在一些(xie)電(dian)伴(ban)(ban)熱(re)(re)帶(dai)施(shi)工項(xiang)目中，為了安(an)全用電(dian)的(de)需要，客戶會傾向于24V電(dian)伴(ban)(ban)熱(re)(re)帶(dai)的(de)選型，雖然國內大多儲罐管道上使用的(de)是220v電(dian)壓(ya)的(de)電(dian)伴(ban)(ban)熱(re)(re)帶(dai)供(gong)電(dian)，但是有(you)些(xie)場(chang)合會使用到(dao)低電(dian)壓(ya)的(de)電(dian)伴(ban)(ban)熱(re)(re)帶(dai)，例如24電(dian)伴(ban)(ban)熱(re)(re)帶(dai)，下面就給大家介紹一下。

　　24V電伴熱帶的使用距離不是很長，一般在20米左右，如果電伴熱帶工程項目中使用的距離超過這一距離，就不適宜使用24V電伴熱帶，工業用的220v電伴熱帶可以達到100米

　　在安(an)(an)裝、布線(xian)(xian)以及施(shi)(shi)工(gong)(gong)上(shang)(shang)(shang)提(ti)供更(geng)大(da)的(de)便捷(jie)性(xing)。假如您(nin)有(you)一(yi)個施(shi)(shi)工(gong)(gong)項目，在安(an)(an)全(quan)考慮上(shang)(shang)(shang)，您(nin)可(ke)能希望采用24v的(de)電(dian)(dian)(dian)壓(ya)進行供電(dian)(dian)(dian)，但(dan)在實際設(she)計、安(an)(an)裝施(shi)(shi)工(gong)(gong)過程中您(nin)會發現，因為長度的(de)限制，多出了非(fei)常多的(de)接線(xian)(xian)點(dian)，這(zhe)就非(fei)常不(bu)利于電(dian)(dian)(dian)伴(ban)(ban)熱(re)帶(dai)的(de)安(an)(an)裝施(shi)(shi)工(gong)(gong)，甚至對布線(xian)(xian)也(ye)有(you)著(zhu)很大(da)的(de)影響，更(geng)多的(de)接線(xian)(xian)點(dian)對后(hou)期的(de)維護也(ye)提(ti)出了更(geng)大(da)的(de)挑戰，除此之外(wai)，成本上(shang)(shang)(shang)也(ye)會上(shang)(shang)(shang)浮不(bu)少(shao)。所以，在選(xuan)擇電(dian)(dian)(dian)壓(ya)等級上(shang)(shang)(shang)，24v電(dian)(dian)(dian)伴(ban)(ban)熱(re)帶(dai)與220v電(dian)(dian)(dian)伴(ban)(ban)熱(re)帶(dai)的(de)取舍主要(yao)還要(yao)綜合全(quan)局，若管(guan)(guan)線(xian)(xian)布局短、管(guan)(guan)線(xian)(xian)線(xian)(xian)路上(shang)(shang)(shang)電(dian)(dian)(dian)源點(dian)較多就完全(quan)可(ke)以采用24v的(de)伴(ban)(ban)熱(re)帶(dai)進行安(an)(an)裝，總而(er)言之，您(nin)還是需(xu)要(yao)根據(ju)管(guan)(guan)道以及伴(ban)(ban)熱(re)帶(dai)的(de)發熱(re)需(xu)求(qiu)來定型。

　　您可以根據(ju)維持溫度(du)(du)來(lai)決定(ding)選(xuan)用的(de)電(dian)(dian)(dian)伴熱(re)帶(dai)(dai)型號以及(ji)長度(du)(du)值;其(qi)次(ci)電(dian)(dian)(dian)伴熱(re)帶(dai)(dai)的(de)承受溫度(du)(du)一(yi)定(ding)要高于環境(jing)或者管(guan)道溫度(du)(du)值，否則電(dian)(dian)(dian)伴熱(re)帶(dai)(dai)會出(chu)現損(sun)毀情(qing)況。需要提醒的(de)是要嚴格(ge)按照電(dian)(dian)(dian)伴熱(re)帶(dai)(dai)廠(chang)家(jia)為您提供的(de)24v電(dian)(dian)(dian)伴熱(re)帶(dai)(dai)管(guan)線圖或者220v電(dian)(dian)(dian)伴熱(re)帶(dai)(dai)施工圖，設計圖中會明確標定(ding)電(dian)(dian)(dian)源接線盒以及(ji)三通尾端(duan)的(de)位置(zhi)，一(yi)定(ding)要嚴格(ge)遵守施工。
