Features choice of medium voltage cables

Abstract
Power medium voltage cables with plastic or rubber insulation is almost universally used for the transmission and distribution of electricity, as in municipal networks as well as in industry. The total number of single-core cables used exceeds the number of three-core

Results
The main advantage of a three-core cable is the fact that in the three-wire cable at any one time the sum of the current in the three veins zero. Net magnetic flux in the space surrounding the core at some distance from them almost as equal to zero. For this reason, there is no loss of spurious interference.
Conclusions
The advantages of using a three-core cable instead of solid clear and justified from both a technical and an economic point of view
