How to distinguish between high voltage cable and voltage cable

There are many cables used in our daily work and life, which can be basically divided into two categories: low-voltage and high-voltage. So how to distinguish high-voltage cables?
First of all, in terms of appearance, the insulator of the high-voltage cable is very thick, generally about 1 cm, while the low-voltage cable looks thinner. The common low-voltage cable is similar to the data cable we use every day, or it is thicker.
There is also a more important feature, which is to look at the cross-section of the cable, because the high-voltage cable has a shielding layer, which is a structure that the general low-voltage cable does not have. The high-voltage cable needs to carry a strong current, which will generate a strong electric field. Therefore, the high-voltage cable needs to be provided with a shielding layer to shield the interference to the outside world.
