this is a 5 strand cable with conductor (Aluminium) crossection area 70mm2

The conductors are uninsulated- for overhead power distribution/transmission

PS: safe Current carrying capacity approx 150A

Depending on what its being used for. You could have three strands for the overhead high voltage. One for the neutral (little lower) and one to feed the street lights. Equals 5.

You could have 5 secondaries. One neutral- 3 for 3 phase and one control wire for the street lights. All open wire.
