Radiation cable FZjv2

Radiation cable FZjv2 is a wire made using radiation cross-linking technology. Radiation cross-linking is the process of using electron beams generated by an electron accelerator to bombard the insulation layer, breaking the molecular chains and forming polymer free radicals. Then, the polymer free radicals recombine and form cross-linking bonds, transforming the original linear molecular structure into a three-dimensional network molecular structure and forming cross-linking.

Radiation cross-linked wire is a new type of home decoration and construction wire produced using this physical method, which makes the wire environmentally friendly, long-lasting, and other characteristics. This product has a large proportion in the construction market and is one of the construction lines.

Characteristics of irradiated cross-linked wires:

It can withstand temperatures of 300 degrees Celsius instantly and work normally at 125 degrees Celsius. Heating the insulation layer with an electric soldering iron should not result in obvious indentations. If there are significant indentations, it indicates that there are defects in the material or process used for the insulation layer. Alternatively, you can barbecue with a lighter. Under normal circumstances, it should not be easy to ignite. After prolonged combustion, the insulation layer of the irradiated cross-linked low smoke halogen-free flame-retardant cable is still relatively intact, without thick smoke or irritating odors, and the diameter has increased. If it is easy to ignite, it can be confirmed that the insulation layer of the cable does not use low smoke and halogen-free materials. If there is a large amount of smoke, it indicates that the insulation layer is made of halogenated materials. If the insulation surface falls off severely after a long period of combustion and the diameter does not increase significantly, it indicates that no appropriate irradiation crosslinking process has been carried out.

Soak in hot water to observe changes in insulation resistance. Soak the wire core or cable in hot water at 90 degrees Celsius, and under normal circumstances, the insulation resistance will not decrease and will remain above 0.1 megaohms/Km. If the insulation resistance drops or even drops below 0.009 megaohms/Km, it indicates that it has not been treated with appropriate radiation cross-linking technology and is not a radiation cross-linked low smoke halogen-free flame-retardant cable. Polyethylene or cross-linked polyethylene insulation materials are not suitable for this method of identification.

Compare density recognition. The density of irradiated cross-linked low smoke halogen-free flame-retardant cable material is higher than that of water, and a small amount of insulation layer can be peeled off and placed in water. If it floats above the water surface, it is definitely not a low smoke halogen-free material.
