10 Different Types of Electrical Wire and how to Choose One > 자유게시판

This type of cable can easily flex, and it is designed to handle low-level voltages. Ribbon cable is a type of wiring where each wire conductor is attached at its side, creating a flat ribbon-like wire. Likewise, any conductor or cable will pick up energy from any existing electromagnetic field around it. This causes the voltages induced by a magnetic field between the shield and the core conductor to consist of two nearly equal magnitudes which cancel each other. At high frequencies, current tends to run along the surface of the conductor. A grounded shield on cables operating at 2.5 kV or more gathers leakage current and capacitive current, protecting people from electric shock and equalizing stress on the cable insulation. The minuscule amount of voltage carried by coaxial cable signals makes it very unlikely to cause a shock of any type-provided the cables are not in contact with another source of current. These are less dangerous, and with some, the voltage carried is so low that there is virtually no chance of shock. However, there is always a danger of data wiring coming into contact with household wiring, so you should treat it with caution and avoid touching bare wires.

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 first solution to these problems is to keep cable lengths in buildings short since pick up and transmission are essentially proportional to the length of the cable. Power cables are used for bulk transmission of alternating and direct current power, especially using high-voltage cable. Electric devices using power cables that connect to wall outlets using only two prongs instead of three are designed with a floating ground. Three of the principal design techniques are shielding, coaxial geometry, and twisted-pair geometry. Coaxial design helps to further reduce low-frequency magnetic transmission and pickup. Beyond this, there are particular cable designs that minimize electromagnetic pickup and transmission. Different power cables are used for different purposes, and there are several factors behind this. What differentiates power cables from others is that these cables are basically used to transmit high voltages in the systems where the overhead lines could not be used. Power cables as actually the main component of an electrical setup.

What are electric cables or power cables? As, wires and cables are critical part of any electric system, therefore, it is important to use only high quality cables for anything. The first thermoplastic used was gutta-percha (a natural latex) which was found useful for underwater cables in the 19th century. But, when it comes to selecting the perfect category of power cables for your specific needs, you would have to first understand which cable is used for what. Thus, if a power cables’ company has to grow, they have to first make sure that they develop a bond of trust with the market. Also, the company should ensure that they manufacture innovative products which are appropriate for the changing needs of the market. They should manufacture and export only high quality, premium cables. Therefore, there is no doubt about the fact that the wires and cables industry is almost always growing. This ensures that there is no electrical connection between the high-voltage power grid and the low-voltage electronic device, making it unlikely that the device will unexpectedly short-circuit when charging. And, most of the power cables can be bought easily from the sellers.

The second solution is to route cables away from trouble. However, unlike armored cables, metal-clad cables feature a full-size designated ground wire, while armored cables rely on a combination of the metal jacket and a thin wire or strip for grounding. Armored cable, which you may come across in an older home renovation, is a type of wiring that features a metal jacket around the wires to protect them from damage. Armored cable is often chosen for installation in interior locations that are exposed, which would leave the wiring vulnerable to damage. Low-voltage wiring is used for circuits typically that require minimal voltage, such as landscape lighting wires, sprinkler system connections, bell wires (for doorbells), speaker system wires, thermostat wires, or anything else that requires 50 volts or less. All wires running inside this shielding layer will be to a large extent decoupled from external electrical fields, particularly if the shield is connected to a point of constant voltage, such as earth or ground. It consists of two or more individual wires wrapped inside a protective plastic sheathing. The first, and still very common, man-made plastic used for cable insulation was polyethylene. NM cable usually contains one or more "hot" (current-carrying) wires, a neutral wire, and a ground wire.
