What is electric heating cable? As a high-tech product in the new era, electric heating cables are rarely understood. Many people may think that hearing this name is a technology that is far away from the lives of ordinary people. In fact, it is not the case. Although it does not have a strong sense of existence, it exists in every corner of our lives.
When it comes to electric heat tracing, we have to talk about electric heat tracing. It is an effective pipe insulation and antifreeze solution and has been widely used. Its working principle is to dissipate a certain amount of heat through the heating medium, and supplement the loss of the heated pipe through direct or indirect heat exchange, so as to meet the normal working requirements of temperature rise, heat preservation or antifreeze. The electric heating cable belongs to the heat tracing medium. After the electric heating cable is connected to the power supply (note that the wire core at the end must not be connected), the current forms a loop. Electric energy heats up the conductive material, and its resistance increases immediately. When the temperature of the core belt rises to a certain value, the resistance is so large that it almost blocks the current, and its temperature no longer rises. The heating system transfers heat. The power of the electric heating cable is mainly controlled by the heat transfer process, and the output power is automatically adjusted with the temperature of the heated system.
So what aspects can the electric heating cable be used for and what role does it play?
I believe everyone knows about civil solar energy and geothermal heating, but some people may not. Nowadays, many industrial pipelines that produce civil solar energy and geothermal heating have adopted electric heating belt technology, because it has the characteristics of high thermal efficiency, energy saving, simple design, and long service life. This series of products has three colors of red, black and brown. The construction temperature is as low as -40 degrees Celsius. The highest thermal stability value reaches 130 degrees Celsius, and the lowest is 99 degrees Celsius. It is insulated at a constant temperature of 75 degrees Celsius when the length is 100 meters. The minimum resistance is 20Ω, with shielding or explosion-proof type. The room temperature is 20 degrees Celsius and 2500VDC shake for one minute.
Of course, there are not only these aspects, but also pipelines in fire protection, petroleum, chemical, steel, electric power and other industries, storage tanks with heat preservation, anti-coagulation, and anti-freezing. Oil refining, metallurgy, pharmaceuticals, junction box transportation, etc. all have electric heating cables. It has a great support for the development of these industries. With its escort, the safety is greatly improved, and the price is cheap and greatly saved. The cost budget of these industries has been reduced so that more money can be invested in research and development. Explosion-proof, all-weather working performance, high reliability, long service life, saving steel, saving heat preservation materials, saving water resources, small workload, convenient and simple construction, small maintenance workload, high efficiency, and short-term return on cost, these are electric heating cables huge advantage.
To sum up, the electric heating cable is a protective measure that can protect the pipeline from being damaged due to excessive temperature or low temperature. This protective measure is not only green, energy-saving and environmentally friendly, but also can be automatically managed and installed. It can be cut and saved. Money is applicable to various environments and is a high-tech that is strongly supported by the state.
