Electric wires, as a rigidly needed product for home or office decoration, have a huge market space. With the increase of environmental awareness, more and more people have begun to choose low-smoke ul halogen-free electronic wire fire-resistant electric wires, but low-smoke halogen-free fire-resistant electric wires are actually much more sophisticated.

When selecting wires, choose fire-resistant wires with low-smoke ul halogen-free electronic wire irradiation cross-linking technology, which is more secure and reliable.

What are the advantages of low-smoke halogen-free radiation crosslinking technology?

First of all, we must know that the halogen-free electronic wire and cable materials for low-smoke ul are made of polyolefin halogen-free materials, such as polyethylene, cross-linked polyethylene, and radiation-crosslinked polyethylene. If the traditional warm water cross-linking technology is used, the quality of the wire will become unstable due to factors such as water temperature, extrusion process, and cross-linking additives. The quality of the irradiated cross-linked cable depends on the radiation dose of the electron beam. Dosage is achieved through the setting of special equipment parameters, and the processing stability is good.

The transmission capacity and short-term overload capacity of irradiated cross-linked polyethylene are much higher. At the same time, the heat resistance, insulation, chemical resistance, aging resistance and mechanical strength of the material have been greatly improved.

How to identify whether low smoke ul halogen-free electron wire irradiation cross-linking technology is used?

1. Epidermal scalding method

Hot the insulation layer with an electric iron, there should be no obvious depression, or grill with a lighter, it should not be easy to ignite under normal circumstances, the insulation layer of the cable is still intact after long-term burning, without heavy smoke and irritating odor, and The diameter has increased.

2. Contrast density

The density of the radiation-crosslinked low-smoke halogen-free flame-retardant cable is greater than that of water. You can peel off a little insulation layer and put it in water. If it floats above the water surface, it is definitely not a low-smoke halogen-free material.
