Medium voltage cables
Medium voltage cables are used for single- or three-phase power distribution in systems with a rated voltage of 6 to
30 kV and at distribution line substations. These cables are also used in public and industrial networks, indoor and
outdoor installations, either on land (fixed installation) or inside the canal.
- Its armed type can withstand external physical and mechanical stresses.
- Lead type is stable in environments containing hydrocarbons, solvents and corrosive materials and radially (field) water penetration.

The specialized voltages for these types of cables are as follows:
- U0/U(Um)=3. 6/6(7. 2) – 6/10(12) – 8.7/15(17. 5) – 12/20(24) – 18/30(36)KV
In the voltage distribution of the cables the symbol U0 / U (Um) with parameters U0, U and (Um) represents:
- U0: Nominal voltage between conductor and earth or metal shield in industrial frequency
- U: The nominal voltage is between conductors
- Um: The highest voltage (highest voltage in the network)
Cable Building Details:
- Conductor cross section: Single thread from 35 to 1000 mm cross section
