Guangdong cable manufacturers teach you how to choose qualified wires
Electricity is indispensable in daily life, but if you choose unqualified wire products, it is very easy to cause harm. So, as an ordinary consumer, how should you choose qualified wires and cables? Let’s take BV wire as an example to teach you how to choose wires.
1. Check company qualifications
Before purchasing, you should first understand whether the production company needs to have production qualifications.
2. Check the inspection report
As products that affect the safety of people and property, wires and cables have always been listed as the focus of government supervision and inspection. Therefore, formal and qualified cable products will generally be accompanied by an inspection report issued by the authoritative quality inspection department.
3. Check product labels
The wire certificate of a regular wire and cable manufacturer will contain the factory name, factory address, trademark, product model, specifications, rated voltage, length, production date, implementation standards, etc.
4. Look at the appearance of the product
Qualified wire and cable products should have a smooth, round appearance, uniform color, and several items on the product certificate printed on the surface, with clear writing and not easy to erase.
5. Look at the copper wire. The color of high-quality copper wire is bright and reddish. Inferior copper core wires are generally purple-black, black, yellow or white, have high hardness, many impurities, poor mechanical strength, poor toughness, and will break with a little force.
Finally, when purchasing wires and cables, you must choose a manufacturer with a good reputation, so that the products produced can have quality assurance.
