Irradiated Crosslinked Wires

1. Irradiation Crosslinking Wire is fabricated using irradiation crosslinking process wires, irradiation crosslinking is produced using electron accelerator of high-energy electron beam bombardment insulating layer, will interrupt the formation of polymer molecular chain free radicals, and macromolecular radicals recombination, clinch a deal the cross-links which makes the original linear the molecular structure of the molecular structure into a 3 d mesh and form crosslinking.

2. Irradiated crosslinked wire is a new type of home decoration and construction wire developed and produced by this physical method, which makes the wire have the characteristics of environmental protection, safety, long life and so on. The product occupies a large proportion in the construction market of western countries and is one of the most ideal construction lines in the world.

Characteristics of irradiated crosslinked wires

1. Can instantly withstand 300 degrees, 125 degrees can work normally. Use a soldering iron to iron the insulation layer should not have obvious sag, if there is a larger sag indicates that the insulation layer used by the material or process defects. The insulation layer of Irradiation Cross-Linked Cable Equipment low smoke halogen free flame retardant cable is still relatively complete after a long time of combustion. There is no smoke and irritating smell. At the same time, the diameter has increased. If it is easy to ignite, it is certain that the insulation of the cable is not made of low smoke halogen free material. If there is a large amount of smoke, the insulation layer is using halogen materials. If after prolonged combustion, the insulation surface falls off seriously and the diameter does not increase significantly, it indicates that the appropriate irradiation crosslinking process is not carried out.

2. Soak in hot water to see the change of insulation resistance. Soak the core or cable in hot water at 90 c. Under normal circumstances, the insulation resistance will not drop rapidly and keep above 0.1 megohm /Km. If the insulation resistance drops rapidly or even is lower than 0.009 megohm /Km, it indicates that the irradiated cross-linking process has not been adopted, and it is not irradiated cross-linked low-smoke halogen-free flame-retardant cable. Polyethylene or crosslinked polyethylene insulation shall not be identified by this method.

3. Contrast density identification. Irradiated cross-linked low smoke halogen free flame retardant cable material density than water, you can peel off a little insulation layer into the water, if floating above the water, it is certainly not low smoke halogen free material.
