With the advent of winter, the low temperature environment to industrial production, building facilities and pipeline system normal operation has brought a serious challenge. In recent years, electric accompanied by tropical technology as a kind of high efficiency, energy saving anti-freezing and heat preservation solution, gradually become the first choice of each industry to deal with the problem of low temperature.

 　　Electric heating cable, also known as electric heat trace tape or electric heating tape, is a kind of device that generates heat through electric energy, mainly used for pipeline, storage tank, equipment and other facilities of heat preservation and anti-freezing. Its working principle is the use of electric energy into thermal energy, through the accompanying tropical uniform heat, maintain the normal working temperature of the pipeline or equipment in the low temperature environment, to prevent freezing, icing or medium solidification.

              Electric heating cable mainly divided into self-limiting temperature electric accompanied by tropical and constant power electric accompanied by tropical two types. The self-limiting temperature electric heating cable to be able to adjust the heating power automatically according to the environment temperature, has the energy-saving, the safety, the installation is simple and so on the advantages; The constant power electric heating cable is suitable for the occasion which needs to be heated constantly, the heating power is stable, is suitable for the long-distance range pipeline heat preservation.　　

　　       Electric heating cable technology has been widely used in petrochemical industry, building heating, fire pipeline, water supply and drainage system, food processing and other fields. In petrochemical industry, electric heating cable for preventing the medium in the pipeline due to low temperature and solidification, to ensure the continuity of the production process; in the field of construction, electric heating trace cable is used for the roof melting snow, the ground antifreeze and pipeline heat preservation, to enhance the building safety and comfort; in the fire fighting system, electric heating trace cable to prevent the fire fighting pipeline freezing, to ensure the reliability of the emergency response system.

                    Compared with traditional steam heat tracing or hot water heat tracing, electric heat tracing technology has significant energy-saving advantages. The electric accompanies the tropical belt directly to use the electric energy to heat, the heat efficiency is high, the energy loss is low, and does not need the additional boiler or the steam equipment, reduces the energy waste and the environmental pollution. In addition, the electric accompanies the tropical tape can adjust the heating power flexibly according to the actual demand, further reduces the energy consumption, conforms to the green environmental protection development trend.
　　            Electric accompanied by tropical technology with its high efficiency, energy saving, environmental protection characteristics, is becoming the mainstream choice in the field of winter antifreeze heat preservation. With the continuous progress of the technology and the expansion of the application scope, the electric accompanied by the heat will provide more reliable low-temperature solutions for various industries, and help to realize the goal of sustainable development.
