10 Different Types of Electrical Wire and how to Choose One

Conduit is typically used where the wiring will be exposed and not hidden inside walls, floors, or ceilings. Conduit is often used in unfinished areas, such as basements and garages, and for short exposed runs inside the home, such as wiring connections for garbage disposers and hot water heaters. The installed wiring should be heat resistant. Long life and Heat Resistance : As the cables are installed every sector show they should require very less maintenance as it is not feasible to maintain them in public or private facilities. Overall the electrical cables are important for efficiently transportation of electrical power in every sectors. These are perfectly used for transportation and distribution of energy. Coax are used for transmitting very high frequency signals with very less loss of energy like for appliances like radio, antennas, transmitters. In electronic and electrical systems, electrical cables are used for transmitting electric power whereas telecommunication cables like coaxial, twisted pair, fiber optic are used for transmitting telecommunication signals from one location to another. The cables are generally color coded. These cables are made of highly conducting material such as copper and aluminum which are easily available in nature.

However, most cables also include a bare copper wire to function as a ground wire- so in effect, there is an extra conductor in each cable.A 14-3 (or 14/3) cable contains a total of four (4) 14 gauge wires, which would generally be used as two (2) hot wires, one neutral, and a ground wire. An electrical cable is an assembly of one or more wires running side by side or bundled, which is used as an electrical conductor to carry electric current. Electrical cables are used to connect two or more devices, enabling the transfer of electrical signals or power from one device to the other. In many cases, these cables are actually buried underground to carry electricity to outbuildings like sheds or detached garages. For example, small wiring that can handle low-voltage applications like landscape lighting isn't qualified to carry the load required for a water heater. Which is the most type of wiring used in domestic applications? The most common type of electric power cable is that which is suspended overhead between poles or steel towers. Protective coverings for electric communication cables are similar to those for electric power cables.

Cables can be securely fastened and organized, such as by using trunking, cable trays, cable ties or cable lacing. The PVC is the most commonly used thermoplastic insulation has maximum temperature tolerance of 70. The higher the temperature tolerance the more the conductor can can carry the current. The most generally use metals are copper and aluminum which are good conductor of electricity. Copper or aluminum is chosen for high electrical conductivity, while stranding gives the cable flexibility. Bunching small wires before concentric stranding adds the most flexibility. However, until you know exactly what kind of wires you are dealing with, it's best to treat them all as dangerous. Steel wire or strands are added for tensile strength, and the entire cable is then wrapped in a polyethylene sheath, or jacket, for stability. Polyethylene, PVC, Kapton, and Teflon are common insulators.Side Note: Wire is used in many applications other than electrical service. Different synthetic polymers are used for insulation. The insulation are made of polymer, plastic layer that cover the conductor it from external contacts.

U0 is r.m.s value between any conductor and insulator. In this design the foil or mesh shield has a circular cross section and the inner conductor is exactly at its center. It consists of 1 or 2 insulated wires which are covered by a woven braided shield or aluminium Mylar foil for better signal transmission and removing irregularities in the frequency of power and external interference in radio. These are applied to isolate the signals that pass through the inner side of the cable and prevent it from external interference. These types of wires are usually used in telephone cables and the resistance to external interference can be measured by the number of wires. The most commonly used telephone and data wires are Cat 5 (category 5) cable and its more modern counterpart Cat 6, which can be used for both phone and data transmission and offer greater capacity and quality than standard phone wire. When the cables are connected to the corrected terminal of the the application allows them to carry the power or current into them. Why we use shielded cables ? This was invented in 1930, but not available outside military use until after World War 2 during which a telegraph cable using it was laid across the English Channel to support troops following D-Day.
