What Is The Difference Between A Cable And A Wire?

Experts in the electrical industry speak of a cable when it is laid as an underground cable in the ground and on the seabed. The most important feature is that a cable remains invisible, whereas an overhead or high-voltage line is visible to everyone. A cable combines any number of conductors and, depending on the type, is equipped with cable protection or shield. The core lines are encased in an insulating PVC sheath, designed for different mechanical stress levels.

Accordingly, one speaks of a line if it can be seen. Strictly speaking, this also applies to a concealed installation cable because it leaves the wall and appears at the junction box, at a switch, or the consumer. Cables for cable protector outdoor often consist of several individual cores, which are combined by a sheath. Sometimes, however, it is a matter of so-called overhead lines that occur with non-insulated conductors.

The numerous definitions available, however, differ in a few points. Some explanations refer to all power wires permanently installed in the house as cables and point out that use outdoors is not possible due to the inadequate insulation. The use of cables in distribution systems and control cabinets is also mentioned.

Regardless of any attempt at explanation, the term cable is used rather than the line in practice. The best examples of this are the cable drum, the cable connection, or the simple sentence: I’m going to buy a cable now. In all of the cases mentioned, following the definition given above, it should be called wire instead of cable. But who has ever heard of a cable reel or a cable connection? And if you want to buy a cable, you often come across salespeople who look incomprehensible.

In addition, the rules of electrical engineering AD ABSURDUM are generally used in communication and information technology. There are network cables, WLAN cables, HDMI cables, fire alarm cables, audio cables, and data cables. Strictly speaking, all of the products listed would be cables, but the term cable has established itself over time.
