Many aerial cables, especially those operating at high voltages, are bare (uninsulated). As compared to optical fiber or coaxial cables, UTP cables are more reasonable. Fiber optic cables are unsafe. UTP cable is less costly as compared to optic fiber & coaxial cable. Coaxial cables have higher bandwidth & less expensive as compared to FOC or fiber optic cables. Over time however it is the more economical choice as you will have to deal with less maintenance costs. The whole construction of these cables will change based on some factors like the voltage, temperature, electrical performance, etc. These cables can be made with different shieldings like foil, spiral, or braid. The characteristics of the current that will flow through these cables will affect the choice of AC or DC cable for the projects. These cables use gas or oil to maintain the pressure of the cable above the atmosphere. These cables are available in two types gas pressure and oil-filled.

Super Tension, Oil Filled & Gas Pressure. The electric cable disadvantages include the following. How to Determine Cable Size? How do I determine electrical cable size? This PS/2 (Personal System/2) cable is available with a round connector with 6 pins. Please refer to this link to know more about VGA Connector. VGA (Video Graphics Adapter) cable is mainly used to transfer video signals by connecting the CPU & monitor of a computer. These cables transmit video data to monitors at high resolutions like 2560 x 1600, so these are mostly applicable in CRT monitors with a VGA connection. These are made from high conducting metals like Copper and Aluminum which have low resistance and can be used for high voltage applications. Thus, the bigger ones can carry more amperages without overstressing the security limits. These cables carry TV signals and connect video equipment. The higher the maximum operating temperature of an insulation, the more current the conductor can carry. MIDI (Musical Instrument Digital Interface) cable carries music data, panning, vibrato, event messages, etc. These cables can be found in different earlier computer systems where sound cards include MIDI ports that joint different electronic musical instruments to computers.

The devices which are connected by USB are music players, mice, keyboards, flash drives, and many more. The USB (Universal Serial Bus) is very popular and standard cable used to connect different peripherals to a computer device. The cable which is used for the transmission & distribution of electric power is known as electrical cable. These cables are frequently used to provide an electric supply for large appliances. Shielded twisted pair (STP) cables have a large diameter and are more expensive as compared to coaxial or UTP cables. Overhead cables are cheaper because they do not have the problems with the inclusion of insulation material and the required properties in their manufacturing process. Thin wall - a harder grade of PVC cable with better electrical insulation properties. Metallic sheathed cable is also called BX, armored cables. It is commonly called a 300 Ω line because the line has an impedance of 300 Ω. Sometimes, a coaxial cable is also called heliax which includes an insulating layer.

These cables are very similar to telephone cables but it includes the number of wires. Cable sheathing includes different insulating material layers & weatherproofing. Underground feeder cables are very similar to NM cables, but instead of every wire being separately enclosed in thermoplastic, wires are connected together & fixed in the flexible material. These cables do not need any extra sheathing, piping, or insulation before being placed underground. UTP cables including solid copper cores & copper wires are popular choices because they are flexible to use on walls. These types of cables contain flexible plastic jackets including 2 to 4 wires and also a bare wire used for grounding. Not all types of cables perform the same function but it depends on different types of cables like Electrical cables, computer cables & Power cables. Power cables like screened cables are applicable up to 33KV of the voltage range, however, in some cases, what is electric cable the voltage range can be increased up to 66KV. These cables are available in two types like H- type and SL type. It is one type of computer cable, used to transmit the signals like audio & video through images. Generally, the Ethernet cable is used in a wired network to connect different devices like PCs, routers & switches in a LAN.
