What is the differences between a wire and a cable?

How to distinguish is a wire or a cable?
Wires are generally used as conductive metal wires that carry current and come in various forms such as solid, stranded or foil braided. According to the insulation status, it is divided into two categories: bare wire and insulated wire.
A cable is an insulated wire composed of one or more mutually insulated conductive cores placed in a sealed sheath. A protective cover can be added to it for transmission, distribution of electrical energy or transmission of electrical signals. The main difference between it and ordinary wires is that the cable size is larger and the structure is more complicated.

It is generally believed that a single one is called a wire; a plurality of it is called a cable.
The smaller diameter is called the wire; the larger diameter is called the cable.
simple structures called wires
all Yihetai Cable wire and cables are using for Industrial, Automation, Medical, Automotive, Consumer Electronics, New Energy, etc.


There are 5 main differences:
1. Differences in use: Bare wires are not covered with any insulation or protective layer. In addition to being used as wires for transmitting electrical energy and information, they can also be used to manufacture components and connecting wires of motors and electrical appliances. There are also various insulated wires suitable for special requirements, such as low-voltage wires for automobiles, high-voltage ignition wires for automobiles, lead wires for electric motors, aviation wires, compensation wires, etc. Cables are used to transmit, distribute electrical energy or transmit electrical signals, and are mostly used in densely populated and grid-dense areas and places with heavy traffic.

2. Material structure: The wires are mostly composed of soft wires with a relatively soft protective layer on the outside. Compared with the conductor of the cable, which is wrapped by insulation, the insulation of the cable is usually thicker. According to different laying requirements, the insulation layer of the cable also includes a metal armor layer.


3. Product structure: The size of the wire is much smaller than that of the cable, and the structure of the wire is relatively simple.



4. Current and voltage: The wire is mainly a line with a small transmission voltage; while the cable is mainly a power line with a relatively large transmission voltage, and the applicable current and voltage levels are different, which is a particularly obvious difference.
5. Structural hardness: The voltage and current transmitted by the wire are not as large as those of the cable. In a certain respect, the structural hardness of the wire is not as strong as that of the cable.

Wire: The general structure is relatively simple, such as BV wire, called cloth wire.
Cable: The general structure is more complicated, such as YJV, called copper core XLPE insulated PVC sheathed cable, but this difference is not absolute, such as BVV, called cloth wire, the structure is PVC insulated PVC sheathed ; And VV, called cable, the structure is PVC insulated PVC sheath. The only difference between the two is the voltage level. Therefore, there is no strict distinction between wires and cables, but some conventional names in the industry.
