Zhengzhou Wubai Cable and Wire Co.,Ltd

As we all know, an ordinary photovoltaic cable has a very wide range of uses, and its quality is directly related to the safety of life and property of thousands of households. If you accidentally use counterfeit and shoddy non-standard wires, serious safety hazards will be buried in the future. As such, it will cause short circuits, electric shocks, and economic losses; in serious cases, it will cause fire and endanger life and safety, so you must use quality assurance. National standard products.

1. First, you need to carefully look at the label printing, handwriting and address of the cable. If there are typos or different printing depths, then you must pay attention to the content of the text above. If it is produced by a regular cable manufacturer, the cable, The label on top of it is clear, so it's worth noting.

2. If there is discoloration or missing characters on the cable, then you can tighten the insulation of the cable by hand. Usually low-quality cables, as long as you twist the insulated wire by hand, it will easily fade, especially the low-quality cables. The red line is the most obvious.

3. Bend the insulated wire repeatedly by hand, and bend it back and forth three or four times. If it breaks, it means that the wire is definitely inferior. It should be clear that the insulation layer of the inferior wire is generally of poor material, so bend it back and forth for 3 After ~4 times, the insulating layer will naturally break.

Points to note:

Ignite the insulating layer of the photovoltaic cable with fire, keep away from the open flame and the wire spontaneously ignites. We can take a few wire ends for experiments. After igniting the insulating layer and leaving the open flame, it will spontaneously ignite. This is also a detection method for inferior wires. Practice is the only standard for testing the truth. Practice is the last word. In recent years, there have been more and more fire accidents caused by unqualified cables. Many people have purchased unqualified products because of their lack of understanding of cable knowledge. The production and purchase of national standard wires is the responsibility of each of us. Duties and responsibilities to ensure the security of electricity supply and the healthy development of the wire market.
