Wire and cable are materials used for power, electrical and related transmission purposes. Products with few cores, small product diameters and simple structures are usually referred to as wires, those without insulation as bare wires and others as cables.
Wires and cables are everywhere. Here we look together at a few common considerations for wire and cable.
Wire surface markings
According to national standards, the surface of the wire and cable should have the manufacturer's name, product type and rated voltage of the continuous logo.
