All high-quality terminal wires are processed through strict testing. In most cases, In most cases, terminal wires are connected together as electrical internal wiring and equipment . We usually rarely touch them, just like our usual refrigerator, We barely touch them. If the quality of the product is too high, the probability of failure is generally very low, so how to judge the terminal wire?
1. The eccentric core cannot appear, and the core wire should be controlled well when it is pressed, otherwise it will cause defects.
2. Observe whether the surface is scratched, variegated, grained, or stained.
3. When cutting wire ends should be aligned flat, and the size should not exceed the tolerance.
4. When the terminal wire penetrates into the plastic shell, whether the color wire sequence is reversed or not in place, etc.
5. Make sure that the terminal wire is inserted into the heat shrinkable sleeve before passing through the plastic shell.
