We often use wires and cables, but how do we choose good quality wires and cables? There are many tips in this. If you master them, you can avoid the trouble caused by wires and cables. There are countless large and small wire and cable manufacturers, and there are also many manufacturers for us to choose from. The price, quality, and service of wires and cables in these manufacturers are different. Therefore, when purchasing wires and cables, we need to pay attention to these tips that are often used in life.

1. Learn to look at the packaging. National standard wires and cables will have uniform packaging, smooth and neat surface.
2. Look at the information on the packaging, which usually includes trademarks, manufacturer names, specifications, models, implementation standards and other information. You should carefully check whether this information is available. If not, ask for clarification.
3. Touch the outer protective sheath (PVC sheath) of the wire and cable with your hand. If it feels a lot of bumps, it means that the workmanship is very rough and it is not recommended to buy it. We can also burn the outer skin with fire. If a small amount of smoke is emitted after burning and it automatically extinguishes within 5 seconds after leaving the fire, the wire and cable are national standard wire and cable with flame retardant function.
4. Look at the internal copper core of the wire and cable. The surface of the copper core is shiny, the brightness is uniform, and it looks like there is no layering, which means it is good quality copper. National standard wires and cables use oxygen-free pure copper, and non-standard wires and cables may not use such good copper materials.

Choosing good quality wires and cables involves careful consideration of materials, specifications, construction, and certifications. By understanding your requirements and evaluating the quality of the products, you can ensure reliable and efficient performance in your electrical systems. Prioritizing safety, performance, and durability will contribute to the longevity and effectiveness of your installations.
