Irradiated cross-linked wires are wire products processed using special processes. These wires have been very popular among users since their development and production. They are a new type of home decoration construction wire with advantages such as environmental protection, safety, and long service life. Especially in the construction market of Western countries, they occupy a large proportion and are an ideal type of wire for indoor decoration.
Irradiation cross-linking wire is made by irradiation cross-linking process. Irradiation cross-linking is to use high-energy electron beam generated by electron accelerator to bombard the insulation layer, break the molecular chain to form polymer free radicals, and then reassemble the polymer free radicals to form bonds, so that the original linear molecular structure becomes three-dimensional network molecular structure to form cross-linking.
Advantages of irradiated cross-linked wires:
(1) It has excellent mechanical and physical properties, good resistance to environmental stress cracking, excellent wear resistance, and can withstand concentrated mechanical stress better than PVC and PE.
(2) Resistant to various chemical solvents and relatively stable in various corrosive media around.
(3) The outer diameter of irradiated cross-linked polyolefin insulated wires is smaller than that of fully polyvinyl chloride insulated wires of the same specification section. It can reduce the use of pipe diameters in pipe laying construction, or wear more wires under the same pipe diameter conditions, reducing construction and installation costs.
(4) The weight of irradiated cross-linked polyolefin insulated wire products is much lighter than that of PVC insulated wire products, which is more convenient for installation and transportation, reduces labor intensity, and reduces transportation costs.
(5) The maximum rated temperature of irradiated cross-linked insulated wires during long-term operation can reach 125 ℃, and the current carrying capacity is greater than that of PVC insulated wires.
(6) It does not release corrosive or toxic gases during combustion and does not cause secondary hazards. It meets modern fire safety requirements and is a new type of environmentally friendly product.
(7) Good electrical performance, much higher insulation resistance compared to PVC wires (cables), and tangent value of dielectric loss angle tan δ Very small, basically not changing with temperature changes
Introduction to relevant models:
BYJ/RYJ copper core cross-linked polyethylene insulated hard/soft cloth wire 450/750V 1.5-185mm2; WDZR-BYJ/RYJ copper core flame-retardant halogen-free low smoke cross-linked polyethylene insulated hard/soft fabric wire 450/750V 1 1.5-185mm2; Usage: BYJ cross-linked wires are suitable for fixed wiring of power devices such as buildings, electrical appliances, switches, etc. with a rated voltage of 450/750V and below.
