Power cables are the basic components of any electrical system. There are different types of cables that are available in the market. The choice of which specific cable types should be used for specific purposes is based on several factors, the most important of them being the technical specifications of the functions.

As much as you may be conversant with electric cables, it is possible that there are things about power cables that are new to you. Here is a brief outline of some of the things about power cables:

Many people believe that copper is a far better conductor of electricity than aluminium at all times. This is inaccurate. When it comes to matters of what type of conductor is better between these two metals, there are many factors that need to be taken into account.

The most important one of them is that conductivity in relation to cable wires is not merely a function of the measure of resistivity but rather a unique combination of the size of the cables and the insulation material that is used. Hence, in cases where super-high voltages have to be used over long distances, it becomes economical for one to use aluminium cables as opposed to copper ones.

It is common to hear people talk of the possibility of their current cable capacity to remain stable forever. Incidentally, this is a common misconception about electrical cables that people hold.

However, the truth of the matter is that the cable current capacity changes all the time and does not remain stable over the lifetime of the cables. These changes are usually caused by factors such as the prevailing ground or air temperature, the actual manner in which the laying has been carried out and the depth at which the cables have been laid.

There are several reasons as to why newly installed power cables do last as long as people expect them to. The first one is that since there are many manufacturers of electric cables, it is highly unlikely that all the power cables that you install will last for a specific period of time.

The second one is that there are many different types of power cables. A specific type of power cable is defined in terms of its capacity, durability, usage and other industry-specific characteristics.

The third one is that the extent to which a cable lasts heavily relies on the manner in which the installation is done. A poorly done installation may significantly shorten the life of a cable.

The armor that is used on your cable is not meant to help in protecting the cable against any chances of physical impact. On the contrary, if any type of power cable is exposed to a form of physical stress, it is possible that the damage to the cable arising from the impact is likely to be aggravated by the armor!

A Look Back At 2011

Texas residents suffered damaging and costly electrical problems in 2011. Three major blackout incidents, two of which happened in the winter months of February and December respectively, left residents without heat and without power for hours and, in some cases, days at a time. Equally distressing was the 71-day drought that had Texans begging their local Dallas electrician for relief, as 100-plus degree heat waves weakened the power grid once again and left residents without air conditioning or electricity.

2012: Not Much Better

Unfortunately, 2012 does not seem to be the year for relief. Experts warn that several factors point to an even more severe blackout and power grid problem in the state of Texas for 2012.

 These factors translate into miserable, costly blackouts and power grid failures throughout North Texas.

Though they all have hustle and bustle, lots of buildings, and usually traffic, when you’re on their streets you would never mistake San Francisco for Cairo, Toronto for Tokyo, or Berlin for Rio de Janeiro. But what about from space? During the day, these cities tend to blend in with their surrounding countryside. However, when lit up at night, it’s easy to see how varied these cities can be.

Is it possible to tell anything about the life and culture of our cities when viewing their lights from above? You might be surprised at how much.

Halloween is no doubt one of the most festive times of the year and decorating for the season is a fun and cherished pastime enjoyed by many families. Unfortunately, as almost all Dallas Electrician, ElectricMan Inc. would like for you and your family to enjoy the ghoulish festivities while practicing electrical safety, so here are a few tips for making the most out of decorating for this exciting time of year.

The Hazards of Halloween Decor

When people talk about Halloween decorations, they’re often thinking about lots of lights combined with smoke machines, spiderwebs and paper decorations, all of which can be cheaply made. The down side of these homemade special effects is that many of these decorations are made of highly flammable material which, if left unattended and in close proximity to electrical lighting, can be anything but fun.

Another problem that often arises from Halloween decorating comes from using electrical lighting and components with electrical wiring that has become cracked and damaged over time. Any cracks in the insulation or damage to the wires can prove frightening and sometimes even deadly. Furthermore, heavy usage of lighting and decorations that require electricity can put a strain on extension cords, power strips and electrical outlets in your home, straining your home’s circuits.
