The power generatrix wire is 2 parallel insulative copper wires. Heating threads are wound around the inner jacket insulation layer. Every certain distance the heating thread is welded to the generatrix,which makes the continuous parallel connection resistance. When the generatrix is powered, the parallel connection resistance begin to heat. This makes a continuousheating belt.

Table 2-1: Main Technical Parameters of JFB- 口 /2 Type Electric heat cable
The heat output per length unit out of the constant wattage heating cable is fixed and constant.The longer the heating cable, the stronger the power is output. The electric heating belt can be cut flexibly according to the actual needs. And it is flexible and can be laid closely on the pipe surface. The outer brade layer can execute the function of heat transmitting and radiating, to enhance the general intensity of the heating belt. It can also be earthed.
一般用于小管线或管网系统短管线的伴热保温。
Itiscommonly used for thermal insulation of the small pipes or the short pipes of the pipe
