1. Poor cable production technology. The so-called "no profiteering and no business", although not every Overhead ACSR Cable 336.4 MCM manufacturer is like this, it is inevitable that some businesses in the market do not strictly operate in accordance with standards in the process of producing cables for personal gain. Even some businesses will use some inferior products to make shoddy, resulting in the final production of cables because the quality is not good enough to cause fires during use.
2. The nominal cross-section of the conductor of the cable core does not meet the requirements. Generally, the nominal interface specified is larger than the actual cable produced, and the nominal value of the cable will have a larger unit current density, and the cable will easily cause fire due to the failure of normal heat generation during its operation. accident.
3. Improper transportation. Most of the cables have undergone strict quality inspections before they leave the factory, but they are squeezed and collided due to the lack of correct protection measures during transportation, resulting in damage to the insulation layer or broken internal1-5 Core LV Power Cable.
4. The composition of the insulating material does not meet the requirements or the processing is poor. We know that a material with insulating properties is generally used to wrap the core wire on the outside of the cable. If the quality of the insulating material is unqualified, it will be damaged during use. Will reduce its own withstand voltage performance, and will form unqualified resistance value. In addition, long-term use will shorten its service life, and it is prone to some short-circuit failures and cause fires.
5. The material of the cable is impure or unqualified. The core wire of the cable is generally mainly made of some copper or aluminum conductive materials, and many businesses often use unqualified or insufficient purity materials in the production process, which will cause it to contain more impurities and thus reduce electricity. Therefore, the material used as the core wire must be some high-quality electrolyte materials, generally copper and aluminum.
