Because many circuits are hidden projects, if there are problems or need to be modified, the project is vast and not beautiful. Therefore, it is especially important to select the appropriate circuit before making circuit modifications. The huge difference in the price of wires is due to the different raw materials used in the production process. The main raw materials for producing wires are electrolytic copper, insulating materials and sheathing materials. At present, the Raw Material market has more than 70,000 yuan per ton of electrolytic copper, while the recycled copper is much cheaper; the gap between the quality of the insulating material and sheathing material and the defective product is even more disparate.
So, how to identify the advantages and disadvantages when buying a wire?
Cable can be wire
One must look. See if there is a quality system certification; see whether the certificate is standardized; see if there is a factory name, site, inspection seal, and production date; see if the trademark is printed on the wire, specifications, voltage, etc. Also look at the cross section of the wire copper core, superior product copper color bright, soft color, otherwise it is defective.
The second is to try. It is advisable that a wire head be repeatedly bent by hand, and that any product that has soft hand feeling, good fatigue resistance, plastic or rubber feel elasticity, and no crack on the wire insulation body is superior.
