Purchase Knowledge of Home Application Wire and Cable

Wire surface marks according to the national standard, there should be factory name, product model and continuous symbol of rated voltage on the wire surface. This is good to use the electric wire when problems occur in the process, you can find the manufacturing factory in time, it is important for consumers to note this when choose and buy wire. At the same time, when purchase wire, consumers should pay attention to if the indicated on the certificate of manufacturer name, product model, rated voltage are consistent with printing marks on the surface of the wire, to prevent counterfeit products.
