Don’t look at the brand to check the quality, use a small method of burning to test:

1. Burn with a lighter to see if there is an open flame. If there is an open flame, the flame retardancy is not good;

2. Is there any peculiar smell after burning? If so, then the outer material is not good;

3. If the outer skin is black, if it is black, then the material is not good;

4. Check whether the copper core is black. If it is black, it is not oxygen-free copper and has poor oxidation resistance.
