Why Is A High-flex Cable Prone To Fire Accidents?

Nov. 02, 2018

High-flexible cables are now used more and more widely, but with its popularity in the national power supply lines, some of its security issues have gradually attracted people's attention, especially in recent years. It is a reminder that people should pay special attention when using this cable. So, what are the quality reasons for fire accidents caused by high-flex cables? Let's take a look at it!

1. The nominal cross section of the conductor of the cable core wire does not meet the requirements. Generally, the nominal interface is larger than the actual cable produced, and the cable with a nominal value biased to the standard will have a larger cell current density. During its operation, the cable is prone to fire due to the inability to generate heat normally. accident.

2. The cable production process is poor. The so-called non-profit and non-business, although not every manufacturer, but in the market, there will inevitably be some businesses in order to seek personal gains, in the process of producing cables, do not strictly follow the standard. Even some merchants will use some inferior products to make them indiscriminate, resulting in the final production of the cable because the quality is not related to the fire during use.

3. The material of the 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 merchants often use materials that are not qualified or of insufficient purity in the production process, which causes them to be reduced because they contain more impurities. electric power. 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 cable is generally a material with insulating properties to wrap the core wire, if the quality of this insulation material is not qualified, it is in use Will reduce its own pressure resistance, and will form an unacceptable resistance value. In addition, long-term use will shorten its service life, and it is easy to cause some short-circuit faults to cause fire.
