Wires and cables are the main components connecting electrical appliances and power supply. In order to avoid electric shock accidents, there will be an insulating sheath on the outer layer of the wire, which is often the main reference standard for naming the wire. For example, wdzn is a special kind of wire, but it would be strange if there is no relevant common sense. So, what does wire wdzn mean? What are the classifications of wires and cables? Let's have a brief look with Bian Xiao. \ r \ n \ r \ n \ r \ n \ r \ n \ r \ n \ r \ nIwire wdzn mean \r\n\r\n\r\nw means halogen-free, D means low smoke, Z means flame retardant, and N means flame retardant. \ r \ n \ r \ n \ r \ n \ r \ n \ r \ II. What are the classifications of wires and cables \r\n\r\n\r\n 1, bare wire: this kind of wire is not insulated. \r\n\r\n\r\n2。 Power cable: the main feature is that the metal conductor is protected by insulating layer, which has high safety performance and complicated manufacturing process, including wire drawing, twisting, winding and armoring. According to different types of power cables, the processing technology will be different. \r\n\r\n\r\n\r\n\r\n。 Wires and cables for electrical equipment: There are various specifications and wide uses, especially in circuits below 1kv. In addition, according to the needs of the occasion, a suitable metal wire can be derived from this metal wire. \r\n\r\n\r\n4。 Winding wire: refers to the conductive metal wire used for winding coils or resistors. Because the current will generate a magnetic field when passing through the wire, this kind of wire is also called electromagnetic wire, and generally there will be an insulating layer on the surface. \ r \ n \ r \ n \ r \ n \ r \ n \ r \ Editor's summary: The meaning of wire wdzn and the classification of wire and cable are introduced here, hoping to help you.
