Do you think wire and cable are the same type of product? Maybe your answer is "yes", but in fact they are completely different.

Wire and cable are terms that are often used in the electrical and communications fields. However, people often confuse these two terms because they look similar。

The difference between wire and cable


The basic difference between wire and cable is that a wire is a conductor, while a cable is a set of conductors. While these conductors are made of common materials copper or aluminum. Usually, these wires are bare and stranded together. However, some wires are covered with a thin layer of PVC. In the case of cables, they would extend parallel and twist together to form a box. For safety reasons, inner sleeves and jackets are manufactured.


The "wire" in the wire and cable your way


This wire is measured in diameter. Depending on the diameter of the wire, it is measured with the wire gauge number. The smaller the gauge number, the thicker the wire. The ideal size for residential applications is 10 to 20,For example: 10 gauge wire, 14 gauge wire, etc. However, keep in mind that larger wires carry more current and may damage household appliances due to fuse blowing.


The "cable" in the wire and cable your way


The cable consists of a heat-generating wire that carries current, a zero wire to form a loop, and a ground wire. Cables are classified by total number of wires and gauge.

▶▶▶Using Wires

Wires are used to carry electricity, carry mechanical loads, and transmit telecommunication signals to heated jewelry, clothing, automobiles, or any industrially manufactured parts such as pins, bulbs, and needles.

▶▶▶Cables used

Cables are used for electric power transmission, telecommunication signals or power transmission.

Types of wire and cable

▶▶▶The wire

1. solid wire solid wire has only one conductor, is insulated or bare and is usually protected by a colored sheath. This type of wire has a very low resistance and is best used at higher frequencies.

2. Standard wire consists of many thin wires twisted together. These wires are used where flexibility is needed and standard wires can be used for a long time. Conversely, the cross-sectional area of a standard wire is larger than that of a solid wire.

▶▶▶Cable Types

1. twisted pair twisted pair cable consists of 2 pairs of twisted wires. This distortion avoids the noise generated by magnetic coupling and can therefore be used for the transmission of signals. Twisted pair cables are commonly used for data communications and telecommunications.

2. Multi-core cable - Cable has 2 or more insulated conductors and is designed to protect the integrity of the signal. Both twisted pair and multi-core cables are called balanced cables.

3. Coaxial Cable - Coaxial cable has an inner conductor surrounded by parallel outer foil conductors, which are protected by an insulating layer. In the cable, the two conductors are separated from each other by an insulating medium. These cables are usually used for television cables because they are more stable than twisted pair cables.

4. Optical cable - Optical cable transmits signals through a bunch of glass wires. They have a larger bandwidth than metal conductors, which means they can transmit more information and data. Therefore, optical cables are used instead of traditional copper cables.
