在這個網(wang)絡(luo)時(shi)代(dai)，各式各樣關于電纜的新聞話語有(you)很(hen)多(duo)，你聽(ting)到過(guo)多(duo)少呢?

一(yi)、電(dian)纜會發(fa)生輻(fu)射?

電(dian)(dian)(dian)纜(lan)確實是(shi)(shi)有(you)輻(fu)(fu)射(she)(she)，卻不知(zhi)道真理的客觀性是(shi)(shi)只(zhi)要(yao)是(shi)(shi)插電(dian)(dian)(dian)的物件全是(shi)(shi)有(you)輻(fu)(fu)射(she)(she)，如380V的電(dian)(dian)(dian)纜(lan)也(ye)是(shi)(shi)有(you)輻(fu)(fu)射(she)(she)，但其(qi)輻(fu)(fu)射(she)(she)基(ji)本上為零，絕大(da)多(duo)數(shu)可以(yi)忽視，而且電(dian)(dian)(dian)纜(lan)的輻(fu)(fu)射(she)(she)遠低于手機(ji)輻(fu)(fu)射(she)(she)，倘若(ruo)(ruo)的確擔(dan)憂電(dian)(dian)(dian)纜(lan)輻(fu)(fu)射(she)(she)，那(nei)么(me)建(jian)議先把手機(ji)扔了。假(jia)若(ruo)(ruo)擔(dan)憂的是(shi)(shi)電(dian)(dian)(dian)纜(lan)導致的磁(ci)(ci)場，覺得(de)磁(ci)(ci)場會(hui)對人體造(zao)成什么(me)危害(hai)，那(nei)么(me)地磁(ci)(ci)場方向就(jiu)更(geng)恐怖了。因此覺得(de)“電(dian)(dian)(dian)纜(lan)有(you)輻(fu)(fu)射(she)(she)會(hui)傷(shang)害(hai)身體健康”實在是(shi)(shi)想太多(duo)了。

阻燃電纜

二、阻(zu)燃電纜為什么不易點燃?

錯(cuo)!阻燃(ran)(ran)電(dian)纜(lan)(lan)的阻燃(ran)(ran)是(shi)(shi)指在(zai)電(dian)纜(lan)(lan)安全(quan)生(sheng)產事(shi)故造成時，能(neng)(neng)夠(gou)傳導阻滯、延遲時間火(huo)焰沿著(zhu)電(dian)纜(lan)(lan)的擴(kuo)散和蔓延，盡量減少電(dian)纜(lan)(lan)安全(quan)事(shi)故范圍(wei)擴(kuo)展，該類型的電(dian)纜(lan)(lan)具(ju)有(you)著(zhu)火(huo)后自熄的特(te)性。防火(huo)安全(quan)電(dian)纜(lan)(lan)是(shi)(shi)指在(zai)電(dian)纜(lan)(lan)安全(quan)生(sheng)產事(shi)故中，該電(dian)纜(lan)(lan)產品(pin)能(neng)(neng)夠(gou)在(zai)外部火(huo)焰依然(ran)引燃(ran)(ran)的情況下，能(neng)(neng)夠(gou)鍥而不(bu)舍一定時間的一切(qie)(qie)正常(chang)運作，保(bao)持電(dian)纜(lan)(lan)線路一致(zhi)性并保(bao)持線路機械設備的一切(qie)(qie)正常(chang)運作。

三(san)、電纜護套越厚越好?

并不(bu)是，電(dian)(dian)(dian)(dian)纜護套(tao)太厚會(hui)提高(gao)電(dian)(dian)(dian)(dian)纜鋪(pu)裝難易度(du)，現如今(jin)電(dian)(dian)(dian)(dian)纜鋪(pu)裝以橋架或(huo)電(dian)(dian)(dian)(dian)線(xian)管(guan)為核心，現如今(jin)許(xu)多(duo)企(qi)業(ye)全是在(zai)實行電(dian)(dian)(dian)(dian)纜要求(qiu)緊，直(zhi)徑(jing)小，在(zai)鋪(pu)裝整個(ge)過程里能有(you)(you)空隙，釋放出(chu)來(lai)電(dian)(dian)(dian)(dian)力(li)能源，保證電(dian)(dian)(dian)(dian)纜外(wai)護線(xian)套(tao)不(bu)容易遭(zao)受危害(hai)，要不(bu)然，給建(jian)筑企(qi)業(ye)和電(dian)(dian)(dian)(dian)纜鋪(pu)裝造成一(yi)定(ding)艱辛(xin)。在(zai)夏季(ji)，工作(zuo)溫(wen)度(du)很有(you)(you)可能升高(gao)，這類溫(wen)度(du)很有(you)(you)可能依據外(wai)護層(ceng)釋放出(chu)來(lai)出(chu)來(lai)，護線(xian)套(tao)厚薄(bo)提高(gao)，電(dian)(dian)(dian)(dian)力(li)能源沒(mei)法釋放出(chu)來(lai)，很有(you)(you)可能傷害(hai)電(dian)(dian)(dian)(dian)纜應用限期，因(yin)高(gao)壓聚(ju)乙(yi)烯(xi)在(zai)熱的作(zuo)用下(xia)，使絕(jue)緣套(tao)管(guan)造成一(yi)系列的物理和化學變化，缺少了(le)原先的高(gao)品(pin)質(zhi)特(te)點(dian)，導致體積電(dian)(dian)(dian)(dian)阻率能明顯減少，甚至會(hui)產生短路故障常見故障，因(yin)而選擇電(dian)(dian)(dian)(dian)纜時，電(dian)(dian)(dian)(dian)纜的厚薄(bo)一(yi)定(ding)要適當。
