Decorate new home now leave the water and electricity transformation, good need to use a variety of wire, today we talk about how to distinguish authenticity weak wire? Weak wire and how to distinguish authenticity?
The cross section is a good way to distinguish the wire. Weak wire depends on several points include:
1, the copper thickness
2, purity,
On the market most cheap cables is made with brass or (copper clad aluminum) conductor, brass disclose is copper and zinc alloy, hardness is better, but not conductive, the authentic high purity oxygen free copper cable application, very soft, is an excellent raw material for high quality low voltage wire.
3, the close degree of tin foil package
4, shielding net four layer (layer tinfoil + 2 aluminium magnesium wire woven mesh)
5, skin strong degree
6, then look at wire outer plastic skin should be bright color, fine texture.
Informal use recycled plastic products, colour and lustre is dim, loose texture, can ignite fire.
After all, is to see a material and workmanship, fake goods is fake, impossible as authentic craft, so check the process carefully, will find many clues. Best can tear the wire, so that can see more clearly.
Common weak wire include: high-definition television line, network line, telephone line, audio line, AV line, VGA line, audio line, and so on.
The authenticity of weak wire resolution and strong wire method is similar, actually the first to look at the plastic texture of skin. Push the wire after folding the restorable, inferior wire leaves cannot disappear crease, is very obvious, while high quality wire won't have this kind of phenomenon.
