- The difference between wires and cables
Wires are generally used as conductive metal wires that carry current. There are various forms such as solid, twisted or foil braided. According to the insulation condition, they are divided into two categories: bare wires and insulated wires.
Cables are insulated wires composed of one or more mutually insulated conductive cores placed in a sealed sheath. A protective covering layer can be added to the outside to transmit, distribute electrical energy or transmit electrical signals. The main difference between it and ordinary wires is that the cable is larger in size and has a more complex structure.
The difference between wires and cables is that wires are generally smaller in size and simpler in structure, but cables are sometimes included in the broad sense of wires.
- The difference between wires and cables and wiring harnesses
1）Wires and cables are wire products used to transmit electromagnetic energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables, which can be defined as: a collection of the following parts: one or more insulated wire cores, and their respective coatings, total protective layers and outer sheaths. Cables may also have additional uninsulated conductors.
2）The wiring harness is the overall service equipment for a certain load source group, such as relay lines, switching devices, control systems, etc. The basic research content of traffic theory is to study the relationship between traffic volume, call loss and wiring harness capacity. Therefore, the wiring harness is an important basic concept in traffic theory. The load source is the service object of the wiring harness, usually referring to the user equipment. In a broad sense, the upper-level equipment is the load source of the lower-level equipment. Any load source that makes a call can occupy an idle service device in the wiring harness.
