First, what is an irradiated cable?
1. The irradiation cable strikes high-energy molecules on the insulation layer of the wire through the transmission of the electron accelerator, so as to change the original molecular structure. The chain structure becomes a three-dimensional network structure, which causes great changes in the performance of the insulation layer, and the mechanical and chemical properties are greatly improved.
2, in fact, irradiation is a kind of processing, low smoke halogen-free is a kind of material characteristics, irradiation is generally the polyethylene material into a cross-linked polyethylene processing process, belongs to the physical method, energy saving and environmental protection, high efficiency, good control, low smoke halogen-free material is in line with certain indicators, low smoke halogen-free cable should comply with GB/T.
Second, the difference between irradiated cable and ordinary cable
1. The difference in weight
Compared with ordinary cables, irradiated cables have light weight, which is not only convenient for installation and transportation, but also can reduce the labor intensity and transportation cost of installation personnel. At the same time, large pipe diameter can be used for threading in the installation process, so as to reduce the total cost of installation.
2, the difference in heat resistance
The irradiated cable has strong heat resistance and can reach higher temperature during operation. At the same time, the irradiated cable will not release toxic gas when burning, and will not cause secondary harm to the air and environment, which meets the modern fire safety standards. In addition, it also has good electrical properties, in the process of use is not susceptible to temperature. Therefore, it is used as a new product with high environmental protection and safety in modern fields.
3, the difference between mechanical and physical properties
Compared with other materials, high quality irradiated cables have good mechanical properties, wear resistance and mechanical stress than other types of materials. However, irradiated wires are stable in media around various chemical solvents.
Finally, what does the irradiating cable do？
1. Irradiation cable refers to the irradiation processing of wires and cables. Under the irradiation of high-energy electron beam, cross-linking covalent bonds are formed between the insulating layer and the polymer material of the sheath layer of wires and cables, and the network or body structure is generated, which is also called irradiation cross-linking.
2, irradiation cable play what role, after irradiation crosslinking modified wire and cable strength, elasticity, hardness has been improved, solvent resistance, environmental stress cracking resistance has also been greatly improved, the most important is heat resistance and short-circuit resistance temperature has been significantly improved.
