FAQ

Question 1: What is a cable?

Answer: A cable is an electrical conductor sheathed with insulating materials. During cable production, several insulated conductors are usually stranded together and provided with additional protective layers (e.g. inner jacket, electrical shielding, outer jacket).

Question 2. What is a cable made of?

A: The design of a cable can be simplified as follows:
A conductor is a cable that is covered with insulation and carries an electrical current.
Conductor:   Primarily copper, more rarely aluminum or nickel.    
Conductor insulation:    Various plastics are used as insulation material including PVC, PUR, PE, TPE, PTFE, FPE, and rubber.
Possible protective layers
Inner jacket: Various plastics are used as the jacketing, see outer jacket.  
Electrical shielding: Braided shield and foil shields.  
Outer jacket: Various plastics are used as jacketing, see typical outer jacketing.

Question 3. What is the difference between an electrical and a power cable?

Answer: The layman in the private sector will usually refer to power cables and LAN cables. Electrical companies, on the other hand, want to lay electrical cables from the domestic junction box to the counter cabinet while telecommunications companies, in turn, work with telephone power cables and fiber glass fiber cables. However, when it comes to extending the power grid, people hear about overhead power cables and cables for direct burial.
