Working principle：


Power busline of constant power parallel connection electrical heating band is two or three roots parallel insulated copper wire, wind nickel chromium wire on the skeleton, electrical heating wires is
intersected by each certain distance that is connect the“heating segment” with the busline, to form continuous parallel connection resistance, once the busline is powered, all parallel resistance heats,
thus forming a continuous electrical heating band.
The heating power of per unit length of the constant power electrical heating band is constant，used in the range of maximum using length，the greater the total power output is, the electrical heating band can be arbitrarily cut in accordance with the actual needs.

Characteristics：


◆　The maximum using length of three phase parallel connection electrical heating band is about 2~3 times than that of single phase electrical heating band；
◆　The anti-corrosive layer has the performance of oil-resistance, acidresistance and corrosion-resistance;
◆　All materials are non-combustible（oxygen index is ＞95 or more）；
◆　The minimum bending radius is 5 times of the electrical heating band thickness
