，在140℃高溫(wen)(wen)下(xia)耐高溫(wen)(wen)層(ceng)(ceng)不(bu)(bu)變形、不(bu)(bu)萎縮。
3、接地線：接地線由8根直徑(jing)為(wei)0.4mm的(de)(de)鍍錫(xi)銅芯線組成。8根鍍錫(xi)銅芯線面積為(wei)1.0048m㎡，符合國際電工委員會(hui)IEC800規定的(de)(de)接地線不得小于1m㎡的(de)(de)規定。
4、金屬屏蔽層：發熱(re)電(dian)(dian)(dian)(dian)(dian)纜使用(yong)(yong)過程(cheng)(cheng)中，由于(yu)電(dian)(dian)(dian)(dian)(dian)流的作用(yong)(yong)，會在發熱(re)電(dian)(dian)(dian)(dian)(dian)纜周圍形(xing)成電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)場(chang)，電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)場(chang)超過100微特(te)斯(si)拉就會對人體(ti)健(jian)康及其它電(dian)(dian)(dian)(dian)(dian)器產(chan)生影響(xiang)。通過金屬屏蔽層的有效保護，把電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)場(chang)控制在線(xian)芯(xin)內，使之(zhi)不(bu)能向外擴散(san)，再由接地(di)(di)線(xian)將電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)場(chang)引(yin)入大(da)(da)地(di)(di)，使發熱(re)電(dian)(dian)(dian)(dian)(dian)纜與大(da)(da)地(di)(di)形(xing)成等(deng)電(dian)(dian)(dian)(dian)(dian)位。通過測試，森塔電(dian)(dian)(dian)(dian)(dian)地(di)(di)暖(nuan)產(chan)程(cheng)(cheng)的電(dian)(dian)(dian)(dian)(dian)場(chang)強度(du)值(zhi)是國家(jia)安(an)全(quan)范圍內的1/1000(國家(jia)規定的電(dian)(dian)(dian)(dian)(dian)場(chang)強度(du)是4000伏/m，森塔發熱(re)電(dian)(dian)(dian)(dian)(dian)纜實(shi)測數據為4伏/m)；磁(ci)(ci)感應強度(du)值(zhi)最(zui)高為13%，最(zui)低(di)6%（國家(jia)規定的磁(ci)(ci)感應強度(du)是100維(wei)特(te)斯(si)拉，實(shi)測數據為最(zui)高13維(wei)特(te)斯(si)拉），最(zui)低(di)6維(wei)特(te)斯(si)拉）。遠(yuan)遠(yuan)低(di)于(yu)國家(jia)標(biao)準，高于(yu)國家(jia)安(an)全(quan)規范，對人體(ti)無害，可放心(xin)使用(yong)(yong)。
5、外護套（pvc）：外護套為優質(zhi)PVC料。PVC具有很好的防(fang)腐蝕、防(fang)酸堿、抗老化作(zuo)用，并(bing)且(qie)100%防(fang)水。
主要使用范圍：
1、室內應用民用住宅（樓房、平房、別墅(shu)）供暖系(xi)統(tong)。
2、公用建筑（寫字樓、醫療機(ji)構、洗浴廣場、健身房等） 供(gong)暖系統。
3、特殊用途 畜牧業養殖保溫(wen)(wen)、（廠房、花(hua)房、蔬菜大棚、恒(heng)溫(wen)(wen)育雛室等）建筑保溫(wen)(wen)系統。
4、室外應用 室外道路(lu)融(rong)(rong)雪、土壤加熱、、天溝融(rong)(rong)雪、管(guan)道伴熱保溫(wen)(wen)、屋頂、樓梯、飛(fei)機跑(pao)道室外各類管(guan)路(lu)、線(xian)纜、儲罐(guan)等工(gong)業(ye)裝置的防凍、防凝、保溫(wen)(wen)。
