天溝屋(wu)面防(fang)凍保(bao)溫帶-天津天溝屋(wu)面防(fang)凍保(bao)溫帶-旭誠電伴(ban)熱帶

一、電伴熱帶較大電路長度，這是什么意思？ 電伴熱帶較大電路長度即一個電源點可帶動的電伴熱帶長度。自控溫電伴熱帶的(de)(de)(de)較大(da)長(chang)(chang)度是基(ji)于某一(yi)規格的(de)(de)(de)斷(duan)路器的(de)(de)(de)大(da)小再(zai)考慮一(yi)定的(de)(de)(de)沖擊電(dian)流而定的(de)(de)(de)。 而另一(yi)種(zhong)恒(heng)功(gong)率(lv)電(dian)熱(re)帶功(gong)率(lv)恒(heng)定，發熱(re)溫度高。恒(heng)功(gong)率(lv)電(dian)伴(ban)熱(re)帶隨著(zhu)長(chang)(chang)度的(de)(de)(de)增(zeng)加(jia)，電(dian)伴(ban)熱(re)帶尾(wei)端(duan)的(de)(de)(de)壓降也將增(zeng)加(jia)。根(gen)據電(dian)伴(ban)熱(re)相(xiang)關(guan)標準，恒(heng)功(gong)率(lv)電(dian)伴(ban)熱(re)帶尾(wei)端(duan)功(gong)率(lv)降不得超過(guo)輸入(ru)端(duan)的(de)(de)(de)20%。因此此時的(de)(de)(de)電(dian)伴(ban)熱(re)帶長(chang)(chang)度就規定為恒(heng)定功(gong)率(lv)電(dian)纜的(de)(de)(de)較大(da)長(chang)(chang)度。

電伴熱帶應用(yong)埋(mai)地管道保溫使用(yong)什么型號呢(ni)

　　電(dian)(dian)伴(ban)熱(re)(re)帶應用(yong)埋地(di)管(guan)道(dao)(dao)保溫(wen)使用(yong)什么型(xing)號(hao)呢，在為埋地(di)管(guan)道(dao)(dao)使用(yong)電(dian)(dian)伴(ban)熱(re)(re)產(chan)品(pin)保溫(wen)時，有用(yong)戶有這樣(yang)(yang)的疑問埋地(di)管(guan)道(dao)(dao)使用(yong)的電(dian)(dian)伴(ban)熱(re)(re)帶產(chan)品(pin)保溫(wen)，使用(yong)的型(xing)號(hao)要(yao)一(yi)樣(yang)(yang)嗎，由于(yu)管(guan)道(dao)(dao)和所需(xu)要(yao)的保溫(wen)需(xu)求不(bu)(bu)一(yi)樣(yang)(yang)，所以型(xing)號(hao)選擇業不(bu)(bu)需(xu)要(yao)一(yi)樣(yang)(yang)的，只要(yao)適(shi)合管(guan)道(dao)(dao)保溫(wen)就(jiu)可以了。其次對(dui)埋地(di)管(guan)道(dao)(dao)電(dian)(dian)伴(ban)熱(re)(re)帶安裝(zhuang)的選擇不(bu)(bu)僅考慮(lv)電(dian)(dian)伴(ban)熱(re)(re)的長度、現場環境(jing)溫(wen)度還需(xu)考慮(lv)電(dian)(dian)伴(ban)熱(re)(re)帶的耐腐性和承(cheng)受力。由于(yu)電(dian)(dian)伴(ban)熱(re)(re)帶安裝(zhuang)時長期埋于(yu)地(di)下，防腐性能(neng)是電(dian)(dian)伴(ban)熱(re)(re)帶產(chan)品(pin)必須要(yao)考慮(lv)的。外護套防腐絕緣層使用(yong)聚烯烴或(huo)氟塑料(liao)，能(neng)起到良好的防腐效(xiao)果。
