Power Cables are far more interesting than you ever imagined! Most of us have just seen these cables as a basic requirement that we don't even care about since their beginnings in 1882. But there are a lot more things to add to these strings of wonder than meets the eye! Thomas Edison produced the first 'wire' in 1882 which wasn't even a wire; instead, it was a collection of copper tubes wrapped in jute! The wire was filled with asphalt, which provided insulation, due to its porous properties because rubber insulation was not employed until 1897, and only in the power plants like Niagara Falls. Here are some things to know more about power cables:

1. Copper does not always perform better than aluminum as a conductor: There are a lot of people to believe that copper cables are always a superior electrical conductor to aluminum. This is incorrect. When it comes to deciding which sort of conductivity is best between these two metals, there are numerous things to consider. The most important of them is that conductivity in cable wires is a unique mix of the size of the cables and the insulation material employed, rather than just a function of the measure of resistance. As a result, aluminum cables are more cost-effective than copper cables when super-high voltages must be transported over long distances.
2. The current capacity of the cable is affected by a variety of circumstances and does not remain constant: It's typical to hear folks speculate that their existing cable capacity will remain stable indefinitely. Electrical cables, however, are widely misunderstood by the general public. The truth is that cable current capacity varies constantly and does not remain constant throughout a cable's lifetime. The prevailing ground or air temperature, the actual way in which the laying was carried out, and the depth at which the cables were laid are frequently the causes of these fluctuations.
