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!

Anyone who has ever tried to plug in an appliance only to find that it wouldn’t turn on is familiar with how frustrating electrical outlet wiring problems can be. The whole purpose of having outlets is the convenience, but that goes right out the window when they stop working without warning. Although a dead outlet might automatically seem like a big problem, sometimes it can be due to a simple issue. This isn’t always the case, of course — sometimes there will be electrical outlet wiring problems that can only be addressed by a professional, particularly when the issue is with your outlet’s wiring.

You might be able to save yourself a call to an electrician if your outlet problem is something easily fixed. You can even resolve some minor issues without the use of tools! If you know what steps to take, you may be able to figure out if the dead outlet is something you can remedy yourself. If you discover the problem is something that should be handled by a professional, don’t take any chances. Messing around with wiring can put you in danger and damage your electrical system instead of making the problem go away.

A simple issue can quickly turn into a very expensive one if you aren’t careful. Here are some easy things to try that won’t put you in any danger:
