At present, there are many types, specifications and models of customized electric wire cable from China on the market. In addition, a variety of fake and inferior cables are rampant. Many customers do not know how to start when selecting customized electric wire cable from China. Choose according to the simple and main level of looking at the sheath of customized electric wire cable from China. Take a look with the Best electric wire cable manufacturers.

Why is it simple? Because the cost of customized electric wire cable from China sheath is relatively low, it is obvious that the quality of wire and cable sheath is not very good, and it depends on the technical and working experience of cable sheath.

1. Pull: high-quality electric wire cable from China insulation layer is not easy to deform and crack when pulled hard.

2. Cutting: Be able to cut a section and carefully observe the cross section of the cable sheath. If there are no bubbles in the white and the filling is inseparable, then you will pass the test.

3. Folding: take out a small section of customized electric wire cable from China and bend it randomly. There is no break or white mark at the bend. The whole wire is smooth and firm.

4. Grinding: the insulating layer is continuously rubbed. If the insulating layer is not damaged and the surface layer is bright, it means that the material is firm.

5. High temperature: put the cable sheath in the sun, and the cable sheath will not fade or melt. It has strong and reliable performance, stable molecular formula at high temperature, and is not easy to dissolve. The high-quality insulation layer can have a variety of resistance.

6.Smoke control: ignite customized electric wire cable from China. The fake and inferior cable sheath will cause many exhaust pipes to emit black smoke, while the high-quality insulation layer only has a small amount of fog. In case of a fire accident, the black smoke from the rich exhaust pipe will block escape. The visibility distance of the high-quality insulation layer reaches 60 meters, further improving the escape probability.

7.Odorless: fake and inferior cable sheath has a choking odor, while high-quality environmental protection insulation layer does not cause a reactive smell and cause choking and escape even under the condition of ignition.
