Problems solved by technology
[0002] So far, a special compensation cable for low-temperature resistant thermocouples has been widely used in metallurgy, casting, oil refining, chemical industry, machinery and other fields. If it is too low, the cable will be easily damaged under the impact of low temperature, and the signal transmission will be affected, causing the instrumentation system to fail to work normally under low temperature and emergencies, resulting in huge losses

The invention discloses a compensation cable special for a low temperature resistant thermocouple. The cable comprises two or more cable cores, compensation wire cores, a ceramic fluororubber outer sleeve, a copper-clad steel armored layer, a flame-retardant mica tape and a tinned wire woven shielding layer, wherein each cable core is formed by pressing and wrapping a SiO2 ceramic insulated layer on a nickel-chromium-nickel-silicone alloy conductor; the upper and lower gaps between every two adjacent cable cores are respectively provided with a compensation wire core; the copper-clad steel armored layer, the flame-retardant mica tape and the ceramic fluororubber outer sleeve are pressed and wrapped on the tinned wire woven shielding layer sequentially from inside to outside. The temperature loss of the cable is compensated through the compensation wire cores, so that a product can normally work in an environment with the temperature between 80 DEG C below zero to 500 DEG C in a long term, and good flame-retardant performance and radiation resistant performance are realized, the cracking phenomenon caused by temperature shock is reduced, the signal smooth is ensured, and the service life is prolonged.
Description
technical field [0001] The invention relates to cables, in particular to a special compensating cable for low temperature resistant thermocouples. Background technique [0002] So far, a special compensation cable for low-temperature resistant thermocouples has been widely used in metallurgy, casting, oil refining, chemical industry, machinery and other fields. If it is too low, the cable will be easily damaged under the impact of low temperature, and the signal transmission will be affected, which will cause the instrumentation system to not work normally at low temperature and emergencies, causing huge losses. Contents of the invention [0003] Based on the above situation, the object of the present invention is to provide a special compensation cable for low temperature resistant thermocouples. [0004] The scheme of the present invention is as follows: a special compensation cable for low temperature resistant thermocouples, including two or more cable cores, compensa...
