First, look at the quality certificate of home appliances
If the quality of the home appliance is qualified, then the quality of the power cord of the home appliance should also be tested, and there will be no major problems.
2. Check the cross-section of the wire
The cross-section of the wire, the surface of the copper core, or the aluminum core of the qualified product should have a metallic luster, and the copper or aluminum with a white surface has been oxidized, which is a non-qualified product.
3. Look at the appearance of the power cord
The insulating (sheath) layer of qualified products is soft, tough, and stretchable, and the surface layer is tight, smooth, without roughness, and has pure gloss. The surface of the insulating (sheath) layer should have clear and scratch-resistant marks. Products produced from informal insulating materials have a transparent, brittle, and inflexible insulating layer.
4, look at the core of the power cord
The wire core is produced by using pure copper raw materials and has undergone strict wire drawing, annealing, and twisting.
5. Look at the length of the power cord
Different electrical appliances require different lengths of power cords. Decoration owners should know the length of qualified power cords before purchasing, so that they can be aware of when purchasing electrical appliances.
In order to ensure the normal use and living safety of home appliances, decoration owners must pay attention to the selection of power cords and carefully check their quality when purchasing home appliances. Trouble yourself.
