1. Product identification.When purchasing wire and cable products, you should observe whether the product's certificate of conformity is fully marked with relevant information such as product model, specification, rated voltage, number of cores, production date, implementation standard, license number, etc., and the physical surface of the product should be printed with the continuity mark of the factory name, product model and rated voltage to verify whether the relevant information of the two is consistent.；

2. Appearance and material.The outer plastic skin of the wire is bright in color and fine in texture, whether there are burrs or protrusions on the surface, whether the appearance is smooth, round, and uniform in color, the conductor uses electrolytic copper, and the outer layer is bright and slightly soft.Take a look at the cross-section of the cable again. The copper core should be in the middle, and the thickness of the plastic layer should be uniform.；

3. Length and cross section.There is a length mark on the certificate of conformity. You can first estimate the length of a circle of wire in the finished product packaging, and then count the number of turns of the reel to estimate the approximate length of the entire reel. In addition, pay attention to the diameter of the conductor and look at the length and cross-section of the cable.；

4. When choosing wire and cable products, zui should consult an experienced professional electrician to adopt a cable of suitable cross-section size and voltage level according to his own electrical load.

As the main carrier of power transmission, wire and cable products are widely used in electrical equipment, lighting circuits, household appliances, etc., and their quality directly affects the quality of the project and the safety of consumers' lives and property.Consumers must pay attention to the four major points of “three more” in order to use safe and secure cables.
