Catalogue is published with a certain purpose to introduce the different products of a company in simple words. A high, medium, and low voltage wire and cable company in India, as an example, would introduce itself through its product and the simple introduction and uses of each. A wire is defined as an electrical conductor, while a cable is defined as a set of individually insulated wires (conductors) encased in a sheath. A sheath is a non-conductive material with protective properties used to shield the conductive parts of a wire/cable. Although a wire is a good conductor, it can still have some resistance . Wires and cables can be made of different materials such as copper, gold, and aluminum. 
Each material has a different resistance. Thick wires have lower resistance than thin wires made of the same material. The resistance of a wire changes proportionally with temperature or wire length. Wire size is indicated by the diameter of conductor. When choosing the size of the wire, consider the thickness of the wire, the capacity of the wire, and the purpose of the wire. If the wire is too small, it will send too much current, causing the wire to lose more power in terms of watts because the resistance is so high. Solid wire is divided into two types: solid wire and stranded wire (also known as braided wire). Solid wire is stiff and conducts better. Stranded wire is less likely to break when repeatedly bent, which is why this type of wire is common in phone chargers. Jumper wires are pre-cut flexible wires of varying lengths with stiff ends that make it easy to insert the wires into breadboards. Patch cords are typically single-conductor insulated wires for low-current, low-voltage (<600 volts) applications and are used to make internal connections. It comes in a variety of sizes and lengths. 
Once the connecting wire is cut to the desired length, a wire stripper can be used to strip the insulation and thereby connect the metal conductor to the circuit. Magnet wire is copper or aluminum wire coated with a very thin layer of insulation. Magnetic wire makes it possible to twist several layers of wire together without shorting. When a wire is wound into a coil and energized, it generates an electromagnetic field. Magnet wire is commonly used in transformers, inductors, motors, electromagnets, Tesla coils, and other applications that require tight coil insulation. Winding wires are ideal for winding wires, hence the name. Silver-plated copper wire is very flexible and has good insulation, but is resistant to wear. Wire wrapping is great for prototyping because it's easy to make point-to-point connections and repair them. Connections made with wire wrap are more reliable than soldered connections because of the high contact between the wire and the terminal. Muscle wire is an extremely thin wire made of nitinol known for its ability to contract when an electrical current is applied. It has been used in the Micro Latch on the Microsoft® Surface Book Laptop. Check out this more in-depth article to learn what muscle lines are and how they work. As previously mentioned, a cable is a set of insulated wires wrapped in a jacket. Typically, a cable has at least one hot wire to carry current, a neutral wire, and a ground wire. Cables are classified according to the number of wires they contain and their size/gauge. Cables are marked with a series of letters followed by a number, a hyphen and another number. Letters indicate insulation type. The first number represents the resistance of the wires in the cable. The number after the dash indicates the number of individual conductors in the cable. If G follows the last digit, the cable is also equipped with a non-current-carrying ground wire. 
High voltage wire catalogue in India
Catalogue can generally help the customer to make the right decision. For example, if the catalogue was regarding high voltage cable and wire for the market in India, the catalogue would have been designed according to its target market with its standards. When choosing a wire or cable, it really comes down to three overall characteristics: physical performance, functional performance, and supportability. Physical properties determine how resistant the overall structure is to environmental stresses such as abrasion, thermal fluctuations, installation, and exposure to liquids and pollutants. Functional parameters take into account signal attenuation and the ability of the wire/cable to handle power surges without creating a smoke or fire hazard. Finally, supportability considers how human factors and the long-term maintenance needs of equipment play out throughout the maintenance cycle. When selecting a wire/cable, the most important physical parameter is its performance at operating temperature when exposed to temperature, fluid exposure, installation and wear. When it comes to temperature, insulation and conductor limitations should be considered. 
In the case of shielded cables, shielding should also be considered as a limiting factor. Overheating of conductors can cause rapid breakdown of the plating, resulting in reduced conductivity, greater signal attenuation, and increased susceptibility to corrosion. For liquid exposure, although many aircraft wire/cable insulation types are inert to common chemicals, they should be evaluated for the application. If uncommon chemicals are used in any part of the manufacturing or maintenance of the platform, the material must be evaluated for compatibility. There have been several recent examples of fleets implementing new cleaning or de-icing fluids, only to result in severe degradation of electrical components. Tests such as AS4373 METHOD 601 form the basis for evaluating wire/cable degradation due to liquid exposure. Abrasion resistance should be assessed at operating temperature. Wire insulation behaves differently at ambient temperatures than at high temperatures. Some types of insulation can degrade by as much as 50% with just a 10°C rise. These performance changes need not be at 140°C or higher, but in some cases from 50°C to 60°C. If the environment in the installation area is subject to high vibrations or regular maintenance traffic is required, components with high wear resistance are recommended. 
Functional reliability of wires/cables is necessary to ensure that everything else on the aircraft functions correctly. But which parameters should be selected or evaluated when choosing wires? The three factors recommended are current carrying capacity, signal attenuation, and voltage rating. For current-carrying capacity, there is already a wealth of information on recommended maximum current ratings for various wires. This maximum current rating is then typically reduced when added to the harness. Signal integrity is a key property of RF microwave and high-speed data cables. Signals degrade as they travel across the line. The signal attenuation of a cable is frequency dependent and not uniform across the spectrum; typically, signal attenuation increases with frequency. Acceptable attenuation levels depend on the application/equipment/installation and no single cable is suitable for all applications. It is important to note that signal integrity is highly dependent on cable geometry and conductivity, so it is critical to consider bend radii, routing, and other environmental stressors. Most signal attenuation problems can be solved by choosing the right cables that have been thoroughly tested according to the application requirements. Finally, the voltage rating of the wire or cable should be considered. While the nominal voltage of a circuit may be 115 V, in many cases transients from the load or power supply will produce current spikes more than 2 or 3 times higher than the nominal voltage. For pulse width modulated systems these transients are common and frequent. The result is increased strain on the wire/cable's dielectric. Considered individually, voltage spikes and increased power system frequency are not a problem, but the combination of the two can cause a rapid dielectric breakdown. It is recommended to choose cables that can recognize these voltage peaks and have correspondingly durable insulation properties. Each supportability factor is a fundamental logistical consideration for any component, and the same consideration should be made for any wire, cable, or connector located on an aircraft. Choosing a component that is no longer useful after 10 years or cannot be maintained because the tool disappears only creates problems. Often the best way to resolve support issues is to use methods that conform to modern industry standards. Because others are probably using the same components and facing similar support issues. This will result in these components likely to remain available for many years to come. 
High voltage cable catalogue in India
As it was mentioned, the catalogue has a target market. If the target market of catalogue is the wholesalers and buyers of high voltage wire and cable, as an example in India, then the information about the product can be more technical with the technical terms and numbers. For example, as you may know, AC power cords safely carry current and voltage from a household power source to electronic equipment, usually an AC to DC power source. Individually insulated conductors are housed in a more durable protective outer sheath with connectors at one or both ends. Conductor size and quantity, current and voltage ratings, temperature ratings, and agency approvals which are usually printed on the sheath, can be mentioned in the catalogue. Multi-conductor cables are a variant of multi-wire cable, where each cable carries 2-60 different conductors within a common sheath. 
There may be twisted conductors and solid conductors wound together inside the jacket. These cables can be used to connect heavy equipment, medical electronics, audio systems and more. Ribbon cable consists of a series of single conductor wires which are connected side by side to form a ribbon or tape shape. It can also be called zip-wire because the conductor can be separated from the tape. The wires are not wrapped in a protective sheath like other types of cables, but are individually insulated. Coaxial cable has an insulated center conductor surrounded by a braided wire shield which is encased in a hard outer sheath/jacket. Coaxial refers to two or more three-dimensional linear shapes that share a common axis. This type of transmission line transmits high frequency electrical signals with low loss. Some applications include the transmission of TV signals, Internet network cables, and antennas that connect radio transmitters and receivers to them. The coaxial cable consists of an outer plastic sheath, a braided copper shield, an inner dielectric insulator, and a copper core. Speaker cables are two or more electrical conductors (usually copper) individually insulated by plastic or rubber. Both wires are electrically identical but are labeled to identify the correct audio signal polarity. Speaker cables are used for the electrical connection between the speakers and the amplifier source. 
There are three important electrical properties: resistance, capacitance, and inductance. Low resistance allows more source current to pass through the speaker coil, which means more sound.
