Low smoke halogen free flame retardant cable

2020/01/07

What are the characteristics and identification methods of low smoke halogen-free flame retardant wires?We don't know anything about low-smoke halogen-free flame retardant wires, many people only know about wires, but we know little about wires of different USES, so if we want to know low-smoke halogen-free flame retardant wires, we have to know the characteristics of low-smoke halogen-free flame retardant wires and what is the identification method?The specific knowledge of the goldwater cable arrangement is as follows:

What are the characteristics of low smoke halogen free flame retardant wires?

Each kind of wire has a different purpose, that is because it has the characteristics that other wires do not have, so before we buy low-smoke halogen-free flame retardant wire or to understand the characteristics of low-smoke halogen-free flame retardant wire is what it is.

1. Characteristics of low-smoke halogen-free flame retardant wires -- tensile strength is higher than that of ordinary PVC wires: tensile strength of ordinary PVC wires is greater than 1.05Kgf/mm2, while tensile strength of low-smoke halogen-free wires is greater than 1.2Kgf/mm2;

2. Characteristics of low-smoke halogen-free flame retardant wire -- good weather resistance (-30℃~105℃);Good softness (hardness 80-90);

3. Characteristics of low-smoke halogen-free flame retardant wire -- non-shifting (because plasticizer is not added in the formula of this product, there will be no shifting);Burning does not produce toxic black smoke (a small amount of white smoke);Have high volume resistivity: PVC wire is commonly 1012 ~ 1015 Ω/cm3, low smoke zero halogen wire is greater than 1016 Ω/cm3;(7) good high voltage resistance: PVC wires are generally resistant to more than 10KV, while low-smoke halogen-free wires are generally resistant to more than 15KV;(8) good elasticity and viscosity.           

What is the identification method of low smoke halogen free flame retardant wire?

1. Product name identification method for identifying low-smoke halogen-free flame retardant wires.Wires -- low smoke halogen-free flame retardant polyethylene insulated wires and cables;Cables - low smoke halogen-free flame retardant polyethylene insulated low smoke halogen-free flame retardant polyethylene sheathed power cables.The name of the imitator is usually a little different, such as polyethylene insulated, low-smoke, halogen-free sheathed, flame retardant power cable, etc.

2, low smoke halogen-free flame retardant wire identification method of the skin burning method.Hot with an electric iron insulation layer should not have obvious sag, if there is a large sag indicates that the material or process used in the insulation layer is defective.Or use lighter barbecue, under normal circumstances should be not easy to ignite, long burning after the insulation layer of the cable is still relatively complete, no smoke and irritating smell, at the same time increased in diameter.If it ignites easily, it can be determined that the insulation of the cable is not made of a low-smoke halogen material (probably polyethylene or crosslinked polyethylene).If there is a large amount of smoke, the insulation layer is halogenated material.If the insulation surface falls off seriously and the diameter does not increase significantly after a long time of combustion, it indicates that appropriate irradiation crosslinking process has not been conducted.

3. Identification method of low-smoke halogen-free flame retardant wires by hot water immersion.Put the core wire or cable in 90 ℃ hot water immersion, insulation resistance will not normally fell sharply and keep above 0.1 M Ω/Km.Ω such as insulation resistance fell sharply even less than 0.009 M/Km, then without proper irradiation crosslinking process.(polyethylene or crosslinked polyethylene insulation material is not applicable to this method of identification, can be identified by the method in article 2 above).
