JFC 型恒功率串聯(lián)電熱帶
JFC 串聯(lián)型電熱帶是一種由芯線作發(fā)熱體的電伴熱產(chǎn)品,由于芯線單位長度的電阻和通過的電流均恒定,所以整根電伴熱帶首尾發(fā)熱均勻,輸出功率恒定。 Jfc type series connection heating cable is electric heating trace product which core wires act as heater.As the resistance per unit length and the current are constant,the power output of the whole heating cable from beginning to end is meaning and constant.

★注: 實(shí)際選用時(shí)應(yīng)根據(jù)管道長度、散熱量、工作電壓和芯線數(shù),計(jì)算芯線截面而定。
Note:When actually applying,choose suitable type cable according to the pipe lenght,heat loss,work voltage,number of core wires.and core wire's section areas.
