Power cables are lines consisting of one or more conductors that are used to transmit electricity. They consist of at least two elements: conductor and insulation. At the 110 kV voltage level, cables are complex assemblies of several different elements that serve for reliable and safe cable operation. Due to increasing urbanization, where transmission is not possible with overhead conductors, the need for 110 kV cables has never been greater. It is possible to describe the elements of the cable mathematically, in order to be able to calculate the permissible current load of the cable so that it does not overheat. There are various techniques for laying 110 kV cables, but the most popular method is laying them directly in the trench. When laying, there are various technical rules that must be followed in order not to damage cables or other infrastructure. The cable network, of course, consists of all accompanying cable accessories in addition to cables. Cable connectors are used to connect cables on longer routes, while cable terminations are used for termination. Cables are protected with surge arresters.The flow of current through the main conductor of the cable creates a magnetic field, which induces a voltage in the cable screen. Since the cable is not dimensioned for this, the cable screens must be grounded. The main criteria for grounding the screen are the safety of equipment and personnel and minimal heat losses due to the flow of circulating currents. There are various methods of grounding the screen, but the most optimal method at the 110 kV level is the cross-bonding of the cable screens.
