Problems solved by technology
However, with the widespread use of the cable, some problems also appear, such as the requirement for the tensile resistance of the wire is also increasing, and it is connected with the display instrument to form a multi-point temperature measurement system. The insulation and sheath of ordinary compensation wires and other mechanical and physical Performance Under the influence of high temperature, oxidation, and impact force, the performance of the wire is reduced, resulting in deviations in the transmission of electrical signals, which cannot meet the needs of accurate transmission

The invention discloses a novel fireproof compensating lead. The novel fireproof compensating lead is composed of a copper conductor, a packing layer, an insulation layer, a wrapping tape layer, aluminum conductors, inner insulation layers and a sheath. The copper conductor is wrapped with the packing layer in an extrusion mode. Three iron wire ropes are evenly arranged in the packing layer in an extrusion mode. The packing layer is wrapped with the insulation layer in an extrusion mode. A plurality of hollow points are arranged inside the insulation layer evenly. The insulation layer is wrapped with the wrapping tape layer in an extrusion mode. A plurality of sets of aluminum cable cores are evenly arranged inside the wrapping tape layer in an extrusion mode. Each aluminum cable core is composed of one aluminum conductor and one inner insulation layer outside the aluminum conductor. The novel fireproof compensating lead is high in tensile strength, good in electromagnetic interference resistance and oxidation resistance and better in dielectric performance. The novel fireproof compensating lead has the good high temperature resistance, aging resistance, inflaming retarding and fireproof performance and the like, has no errors after being used in the high-temperature environment for a long time, and is light in weight.
Description
technical field [0001] The invention relates to the field of cables, in particular to a novel fire-resistant compensating wire. Background technique [0002] At present, thermocouple compensation wires are used for the transmission of thermoelectric effects of thermocouples in industrial and mining enterprises such as electric power, metallurgy, and chemical industry. This wire has excellent electrical properties such as small dielectric constant, small dielectric loss, and large insulation resistance as insulating materials. , so the wire has low capacitance, inductance and stable and good transmission performance. However, with the widespread use of the cable, some problems also appear, such as the requirement for the tensile resistance of the wire is also increasing, and it is connected with the display instrument to form a multi-point temperature measurement system. The insulation and sheath of ordinary compensation wires and other mechanical and physical Performance Un...
