Low-smoke halogen-free cable: How to identify a low-smoke halogen-free cable?
What are the identification methods for low-smoke halogen-free cables? 1. Product name identification method for low-smoke halogen-free cables. Low-smoke halogen-free flame-retardant polyethylene insulated wires and cables, low-smoke halogen-free flame-retardant polyethylene insulated, low-smoke halogen-free flame-retardant polyethylene sheathed power cables. Counterfeits generally have slight differences, such as polyethylene insulated low-smoke halogen-free sheathed flame-retardant power cables. 2. Skin burning method for identifying low-smoke halogen-free cables. When ironing the insulation layer with an electric iron, there should be no obvious dents. If there are significant dents, it indicates that there are defects in the materials or processes used for the insulation layer. Or use a lighter to bake, generally should not
What are the identification methods for low-smoke halogen-free cables?
1. Product name identification method for low-smoke halogen-free cables. Low-smoke halogen-free flame-retardant polyethylene insulated wires and cables, low-smoke halogen-free flame-retardant polyethylene insulated, low-smoke halogen-free flame-retardant polyethylene sheathed power cables. Counterfeits generally have slight differences, such as polyethylene insulated low-smoke halogen-free sheathed flame-retardant power cables, etc.
2. Skin burning method for identifying low-smoke halogen-free cables. When ironing the insulation layer with an electric iron, there should be no obvious dents. If there are significant dents, it indicates that the material or process used for the insulation layer has defects. Or use a lighter to bake, generally it should not be easy to ignite. After long-term burning, the cable insulation layer remains relatively intact, without heavy smoke and pungent odor, and the diameter increases. If it is easily ignited, it can be confirmed that the cable insulation layer does not use low-smoke halogen-free materials. If there is heavy smoke, the insulation layer is made of halogen-containing materials. If the insulation surface is severely peeled off, and the diameter does not increase significantly after long-term burning, it indicates that the appropriate irradiation crosslinking process has not been carried out.
3. Hot water immersion method for identifying low-smoke halogen-free cables. Place the core wire or network cable in 90℃ hot water for immersion. Under normal development conditions, the insulation resistance generally will not show a rapid decrease and remain above 0.1MΩ/Km. If the insulation resistance drops rapidly, even below 0.009MΩ/Km, it indicates that the company has not selected and processed a suitable irradiation crosslinking process analysis. (Polyethylene products or cross-linked polyethylene insulation materials are not suitable for identification using this method, and the method in the second item above can be used for risk identification).
4. Density comparison of low-smoke halogen-free cable identification methods.
Hongsheng Wire and Cable Co., Ltd. specializes in the production of power cables, copper core wires, wires, cables, and copper core cables. The product quality is good and guaranteed. Welcome to discuss!
