First, what is flame retardant cable: flame retardant cable refers to the cable that under specified test conditions, the sample is burned, and after removing the test fire source, the spread of the flame is only within a limited range, and the residual flame or residual burn can extinguish itself within a limited time. The basic characteristics are: in the case of fire, it may be burned out and cannot run, but it can prevent the spread of the fire. Generally speaking, in case of fire, the wire can limit the combustion to a local scope, keep other various equipment, to avoid greater losses.

Second, the difference between flame retardant line and ordinary line

The difference between ordinary insulated wire and flame retardant wire is that flame retardant wire has passed flame retardant test or certification and ordinary cable has not. Most of the ordinary insulated wires and flame retardant wires are not much different in appearance, but the domestic flame retardant wires will add ZR words to the printing content. If the ordinary line and the flame retardant line are connected in series and the current is increased at the same time, we can clearly see that the ordinary line produces a lot of smoke and has a pungent smell, while the flame retardant line is not damaged."

Third, is it necessary to use flame retardant line in home decoration?

In recent years, in the global power system fire accidents, the disaster of power supply interruption caused by cable occurred and showed an increasing trend. Therefore, it is increasingly important for us to use flame retardant wires in home decoration to prevent the spread of fire.

Home improvement wire or to use flame retardant, flame retardant wire in the accidentally fire when compared to ordinary wire it can minimize the loss of the home, external purchase of flame retardant wire must look for the cable with ZR logo, do not believe the three no products, wire is a hidden project early processing is not good behind there will be a lot of trouble waiting.

Home improvement wire purchase details

1, when buying wire, look for the CCC certification mark to prove whether the product is qualified. The product certificate will also be printed with the trademark, length, model specifications, rated voltage and other information of the wire to see whether the information printed above is consistent with the product.

2, the quality of the wire can also be seen from the appearance, take a wire head repeatedly bent by hand, if the feel is soft, good fatigue strength, rubber elasticity, not easy to crack, you can buy; You can also use your nails to scratch on the insulation layer, if you can leave a scratch, it proves that the insulation layer is poor in elasticity.

3, strip the insulation layer of the wire to see the color of the copper core conductor, high-quality copper core wire should be purple, shiny, soft texture, on the contrary, it is relatively dim, and may contain too much impurities.

4. Burn the insulation layer with a lighter until it is removed after the fire, and calculate the extinguishing time of the insulation layer. Automatically extinguished within 5 seconds, proving that the flame retardant performance of the insulation layer is up to standard; If the automatic extinguishing time is longer, or even the more burning, the flame retardant is too poor.

Qingdao Tianxing Cable Co., Ltd. focuses on the production of customized wire and cable manufacturers, main: fire wire and cable, power cable, control cable and other products, exported to more than 40 countries and regions around the world, the annual production capacity of 1 billion yuan. 6000 square meters of storage, standing hundreds of millions of inventory, order demand for rapid distribution and delivery, large prices more favorable.
