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.
