Why can't we wind the constant power heating band when installing it

The constant power heating strip is a constant power heating strip product. The output power of the electric heating belt is always constant after being electrified, and will not change with the change of the external environment, thermal insulation materials and heat tracing materials. Therefore, whether in parallel or in series, the unit heating capacity of constant power electric belt is not constant. The longer the electric belt is used, the greater the total power output.
The parallel connection of heating belt can be cut according to the actual length on site, and the length of heating joint shall not be less than one. However, this series of power cables cannot be shortened and need to be customized. The redundant part of the series constant power cable can be wound on other pipes or equipment at equal intervals, so the service length of each pipe should be calculated during selection; If the length of a single cable is required to be shorter, other types of heating tape can be selected. In terms of installation, the constant power cable is mainly laid directly. During the installation process, it is not allowed to cross and overlap, and it is not allowed to knot to prevent the resistance wires from squeezing together. This is determined by the structure and working principle of constant power electric belt. Because the constant power electric heating belt uses the traditional resistance wire heating method, it cannot control the temperature by itself, and must be controlled by the explosion-proof temperature controller. If the constant power electric heating belt Rongjia is installed, the temperature of the material and the heating wire will rise, and the heating wire will be burned, resulting in the failure of the entire Shentong heating belt system.
