What are the disadvantages of carbon fiber heating cable?

The physical characteristics of carbon fiber determine the high efficiency and energy saving of carbon fiber heating cable. It is the electrothermal material with the highest electrothermal conversion rate at present. Therefore, it is used in aviation and aerospace technology. Compared with other heating materials, the heating value of the same power is the largest and the heating time is faster. Good security. The current passing through a single wire is 0.8A, so you can directly touch the carbon fiber heating wire when it is electrified, and there is no feeling of electric shock. After the carbon fiber itself is electrified, 75% of the heat is radiated by far infrared rays. It has health care effect on human body. There is no electromagnetic radiation because the current is small. \ r \ Therefore, it can be considered that carbon fiber heating cable is the most energy-saving, safest and healthiest product. \ r \ Disadvantages: First, the price is higher than other products. \ r \ Secondly, because a single carbon fiber heating cable cannot achieve high enough power, there are many connectors. The technical bottleneck and service life of carbon fiber heating cable lies in whether the joint technology passes the standard or not. \ r \ Shengjia solar wing carbon fiber heating cable, as the leader of carbon fiber heating cable industry and the maker of carbon fiber heating cable industry standard, has an integrated joint process of cold and hot wires by injection molding to ensure that the joint part will not trip due to power failure, fire flashover or even leakage. And that lay efficiency is improved. As an underground concealed project, the patented cold hot wire connector of Shengjia solar wing carbon fiber heating cable has a service life of 50 years \ r \ n \ r \ nIn view of the questions answered upstairs, it is hereby corrected. \ r \ nOne: There is no floor heating product to cover. Unless it is made of ptc material, the indoor temperature will not come up after the ptc material is covered. \ r \ nTwo: The carbon fiber sheath is made of pvc and Teflon. These are professional cable materials, so the service life is not explained. You can find it online. The carbon fiber heating cable with PVC and PTFE sheath can withstand temperatures as high as 100 degrees. The maximum temperature of the heating cable we designed is 65 degrees, which is lower than the melting point temperature in working condition. At the same time, the corrosion resistance and aging resistance of PVC and Teflon determine that the service life of carbon fiber heating cable can reach more than 50 years, not to mention the aging resistance of carbon fiber heating wire itself, and the corrosion resistance can reach 1000 years. \ r \ Third: If the carbon fiber heating cable is divided into single-core and double-core, it is a big mistake. Only metal cables have such a name. It seems that there is no basic concept and understanding of carbon fiber heating cable. Because the current passing through each wire is very small, you can directly touch the carbon fiber wire when it is energized. So the electromagnetic radiation is almost zero, which is safe \ r \ Fourth, the standard power of a single carbon fiber heating cable is 230 watts, so how can a single wire reach 20kw? The maximum control power of each thermostat is less than 3000 watts. The 3000-watt thermostat can't be done well, so the thermostat manufacturers all drink northwest wind. . Ha ha. Too look down on the thermostat manufacturer.
