Primary Features of Underground Armored Cable

by www.fiber-mart.com
What is the structure of the underground power cable?
 
Plenty of cables and wires are available for all types of electrical and cable applications. Choosing the correct one can be easy enough if you know, as a professional electrician, what application the product is for. Much of the tine armoured cables are used in mains supplies and underground sewer systems or railways.
 
There are a variety of armoured cables available including those that are made of 2 to 7 core wires. Underground armoured cable has distinct features. They are noted for the different number of conductors within them which are covered with insulation and a layer of protective PVC or other durable material. They also have bedding and a sheath. They are comprised often of Huadong steel wire armoured cable and often called SWA wires.
 
What are the advantages of underground armoured cable?
Electrical power can go through the cables underground, although there are some types that work above ground. Underground cables have the ability to endure no matter how bad the weather gets. Click here to know more about custom power cables if you need.
 
They are easy and inexpensive to maintain because they are protected underground. They also tend to fault less often than the above ground cables because there is less of a chance of voltage drops. If overhead lines cannot be installed these are the only option. They are costly to install, but they offer so many advantageous features that it ends up being a worthwhile investment. If you want to buy underground armoured cable, Huadong Cable Group is a good underground power cable factory in China.
 
They are worth the extra price because they also make it difficult for anyone to be injured when coming in contact with them. They are buried underground so this is unlikely unless there is some type of natural disaster that disrupts them when they are buried.
 
What are the performance features of underground armored cable?
Urban lines work better when they can transmit through underground cables. They can go up to 20 circuits whereas the above ground cables only go from 2 to 4 circuits.
 
These cables last a long time because they do not come into contact with water, acids or alkali like above ground wires and cables often do. This makes them a lot more reliable when used in large cities that depend on constant power.buy discount underground armoured power cable quotation
 
What these cables do for cities is keep them looking beautiful. There is less clutter when cables are buried underground. Also, land is an important resource. It can be used in several ways when cables are laid beneath the ground and beneath the buildings to which they supply power. Click here to know more about underground armored cable.
 
There was a time where buildings were strewn with cables for mains supplies. Sometimes, these are still the only option for connecting power sources to buildings. However, instead of having to choose to destroy the look of a row of buildings, underground armoured cables offer the convenience of keeping the look of a neighborhood or city neater. http://huadongswacable.com/underground-power-cable/
 
They also work well to maintain safety for people riding in underground railways. There are many advantages and features of armoured cable. They come in a variety of sizes and offer a lot of durability. They even help keep a city or other urban area looking more attractive, clean and appealing to those who live and work there.

What Cables Should be Used in Wet Locations?

by www.fiber-mart.com
What are wet, dry and damp location?
The definition of a dry location according to the National Electric Code (NEC) is: A location not normally subject to dampness or wetness. A location classified as dry may be temporarily subject to dampness or wetness, as in the case of a building under construction.
 
Based on this definition, standard Armored Cable (AC) or Metal-Clad Cable (MC) may be used in locations that may be temporarily exposed to the elements such as rain during construction.
 
Dry locations are not to be confused with damp locations which are protected from the elements and water saturation but may be subjected to moderate amounts of moisture. Some damp locations may include open porches, barns, under canopies, etc.
 
Wet locations occur in areas where direct burial in the ground, in concrete, etc may occur. These are areas where water or other liquid saturation is possible, or in areas that are regularly exposed to the elements.
 
Options for wet and damp location cable
Many questions center on what cabling products are approved for wet and damp locations. Type AC cable is approved by the NEC for use only in dry locations. In order to comply with the NEC for use in wet locations, interlocked Type MC Cable must have a corrosion resistant jacket and wet location rated conductors. A common style cable that is rated for wet locations is a standard MC Cable with a PVC jacket. AFC Cable Systems® offers Parking Deck/Lot Cable which is UL® Listed and rated for wet locations per NEC 330. Common applications for this cable include parking garages, direct burial, trenched and back-filled, swimming pools for pool motors and perimeter lighting and terminated in a pole base for parking lots and many more. PVC jacketed cable is also an ideal choice for locations where wiring is subjected to occasional dampness.

An added benefit to PVC jacketed cables is the ability to develop a custom jacket color to blend in with the installation environment. Standard jacket color is gray to coincide with parking garages to minimize visibility of wiring.
