In the electric heating system, is divided into self regulating temperature electric heat cable and constant wattage electric heat cable two kinds, these two kinds of specifications of the electric accompanying heat is used in different areas, such as self-regulating electric heating cable, because of the self regulating electric heat tape cable with automatic adjustment function, can be arbitrarily cut and can be cross-overlapping use, is used in complexity pipeline mostly, there are the valves, groove pools and water pipes and so on.

                      The advantages of constant wattage electric heat tape cable are many, its power supply bus is two parallel copper wire, in the middle of the green layer winding electric heat wire, and the electric heat wire every certain distance and bus connection, forming a continuous parallel resistance. After the busbar is energized, the parallel resistance heats up, thus forming a continuous heating tape cable. It has the advantages of long service length, high temperature resistance and corrosion resistance.

                 Constant wattage power electric heating cable core line to use the purity of 99.99 electroplated copper wire, high purity, fine organization, oxygen content is very low. No air holes, trachoma, loose, better conductivity, instead of the traditional tinned copper stranded wire, good conductivity, heat conduction, corrosion resistance. Constant power electric heat tape cable softness good, can be close to the pipeline surface. Unit length heat constant, the longer the use of the output power is greater, according to the actual needs of the arbitrary cut length. Widely used in petroleum, chemical industry, electric power, metallurgy, pipeline, valve and other installations of anti-freezing, anti-suspicion.

                    The constant power wattage electric heating cable belt to have other accompanies the heat product not to have the use length long and the high temperature resistance and so on the role, in the general situation can be applied in the temperature in -30 ℃ about the alpine area, and can let the medium be in the long term flow state, is very simple and the safety, the constant power electric heating tape cable belt to work the temperature in 130'℃, the application is wide, the installation is simple, is a worthy to have accompanies the heat preservation product.
