Power Cords – the most inevitable parts of any electrical equipment. If you search online, you will find several types of extension power cords and other cables that serve a specific purpose. The purpose behind the utility of these cords is dependent on an array of factors including the technical specifications, the location of utility etc.
You might be aware of the electric cords and their workings but you might be unaware of their making and internal workings of it. Through this article, we will acquaint you with 5 unknown facts about power cords. Here we go!
Not All Power Cords Last Long
People often expect the new power cables to last long. However, it isn’t necessary that just because it is new, it will last long. This is because there are several nuances to a power cable including its durability, usage, capacity and other characteristics.
Sometimes, the durability of the cord also depends on the method of installation. If you do not get them installed properly, they are sure to affect the life expectancy of the cords. Also, you need to remember that there are several manufacturers out there who are into manufacturing cables. Which means, that not all of them are meant to last long. It is always advisable to check the lifeline of these cords before you buy them.
Not All Cable Jackets Offer Moisture Protection
People mostly believe that the jacket or the outer layer of cords protect them from the moisture. This isn’t always true. Some extension power cords, if exposed to water may damage the armor of the cable leading it to getting exposed to water and damaging it in a long run.
In case you are planning to implement the installation of any of these cords, it is advisable to get in touch with professionals or the building inspector. By doing so, you will be able to ensure that they meet all the required regulations and won’t have troubles at a later stage.
Not All Protect Against Physical Impacts
Again, cable armors do not always protect against physical impacts. In fact, if you expose it to too much physical stress, you might damage its functionality. The armor of power cords consists of steel wire or tape. And these materials enhance the effect of a physical impact.
Copper – Not Always Better
Electricians often claim that copper is a better electricity conductor as compared to aluminum. But this is incomplete information. Talking about the two types of conductors, there are several factors that one needs to consider. One of the most important factors amongst this is the conductivity in relation to the cable wires.
The conductivity is not all about resistivity but an amalgamation of insulation materials and the size of cables. So, whenever one needs to use high voltage along long distances, it becomes more cost-effective to used aluminum cables.
Current Capacity is Relative
The current capacity of extension power cords doesn’t remain consistent forever. There are several factors that affect the current ratings. These fluctuations happen due to factors like air and ground temperature, the way in which earthing of the wires have taken place, as well as the depth up to which the professionals have laid the cables.
It is better to have clarity with these points then to know about it later and face the consequences. These days, you can buy power and extension cords online. However, you must make sure that the company you are buying from provides standardized cables that come with a lifetime warranty.
Also make sure that the cables/cords that you order are ROHS compliant. Once you fulfill what your checklist entails, things hardly go wrong with cable currents. Buy from SF Cable, Buy from the best!
