Today, Qingdao power cable manufacturers to introduce you, what are the causes of the fire?

1. The nominal section of conductor of the power cable core wire does not meet the requirements. Generally, the nominal interface is larger than the actual production of the cable, and the nominal value is biased to the standard cable will have a larger unit current density, and the cable is easy to cause a fire accident during its operation because it cannot normally generate heat.

2, power cable production process is poor. Although not every manufacturer is like this, there will inevitably be some businesses on the market in order to seek personal gain, and they do not strictly operate according to standards in the process of producing cables. Even some businesses will use some poor quality products, resulting in the final production of cables because of poor quality in the use of fire.

3, the material of power cable is not pure or unqualified. The core wire of the cable is generally made of some conductive materials of copper or aluminum, and many businesses often use unqualified or not pure enough materials in the production process, which will lead to a decrease in power because it contains more impurities. Therefore, the material used as the core wire must be some high-quality electrolyte materials, generally mainly copper and aluminum.

4, the insulation material composition does not meet the requirements or poor processing, we know that the outside of the power cable is generally selected a kind of insulating material to wrap the core wire, if the quality of this insulating material is not qualified, it will reduce its voltage performance during use, and will constitute unqualified resistance value. In addition, long-term use will also shorten its service life, it is easy to appear some short circuit fault caused by fire.

5. Improper transportation. Most power cables have passed strict quality inspection before leaving the factory, but they are kneaded and collided during transportation because there are no correct protective measures, which causes the insulation layer to be damaged or the internal core wire to be broken.

Qingdao Tianxing Cable Co., Ltd. focus on supporting wire and cable production customization manufacturers, main: exports 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.
