How to choose wires and cables

There are many fake or poor quality products on the market, and wires and cables are particularly important in life, especially in terms of safety. So how do we prevent defective products from being bought? JZD wire and cable tells everyone that the copper content of the core should be high, and the surface color should be bright. After cutting, the core and the surface have the same color. Next we will look at it in detail.

1. Select the core conductor material of wire and cable. In the current market, the conductor materials that can be used for wire and cable are basically copper, copper-clad copper, copper-clad aluminum and aluminum. The performance ranking of these materials is as follows:

                                                       Copper＞Copper Clad Copper＞Copper Clad Aluminum＞Aluminum

Copper-clad copper refers to impure copper, which is doped with other metal elements.

Copper clad aluminum refers to a layer of copper coated on the outside of the aluminum wire.

When buying, you must pay attention to explain your needs to the seller, and at the same time avoid the seller from shoddy.    

2. Look at the insulation on the outer layer of the wire and cable

The good quality cables has a smooth appearance, clear handwriting, uniform color, and it is not easy to pinch it with a nail. However, the outer insulation of inferior cables is not lubricated and has small protrusions. The handwriting on it is fuzzy and unclear, and the colors are not common. The outer insulation can be easily pinched off with a nail.

Wires and cables are common items in life, and safety is very important. We must ensure the high quality of wires and cables, and at the same time prevent the sale of inferior products. At the same time, we warn you not to be cheap, inferior wires and cables will cause serious consequences such as fires and electric shocks. To ensure your safety, please purchase high-quality wires and cables.
