How To See Quality Of Electric Wire Cable Stand Or Fall

Cable Detection Equipment Supplier tells you that wire and cable as the main carrier of power transmission, widely used in electrical equipment, lighting lines, household appliances, etc.

1. product identification. Wire and cable products should be observed when the choose and buy the quality certificate for the product models, specifications, rated voltage, some conclusions, production date, executive standard, whether the license number and other relevant information tagging is complete, the product surface should be printed with name, product model and the continuity of the rated voltage, verify the relevant information whether are the same.

2.Appearance and material. Electric wire outer plastic skin colour and lustre is bright, quality of a material is close, whether the surface has burr or prolate, the exterior is smooth, round, colour and lustre is even, conductor USES electrolytic copper, outer brightness and a bit soft. If you look at the cross section of the cable, the copper (aluminum) core should be in the middle, and the thickness of the plastic layer should be even.

3.Length and section. There are length marks on the qualification certificate, you can first estimate the length of a coil of wire in the finished product packaging, and then count the winding number of the wire coil to estimate the approximate length of the whole coil of wire, in addition to pay attention to the diameter of the conductor, see the length and section of the cable.

4. Choose wire and cable products, it is best to consult experienced professional electrician, according to their own load to use the appropriate section size and voltage level of the cable.

5. In order to ensure the normal use of cables and wires, regular testing is carried out with the aid of Cable Detection Equipment.
