Electrical wire and cable comes in a variety of types and sizes and in order to put a particular types in to right uses we need to know what types and what sizes are available. The term "wire" refers to a single metal rod that has a relatively modest diameter in comparison to its whole length. A piece of metal that is not insulated and can be used to convey current is referred to as a conductor. There are two distinct varieties of conductors, which are referred to respectively as solid conductors and stranded conductors. 
A stranded wire is made up of multiple smaller solid strands strung together. These individual wires are twisted together to create a stranded conductor that is more flexible. As an illustration, a cable might be referred to as 7/36 wire in 26 AWG. The conductors are made up of seven strands of wire with a gauge of 36, and these strands are all twisted together to form a conductor with a gauge of 28. A single conductor or a collection of conductors that are insulated from one another make up a cable. Cables can also be called wires (multi-core cable ). Why it's crucial to use the right cable size in your wiring A conductor in a cable is only able to carry a certain amount of voltage before it becomes dangerous. The structure of the cable will eventually start to deteriorate if the current that is flowing through the cable is greater than the limits of the particular conductor that it is using. 
Each cable or insulated conductor has what is known as an ampacity, which is also referred to as the ampacity. Certain sizes increase the diameter or cross-section of the cable, which lowers the cable's resistance and increases its capacity to transmit current.
power cable types size
In every scenario, determining the appropriate power cable size and types is one of the most crucial considerations. Because there are so many different kinds of conductors, insulation materials, voltage classes, and conductor sizes, it can be very challenging to locate the answer that's suitable for you. Why it's crucial to use the right cable size in your wiring A conductor in a cable is only able to carry a certain amount of voltage before it becomes dangerous. The structure of the cable will eventually start to deteriorate if the current that is flowing through the cable is greater than the limits of the particular conductor that it is using. 
There is an ampacity rating assigned to each cable or insulated conductor. Certain sizes increase the diameter or cross-section of the cable, which decreases the cable's resistance and increases its capacity to carry a current. Constraints Placed on the Choice of Cable Size Wires and cables have defined sizes. People often use larger or smaller wires than needed. The versatility of the terminals makes this possible. This may limit your possibilities.There are a number of benefits to utilizing wire and cable. Wire: The use of solid wire, which has low resistance and works well at high frequencies, is recommended. Cables: Cables are built with great strength and strong insulation, making them perfect for use in applications that require heavy duty because of their construction. 
Norms that are applicable to both: Wires and cables that are not securely fastened should not be placed in areas where they could cause someone to trip. Wires and cables that are damaged need to be replaced. Polarization and safety closures are two important features that should be included on all wires and cables.
types of cables
The distinction between types of wires and cables is not particularly clear-cut. Products that have a small number of cores, a small product diameter, and a simple structure are typically referred to as wires. Products that lack insulation are referred to as bare wires, and other products are referred to as cables. Products that have a larger conductor cross-sectional area (greater than 6 square millimeters) are referred to as large wires. Wires that are considered to be little if their area is six square millimeters or less are referred to as small wires, whereas insulated wires are also referred to as fabric wires. The following are the primary categories that are utilized to classify wire and cable products: 
(1) Bare wires and other things that are bare conductors These goods have a pure conductor metal and no insulation or sheathing. Steel-cored aluminum stranded wires, copper-aluminum busbars, and electric locomotive cables are examples. (2) An electrical cable Extruding (winding) the insulating layer on the outside of the conductor, as in overhead insulated cable, or twisting with many cores are the primary characteristics of this type of product. Other characteristics include: (corresponding to the phase wire, neutral wire and ground wire of the power system) Large currents (ranging from tens of amps to several thousand amps) and high voltages are two characteristics that characterize the transmission of powerful electric energy in power generation, distribution, transmission, transformation, and power supply lines. This is the primary application for the products (220V to 500kV and above). 
(3) Wire and cable for use with various electrical devices The usage of voltages of one thousand volts (kV) or less is one of the primary characteristics of this category of products, along with the fact that they are available in a wide range of specifications and applications.
electrical wire types chart
The naming conventions chart for various wire and cable product types is the basis of any kind of later references so it behooves everyone to ensure a comprehensive understanding of the details of cable and wire naming. The following is a list of the most common names for wire and cable products: (1) The name of the product's application or size class (2) Product composition in terms of either material or kind (3) Essential characteristics of the product, in addition to any available characteristics 
The names are arranged in this order for the most part; but, in some cases, in order to place emphasis on particularly noteworthy or relevant characteristics, characteristics are sometimes placed before or before the matching structural description. Beginning from the inside and working your way out, as the saying goes, is the general premise of product structure description: conductor, followed by insulation, then inner sheath, then outer sheath, and finally armor type. The following is a model of the makeup of the power wires and their order: Make use of manganese in the following categories: Conductor; Insulation; Inner Sheath; Structural Features; Outer Sheath or Derivative; Category; (1) Cable category ZR (flame retardant), NH (fire resistant), DDZ (low smoke and low halogen), WDZ (low smoke and halogen free), K (control cables), DJ (computer), N (agricultural direct burial), JK (overhead) Cables), B (clothed wires), TH (for hot and humid areas), FY- (termite prevention, enterprise standard), etc. are a few of the many different types of wires available. 
(2) The conductors of the cable T (copper conductor), L (aluminum conductor), G (steel core), R (copper flexible wire). (3) The insulation of cable V (polyvinyl chloride), YJ (cross-linked polyethylene), Y (polyethylene), X (natural styrene-butadiene rubber compound insulation), G (silicon rubber compound insulation), and YY (ethylene-vinyl acetate rubber compound insulation) are the different types of rubber compounds that are used for insulation.
electrical wire types and uses
Not everyone is aware of the different types of electrical wire in terms of what uses they might be put to. To begin, lets talk about the category of wire. A conductor of electrical current is referred to simply as a wire. Wire is typically separated into three categories: bare wire, magnet wire, and insulated wire.
A bare wire is one that does not have an insulation layer and can be made of copper, aluminum, overhead stranded wire, or a variety of other profiles. 1. Power system Overhead bare wires, bus bars, power cables, rubber sheathed cables, overhead insulated cables, and branch cables are the primary types of wire and cable products that are utilized in the power system. Other types of wire and cable products include overhead insulated cables. 2. the transfer of information The local telephone cables, TV cables, electronic cables, radio frequency cables, optical fiber cables, data cables, electromagnetic wires, and power communication or other composite cables make up the majority of the wires and cables that are utilized in the information transmission system.
- Instrument system
Aside from the naked wires that are strung overhead, nearly every other product is put to use in this section, the most common of which are power cables, magnet wires, data cables, instrumentation cables, and so on. Busbars, switch boxes, and outdoor and interior overhead wiring are the most common applications for this material. When employing it, you need to pay careful attention to the usage of the wire, not only to the accurate connection of the joint, but also to the addition of the terminal above the post. By using washers and simultaneously tightening the nut, it is possible to successfully prevent the phenomenon of heat generation at the connector of the power cable. 
wire types and sizes
The following are some helpful hints that can be used to calculate the appropriate wire types and sizes bases on wire gauge, ampacity, and maximum wattage that should be used. If you know how many amps and watts each wire can handle, choosing the appropriate size wire is a piece of cake. Installing a wire of the appropriate size in relation to the circuit's power requirements is the challenge here. Even while some wires may look identical or even be the same size, this does not mean that they are capable of withstanding the current. Copper wire, for instance, is easier to work with than aluminum wire, and as such, it is the material that you should always choose to use for the wiring in your home. Aluminum wire has been present for a good number of years, and despite the fact that it is more affordable, its use has all but disappeared. This is because the aluminum wire is softer, and when it heats up, it gets loose within the wire junction. Copper wire is the most common and recommended material for use in electrical wiring. 
Wire gauge measures the physical size of the wire. Popular gauges include 14, 12, 10, 8, 6, and 2. The wire's gauge indicates the maximum safe current flow. Amps measure current. 14 wires can carry 15 amps, 12 wires 20 amps, and 10 wires 30 amps. Wire amperage increases with fewer twists and larger diameter. Follow this tip to choose the right wire size. 3 types of wire A rundown of the 3 primary types of wire used in the classification of electronic devices! There are many different kinds of electronic wires, which are products of the electronic industry that are ubiquitous in contemporary life due to their widespread use. The requirements of various applications can guide the selection of electronic wire products that are suitable for use. Do you have any idea how the majority of the time, electrical cables are classified, and according to what method? The following provides an explanation of the three primary classification forms that are used by cable manufacturers and cable engineers when referring to electronic wires. 
- The electronic wire can be categorized based on the substance that it is made of as follows: PVC electronic wire, PE electronic wire, TPU electronic wire, silicone rubber electronic wire, and Teflon electronic wire.
- Classification based on the purpose of the electronic wire: it is possible to split it into high temperature and high voltage electronic wire, high voltage resistant electronic wire, and high temperature electronic wire that is resistant to both high voltage and high temperature.
- The electronic wire can be classified according to the number of layers that make up its outer skin layer as follows: single-layer electronic wire, double-layer electronic wire, and three-layer electronic wire respectively.
