Things You Must Know Before Purchasing Power Cables

Power cables are the prerequisite things to start any electrical system. From very thin to high power suppliers, there are so many types of cables are available in the market. For different purposes, different types of cables are used. Let’s get closer to the genuine facts and functionalities of power cables available in the online or offline market.

Cable Current does not remain the same and stable all the time

It is a big misconception between people that the cables they are using remain always the same with their current flowing capacity. The cable current capacity changes time to time and never remain the same during its lifetime.

Copper is not always a better conductor than aluminium

Most of us believe that copper is always a better conductor than the aluminium. You must know that the fact owned by your mind is inaccurate. It all depends on the insulation material and length of the cable used. You must have noticed that aluminium wire has been used in long-distances and for super-high voltage transfers as these cables act as highly economical and best control cables.

Cable armour is not used to protect the cable

The armour you see around the cable is not provided to protect it against physical damages. It increases the tensile measure of the wire. Opposite to it, if the wire exposes due to some physical intact, it may cause severe damage with the help of armour.

Cable armour is not meant to prevent moisture

You must know the fact that the cable armour is not provided to prevent moisture. It only helps wire not to bend much as it can be broken inside. The armour is not meant to protect the wire from water or any kind of moisture. Even the best control cables do not provide much capable armour that can prevent moisture.

'New' doesn’t stand for long-lasting

It is a misconception between people that new power cables will stay for a lifetime. There are so many power cable manufacturers in the market. So the power cables you are using in your house may stay for a limited period of time.

Hope, this information helped you a little to know the facts and capacity of power cables.

1. The first ever ‘wire’ was developed by Thomas Edison in 1882. It wasn’t even a proper wire, it was basically made of copper tubes wrapped in jute! It’s was filled with asphalt, which provided insulation, because of it’s bituminous properties. This is because Rubber insulation was not used until 1897, and that too in the Niagara Falls power project.
2. Copper may not be a better conductor than Aluminum, after all! Yes, you read it right! In some scenarios like transmitting high voltages over long distances, the material and size of the wire is such that aluminum proves more efficient and economical as compared to copper!
3. Cable armor is basically useless! We often expect cable armor to protect the cables from external wear and tear, and also form the harsh weather conditions. But in reality, the armor may sometimes end up causing more damage! Most of the armors are made up of steel tapes or steel gauges, which, when bent can cause the wire to malfunction. Also, in contrary to a well known myth, most people believe that armor can protect the wire from moisture, whereas it is actually the opposite of that! Exposing armored cables to water can cause the wire to cause damage to the armor and eventually destroy the armor.
4. New cables may not work like ‘new’ for long! New wires have different specifications, from different manufacturers and are designed to work in quite different scenarios. For example, manufacturers like Prime Cable Industries Pvt. Ltd. produce wires of exceptional quality, but if you install a low tension wire in a place where high tension is required, the damage can’t be blamed on the brand. It is the fault of the installation that causes such wires to lose life almost immediately after their installation.
