Refers to a cable with an armored layer of metallic material. The role of the cable plus the armor layer is to enhance the mechanical protection such as tensile strength and compressive strength to extend the service life. Armored cables include armored thermocouples, armored thermal resistors, armored heaters and armored leads, and are mainly used for temperature measurement, signal transmission and special heating in chemical industry, metallurgy, machinery manufacturing, power generation and scientific experiments.
The production of foreign armored cables is mainly concentrated in several relatively developed countries, such as the United States, the United Kingdom, Japan, Germany, and Russia. There are no manufacturers in Southeast Asia, but as long as there are industries such as chemical industry, metallurgy, machinery manufacturing, and power generation, For temperature measurement, armored cables are required.
The armored cable mechanical protection layer can be added to the cable of any structure to increase the mechanical strength of the cable and improve the anti-corrosion ability. It is a wire and cable designed for areas that are vulnerable to mechanical damage and corrosion. It can be laid in any way, and it is more suitable for direct burial laying in rocky areas. Armored cables are generally fixed-laid power cables. Generally speaking, they are fixed in one place and basically do not move, and the power line transmits electric energy.
In addition to the above, the purpose of adding an armor layer to the cable can also enhance mechanical protection such as tensile strength and compressive strength to prolong the service life. The armor has a certain resistance to external forces, and it can also prevent mice from biting, so as not to cause power transmission problems through the armor. The bending radius of the armor should be large, and the armor layer can be grounded to protect the cable.
