The wire harness belongs to the weak electric cable, which is the internal connecting wire of the electrical equipment. At present, the main wire harness on the market mainly includes UL standards.
The wire harness is used for the connection inside the appliance, so its conductive function is very important. If the current of the wire harness is unstable, it will cause the unstable performance of the appliance. Therefore, this must be taken care of when purchasing. Let’s take a look at what the high-quality wire harness is like:
1. Smooth surface, no black line, no chaotic line, no pitting, no oxidation, no smudge, no scratches, no tin plating (sticky tin, leaking tin), no slash, no hand joint, No fingerprints.
2. The surface of the copper wire is not sticky after the terminal wire is rolled (overfilled)
3. The tension of the terminal wire is moderate but loose or too tight.
4, the wire harness is good, uniform, no stacking, underside (low side of the side or low side of the two sides), no stocks.
