1. Wire surface marking. According to national standards, the surface of the wire shall have a continuous mark of the name of the manufacturer, the type of the product and the rated voltage. This helps to find the manufacturer in time when problems occur during the use of the wire. Consumers must pay attention to this when purchasing wires.
