Insulation and sheath to judge the quality of UL electronic wires

(1) There should be no adhesion between layers.

(2) The surface is smooth and round, and the luster is symmetrical. There should be no visible lumps, bubbles, burnt objects, etc.

(3) There was no mechanical damage and flattening.

(4) The thickness of insulation (sheath) shall be uniform without deviation from the core.

UL electronic wire

Judging the quality of UL electronic wire from conductor

(1) The color should be even and bright, and there should be no excessive oxidation marks.

(2) The surface should be round and bright, and the coating should be continuous and even.

(3) The size of conductor cross-section should be sufficient without loss of square.

(4) The surface layer of conductor shall not have defects such as triangle mouth, burr, crack, kink, fold, inclusion, scar, pockmark, mechanical damage, corrosion spot, etc.

Judge from other aspects

(3) The filling should be full and the cable should be round.

(1) The shielding layer of metal should be connected, stacked and tightly wrapped, without sharp corners, curling, leakage and other phenomena.

(2) The cable pitch is suitable and uniform.

The above is the UL electronic wire manufacturers from the intuitive judgment of high temperature special UL electronic wire product quality, respectively from the insulation, sheath, conductor and other aspects of discrimination, if you also need to judge the quality of electronic wire brand, you can also try the above several methods.
