How do buyers intuitively identify the quality of wire and cable ?
In the face of many brands of wire and cable on the market, judging the quality from the appearance is not an easy task. The reason is because of certain characteristics of the cable, not all cables can be known from observation. In general, judging the quality of high-temperature special wire and cable from the appearance is difficult , ( The editor through the consultation of Shenzhen XingGuang electric heating Products Co., LTD.), that we should start from the following aspects .
1、Sheath Insulation
（1）The luster is uniform, the surface is smooth and round, and there should be no visible bumps, bubbles, burnt things, etc.
（2）The insulation (sheath) is uniform in thickness and does not deflect the core.
（3）No mechanical damage and flattening phenomenon.
（4）Various layers of materials should not be adhered to each other.
2、Conductor Structure
（1）The surface of the adhesive layer should be rounded and smooth, and the coating should be continuous and uniform.
（2）The surface of the conductor should not have triangular openings, kinks, folds, inclusions, burrs, cracks, scars, pits, mechanical damage, corrosion spots and other defects.
（3）The appearance is uniform and bright, there should be no traces of excessive oxidation.
（4）The section size of the wire conductor is sufficient, and there is no deficiency phenomenon.
3、Other Aspects
（1）The metal shield layer should be continuous, overlapping, tightly wrapped, without sharp corners, curling, leakage and other phenomena.
（2）The cable pitch is suitable and uniform.
（3）Full filling, round cable.
（4）Wrapping should be overlapping, there should be no curling, omission and other phenomena.
（5）The cable shape should be rounded, no flattening, snake bending and other phenomena.
（6）There should be no traces of moisture inside the cable.
